Twitch App Access Tokens can do MORE!

In the beginning App Access Tokens could just load public data, that didn’t need any oAuth scopes, from Twitch API. And so any given developers project had to maintain a user access token(s) for users of their application.

Then extensions were introduced, bundled in Extensions are Subscriber support, allowing extensions and their EBS to read a given viewers subscription status to a channel, outside of the Extension JS Helper function to check the status in client side code. That then leaves how does an Extension EBS (aka Backend Service) perform the same call (since you should never trust the client) to perform the same check.

And so Extension generated App Access Tokens, could call Get Broadcaster Subscriptions. The first endpoint that is scoped that an app access token could load on behalf of a user.

Since then various aspects of Twitch Developer Tools have come and gone, we lost WebSub, and we lost PubSub, and we lost both (over time) in favour of EventSub. There is a bunch of other stuff that happened but the important part here is that with the loss of PubSub, Eventsub achieved “featured parity” with PubSub and a number of other things introduced Chat over Eventsub.

EventSub

An Extensions ability to grant the ability for an app access token to call subscriber information is baked into the “install an extension” work flow.

An extension that offers the Subscription and Chat permissions (chat here has it's own endpoint using JWT), but subscriptions grant the power for app access tokens to be able to read.

But EventSub introduced the dual (or even triple) legged auth approach.

First a user will need to perform a user oAuth loop, either Implicit, Authorization Code, or DCF (Device Code Flow). This then creates a link between the user and the ClientID along with the scopes requested.

Combine that with the recently added Get Authorization By User endpoint to check what scopes your ClientID has to a given user, you can check permissions before trying to create EventSub Subscriptions for Webhooks or Conduits.

So for eventsub the pattern is:

  • Check the conditions and scopes needed for the EventSub Type/Topic
  • For the user’s in the condition get that user to user authenticate with the needed scopes
  • Generate an active app access token (if you don’t have one already)
  • Create the Subscription

As an aside you can use “user.authorization.grant” to easily monitor for new user authentications and create subscriptions as a follow up, if say your user token gen is air gapped from your Eventsub handler. This is a pattern I use on the IGDB Extension to monitor for authentications and create subscriptions to stream.online/offline and channel.update (which yes are public topics but become cost 0 _if_ the user is authenticate to the Client ID, and I use the user.authorization.revoke to unsubscribe since I only want to keep cost 0 subscriptions), becuase the IGDB Extension config page launches an implicit flow since I don’t need the user token ever I just need to auth so creating one with a refresh token is overkill, but I digress….

So that briefly is how EventSub dual legged auth operates.

Chat Over EventSub

Then along came Chat over Eventsub and a bunch of separate topics essentially providing IRC chat as a already JSON-ifed consumable feed.

This also came with Conduits and the ability for chat bots to scale to as many channels as needed, because the broadcaster auth’s the chatbot to be present on their channel. It is similar to how adding Discord Bot to a Discord Server works from a broadcaster point of view.

But chat over eventsub specified two user ID’s in the condition. (which yes can be the same ID but we’ll skip that for simplicity).

So first a developer would

  • Create a Client ID (generally owned by their own Twitch profile but the other of a Client ID is irrelevant, it’s always whom auths to the client that is important)
  • Create a Twitch account with the username of the bot they want to use
  • User Authenticate the bot to the Client ID with the relevant scopes
  • Then authentication any number of broadcasters to the Client ID
  • Now you can rejoin all channels with one API request (update shard), great for restarts or outages, as restart the websocket, call update shard, and then the bot is back in all rooms, no more slow roll rejoins or rate limit joins/etc.

So that is briefly the triple legged auth of chat over eventsub.

So What about App Access Tokens on the API?

Send Chat Message was introduced at the same time as chat over eventsub and is the first “proper” endpoint that worked with App Access Tokens following prior auth from the user(s) involved, (the broadcaster_id and sender_id)

This meant that for “general” operations a chat bot still needed to load and maintain either the broadcasters user token for Start Commercial for example, or the bots own token for Banning a User from chat.

So a bot would be juggling and maintaining up to three tokens,

  • A broadcasters token for broadcaster based operations
  • A bot token for doing moderation actions (for example), or sending chat
  • An app access token for subscription management (or sending chat)

But, now, as of yesterday! For the most part that is no more!

Well Spill the Beans then!

TWENTY ONE API endpoints now support this pattern of using an App Access Token after performing prior user(s) authentication(s). Look for the Beta tag under the Authorization section of each endpoint.

Here is the list:

Anything marked in bold with a * has additional scope requirements compared to the user token version, please check the docs, but I suspect your bot will likely already have obtained the scopes.

So now a chat bot broadly doesn’t need to maintain or even keep on file a user access token for itself or the broadcaster, as most general operations a bot is gonna do will work using the App Access Token. This also comes with the bonus that a user access code flow token is only good for 4 hours but an app access token is good for much longer. (Remember to utilise the Validate Token Endpoint to check time remaining on a token)

I’ll note that “Get Clips Download” supports this pattern, but that API was introduced with the pattern.

But a Sadness

However, the obvious missing endpoint that doesn’t support this pattern is Send Chat Announcement which I hope is supported soon, I think that’s the only one I need to token juggle for at the moment.

Summary

Thats it! Go forth an App Access Token! And hopefully more of the API will support this pattern over time!

If you need further help please join as over on the Twitch Dev Discord or Support Forums!

Bonus Thought

Cronjobs that need to do something on multiple users/broadcasters, the script starts, loads the token, does the job and just switches the user ID no token switchin’!

OBS 32.0.0 the one that will be pain (sorta)

Well OBS 32.0.0 is out, and it’s gonna be pain, but in a good way, wait is pain ever a good thing.

It’s similar pain to the OBS 28 to anything after 28 move but PAIN all the same.

Along with all the new shiny features, like FiniteSingularity’s Plugin Manager, theres a bunch of changes under the hood! And the “Streamer Important” of these changes are what this blog post is gonna blog post about!

You can go read the full change log, over on the Releases Page, new shiny features at the top!

OBS 32's Plugin Manager

Look at this AWESOME Plugin manager. (OBS on line 2? Well thats Logitech’s Plugin apparently… go figure)

So What Broke

So since I have a finger in a LOT of pies, not just on Twitch but other realms, all within Streaming space, I’ll pull OBS Beta’s as they come and start testing. (Curse past me for setting my Mac OBS to always grab the betas… but whatever)

So, I pulled down OBS 32.0.0 beta 1 and it crashed on Launch. Here is the GitHub report yeah in the OP I was blaming EVERYONE and their dog (not Finite’s Dog). Took some better knowing peeps to trace it down and at the time I was busy and couldn’t do my own tracing. (Was too busy OMGWUT-ing to “upstairs” with “please don’t let customers go to 32.0.0 just yet)

Beta 2 fixed the crash on launch issue. But the problem here was the Streamdeck Plugin calling something that was removed from OBS in 32.0.0, since under the hood changes are dropping support for some legacy/older plugin hooks (or so I believe), and the SD plugin was invoking that and the fault wasn’t “safe caught” leading to OBS to crash instead of skip plugin loading.

Elgato was informed and so they chimed in with a “we are on it“, praise be to Videophile.

OBS 32.0.0 is General Release

So OBS 32.0.0 is now “released to the masses”

Heres what you need to do step by step, these steps are valid for OBS 31.x.x but shouldn’t be different for Older OBS, if on OBS Portable HAVE FUN! But you should know what you are doing here if you are running portable anyway…

  1. “File” -> “Show Settings Folder”
  2. Take a copy of the folder “basic” your scenes and profiles are in here and you should routinely back this up. (sure this doesn’t backup media assets (images/videos) that your scenes use thats up to you to sort but will preserve file paths and the like)
  3. Close OBS
  4. Next to update Streamdeck, first check that Streamdeck itself is “recent” should be running at least Software Version 7.0.0. Hit the “Cog” -> “General” -> “Check for Updates”. (At time of writing V7.0.1 is available) this step may also do the next step for you.
  5. If Streamdeck has updated it’ll restart, next Hit the “Cog” -> “Plugins” -> Scroll to OBS Studio, “Check for Update”, anything newer than 2.2.8 and you should be good. (Current version is 2.2.9.9), side note: most plugins have auto update, but some plugins you installed before that was a thing won’t so check those manually if you want.
  6. Now Open OBS and let OBS update to 32.0.0 (do “Help” -> “Check for Updates” if not auto prompted)
  7. Away you go!
Streamdeck showing running version 7.0.0 - Build 22005
OBS Studio plugin for Streamdeck showing "outdated" 2.2.8

Other Plugins

After Restarting OBS into 32.0.0 you’ll want to check for and update any other plugins you use/consider important before you go live for the first time.

Notably ratwithacompiler has put out an update for the Closed Captions Plugin, that a lot of people use (and the one I recommend to people for adding CC’s to your streams), during the OBS 32.0.0 beta phases, to fix a similar fix to what Elgato has needed to do.

But everyone installs different plugins, and currently Plugin Management is manual and not all plugins with hint you need to update. (Why “currently” you say? Well the new Plugin Manager is going to be looking at hinting for updates I understand! YAY)

Aitum Multistream will for example, but I don’t think they have any updates at time of writing. Since it works fine under OBS 32.0.0, I just know it has a visible thang for “update available”.

Post Amble

Just doing my OBS updates, nice alert 😀 I know which ones I need to go and do now, but if you have other plugins make sure to check manually in case they didn’t get reported as not loading!

The End of Twitch PubSub

Finally Twitch EventSub is at feature parity with third party supported/documented PubSub, that the end of PubSub has been announced.

In a forum post over on Twitch Developers it has been announced the schedule for the shutdown of Twitch PubSub for access by third party developers.

The final death date is April 14th 2025.

Which I guess means it’s time for me to complete my own migration from PubSub to EventSub. Which at least is JUST ABOUT planned….

At least for 90% of what I need it’s ALL USERNOTICE as an EventSub topic, which is this case is channel.chat.notification and then whatever I choose to go with for consuming cheering.

So then for anything else I’ll need that doesn’t exist, either from it not existing in the first place OR a undocumented topic I might be using, off to uservoice I’ll go!

Off hand I think there is only one thing but we’ll see when I work on and complete my migration! The only other barrier is gonna be authentication but I have authentication or can get it for everything I need.

It is worth noting that Extension PubSub is unaffected, as that for the most part is a completely different system that just shares the same name.

Topic Migration notes

Edit: I guess I should add some notes about migration

PubSubEventSub
channel-bits-events-v1.<channel_id>channel.cheer or channel.chat.message
channel-bits-events-v2.<channel_id>channel.cheer or channel.chat.message
channel-bits-badge-unlocks.<channel_id>channel.chat.message – the bits_badge_tier
channel-points-channel-v1.<channel_id>channel.channel_points_custom_reward.add
channel.channel_points_automatic_reward_redemption.add
channel-subscribe-events-v1.<channel_id>channel.chat.notification is what I will use for my use case of overlay/on stream alerts. Other type segregated topics exist

This topic also includes raids and a bunch of other event types
automod-queue.<moderator_id>.<channel_id>automod.message.hold and automod.message.update
chat_moderator_actions.<user_id>.<channel_id>channel.moderate
low-trust-users.<channel_id>.<suspicious_user_id>channel.suspicious_user.update and channel.suspicious_user.message
user-moderation-notifications.<current_user_id>.<channel_id>channel.chat.user_message_hold
whispers.<user_id>user.whisper.message

This Post was updated on February 2nd for additional migration paths and adding a link to the new PubSub Migration guide

The First shutdown window is February 10th at 7pm UTC for an hour!

Twitch Extensions: Part 3 – The Architecture of an Extension

In Part 2 we spoke a fair bit about “the path and file name of the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL”, and this week we will cover why I mentioned that every time!

So, this week The Architecture of a Twitch Extension!

An example of Architecture from Wikipedia, The Pyramids at Gizah - © CC BY-SA 2.0
An example of Architecture from Wikipedia, The Pyramids at Gizah – © CC BY-SA 2.0

Basic Architecture

We have covered before that essentially a Twitch Extension is a “Website” that is iFrame’ed onto the Twitch Page, into an integration slot, but what does that actually look like?

The Twitch Architecture Overview
The Twitch Architecture Overview – According to Twitch

This is the “stack” that represents how an Extension is loaded, to illustrate this, we’ll use FlightSimTrack installed to the FlightSimTrack Twitch channel

  • First we have the Twitch Channel page – the “Browser” above
  • Then the Twitch Extension “supervisor”, this basically handles any handshaking between the outer Twitch and the inner Extension, we can’t cover more about it as it’s not documented anywhere, and that is my theory on what it does! It is mentioned in passing in the documentation
  • Then the Extension itself – the “iFrame” above

Relative path? WHY?

So why “relative path”? Well here is what the URL to the Panel looks like for FlightSimTrack

https://q6gmlap07mpxekhpspevz2sq5xjth7.ext-twitch.tv/q6gmlap07mpxekhpspevz2sq5xjth7/ 0.0.2/78753d6eeea69840398d8e46ff018e3b/panel/index.html?anchor=panel&language=en&locale=en-US&mode=viewer&state=released&platform=web

The first thing we’ll notice is that the index.html is in a sub folder of the domain. And NOW you know why we said “the path and file name of the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL” every, single, time. And it’s a common hiccup that Extension Developers run into, a number of people come into the Developer Discord needing extension help, and they either made a mistake packaging the Zip for upload (we’ll cover Upload procedure in a future post), or the developer has used an “absolute” link to a JS/CSS file (starting /style.css or https://example.com/style.css for example, instead of just style.css).

But lets break down this URL, into it’s parts

URL breakdown

https://extClientID.ext-twitch.tv/extClientID/Version/md5OfZip/path_to_file_for_integration_point.html?querystring

We’ll cover the Query string parameters more in a future post, but you can read about them in the Extension Documentation Reference

The most important one to be aware of right now is anchor which tells you which integration slot this is. In this example it’s a panel, and FlightSimTrack’s panel is configured to load panel/index.html for this integration slot.

  • extClientID is obvious, it’s the ClientID of your Extension
  • Extensions live on the domain extClientID.ext-twitch.tv, why a different domain for each extension and separate to Twitch? This prevents any issues with Cookies from the “main” Twitch Website, so there won’t be any session hijacking or other crazy things, you can read a little more on that in the documentation
  • Version – the version of the extension that these files are for
  • md5 of the zip file that was uploaded, during testing you might go to Hosted test/local test (two Stages of the Extension Lifecycle that we’ll cover next week) a few times, so the md5 will change, this is a easy “cache defeat” when you are Hosted testing
  • Final part is the path and html file you specified in the console to load for this integration slot

Asset Hosting for FlightSimTrack
Asset Hosting for FlightSimTrack

The URL structure is the same for every integration point, and all files are considered “public”, which is something to consider when building in things for Channel Moderators to use.

That about covers everything for the frontend

Well, what about the Backend?

Oh you want the backend to do you?

The Twitch Architecture Overview
The Twitch Architecture Overview – According to Twitch again!

First of all it’s important to note than a Backend, also referred to as EBS or Extension Backend Service, is entirely optional, depending on your Extension, what/how it functions or what it does, it might not even need an EBS, either from calling Public API’s or from it being completely self contained.

The SSL Requirement

But for those Extensions that need an EBS, there is essentially one rule, it must serves it’s contents over SSL, this isn’t just good for Security, but is required as the Twitch Website is over SSL and browsers will reject Mixed Content (loading non SSL content from SSL).

So

  • Loading from the EBS? Needs to be https://urltoyourebs/
  • Loading from a Public API? Needs to be https://someapi/
  • Loading from a Websocket? Needs to be wss://somesocket/
  • Loading an image from a CDN? Needs to be https://somecdn/image.png

To illustrate some examples:

  • FlightSimTrack viewer, nothing at all (images are on the Twitch Extensions CDN and map tiles come from map tile vendors over SSL)
  • FlightSimTrack config, EBS lives at https://twitch.extensions.barrycarlyon.co.uk/
  • CohhCarnage Panel Extension, uses an API at https://extensions.cohhilition.com/ and a socket at wss://extensions.cohhilition.com/
  • Dropped Frames video Extension, no API or socket at all, but images from a CDN, usually Twitter/Twitch avatars directly from Twitter/Twitch over HTTPs, it receives from Twitch PubSub only.

You can see that they all all work over endpoints/routes protected by SSL.

We’ll cover how to build a “custom” EBS, and verifying identity in a future post, this week it’s just “Architecture”, the long and short of it, is you are basically just building a Custom API to interact between your front end and backend. A common way I describe Extensions, is as follows

Extensions are a website, where the front end is on a different server to the backend, and you can’t do server side rendering

– Barry Carlyon on “Well what is an Extension anyway!”

Languages

Whilst a Twitch extension is “limited” to HTML and JavaScript, your EBS/Backend API can be in any language you want. But when it comes to examples, samples and boilerplates you’ll generally find them in JavaScript (via NodeJS) or Go, (since Twitch is a “Go House”). We’ll be using NodeJS in this series, merely because it’s potentially the easiest for people to understand and convert knowledge between different languages.

If you want to jump ahead, you can check out the Developer Rig, which will provide you access to a number of Extension Examples, which are also available on the TwitchDev GitHub, or my own Twitch Profile Extension (which demonstrates how to call the Twitch API via an “EBS” proxy), these examples are designed to highlight a specific function of Twitch Extensions, rather than a “practical” example.

Real Certificates only

Naturally this needs to use “real” SSL Certificates, as apposed to self signed, which is “bearable” for testing with. Generally you’ll find Extension Developers will whip out LetsEncrypt as it’s free and easy to setup, and straightforward to setup a testing system.

Summary

So that covers the Architecture of an Extension

Not really sure what else to add, here is a photo of my cat, Sprite.

Sprite has invaded this Blog Post

What about next week?

Next week we will be looking at the Developer Rig and how/when to use it and setting up a Dev environment suitable for developing a Twitch Extension!

BUT MOTHER I CRAVE VIOLENCE

Well, until I write the next part if you want to read more about the Developer Side of Extensions, you can pop a visit over the to the Documentation or take a look at Twitch’s Introductory Page and you can always join us on the “TwitchDev Discord Server”, visit the Developer Support Page for the current invite link!

Why you think you are good enough to even write blog posts on Extensions? I made a one or two of them Extensions of various types.

Twitch Extensions: Part 2 – Integration Points

Welcome to part two of the Twitch Extension Series of Posts.

This week, we’ll be talking a little on Integration Points!

What integration points does a Twitch Extension have?

We touched on this in Part 1

Twitch provides developers with three main, two auxiliary, and two Broadcaster only integration points, and of these integration points Twitch lets us pick the HTML (and thus Javascript or CSS) file(s) we wish to load for all of these. (Well except Panel Popout, screw that guy, it owes me a tenner).

Hang on just a minute

What? OH! You want to know how to create an Extension first or where to set the HTML to be loaded for each view? Yes, that would make a little more sense, wouldn’t it!

Extensions can be created, configured, and release via the Twitch Developer Console.

The Developer console can be found at https://dev.twitch.tv/console

After logging in you’ll generally land on the Summary page that will list you current Extensions, Applications and any Games/Categories you may “own” on Twitch from being part of an organization

An example of the Twitch Developer Dashboard Overview
An example of the Twitch Developer Dashboard Overview

We’ll ignore everything else since we are only interested in Extensions.

Twitch Developer Console for Extensions
Twitch Developer Console for Extensions

If you click Extensions then “Create Extension” it’ll take you through a short “Setup Wizard” before presenting you with your ClientID for the Extension. We’ll do that now so we have an Extension to play with during this series!

PRO TIP: After starting the Wizard, please finish the wizard, even if you intend to change everything later.

  • Asks for your Extension Name, then Click Continue
  • Asks you to pick the views/integration points you want, which you can change later
  • Provide a Version number, 0.0.1 will suffice for now
  • Add additional details such as the Extension description and contact details for you
  • Now hit “Create Extension Version”

Twitch will send you an email to verify the provided contact details, so click the link in those email(s).

We’ll cover most of the other fields in a future post, but today we are interested in integration points.

Twitch will now have dropped us on the status page for our Extension

It’s important to note that you cannot use “Twitch” in the name of you Extension, and the name needs to be unique across Extensions and Applications across all of Twitch

So Integration Points?

On the Extension Status page, hit “Asset Hosting”, this will take us to the page to configure our “Extension Views” and what html to load. Twitch will prefill with something sensible, but you can use anything you want

"Asset Hosting" section of a Twitch Extension Console
“Asset Hosting” section of a Twitch Extension Console

At the top is the Testing Base URI, we are going to ignore this for now, but we’ll be covering it next week, when we might actually start building.

Below that comes the section that lets you pick via Checkbox, which views (for the viewer) you wish to enable. And the settings for each view.

Panel

A Panel is rendered below the stream, in the panels section, Broadcasters have “some” control over where a panel extension will appear in relation to the other panels, Twitch liks to jumble things round sometimes, but generally Panel Extensions are pretty sticky and reflect the broadcasters choice.

A panel has the following settings available

  • Panel Viewer Path – the path and file name of the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL
  • Panel Height – a panel extension is fixed Width (318px), but the developer can choose what height to use, ranging from 100px to 500px

A Panel extension, can be popped out (one of the Auxiliary Integration points we mentioned), which will start at 318px wide and the specified height, but the Viewer can then resize this window. It’s something to be aware of when building your extension, and offers the ability to use Responsive design

Video – Fullscreen

A Video Fullscreen extension will cover the whole stream, so the developer and designer can utilize the whole stream. Usually it’s safe to assume that the size is 1920px x 1080px, and you can scale as needed, we’ll cover some ways to handle this in a future post

A video Fullscreen only has one setting, the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL

Mobile

YES, THE CHECKBOXES GO: Panel, Video – Full, Video – Comp, Mobile but the page goes in a different order

The Mobile view is presented to Viewers using a Mobile device in the Twitch App for that device, such as an Apple iPhone, Apple Table, Android phone and so on.

Like Video Fullscreen there is only one option here, the HTML file to load, it is a relative path to the Testing Base URI/final upload URL

Mobile you’ll need to practice Responsive design as dimensions will vary by device and orientation of the device

Video – Component Viewer Path

A video Component roughly works similar to a Panel, but it defaults to being “closed” and can be manually opened by the Viewer by clicking the relevant icon in the “taskbar”, the Taskbar is presented to the viewer on the right of a Live Stream.

The Extensions Taskbar, left is shown a Video Component Extension in the closed state and right is the open state

The following options are available

  • Video Component Viewer Path – the path and file name of the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL
  • Video Component Sizing Parameters – there are a number of options here we’ll cover this more in depth at a future post as it can get fun!

Non Viewer integration Points

That covers all the Viewer intergration points and their options in summary

Next we have the “Broadcaster” Integration points, there are two of them, both have the same available settings, the path and file name of the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL

Configuration view

This is the main/one off configuration view, when a broadcaster first installs your Extension they will be prompted to ask if they want to visit the Configuration page or not. This page is used for one off or infrequent configuration

The Extension Config prompt during install
The Extension Config prompt during install

In some cases, developers can also block an extension being activated if the configuration has not been done, usually this would be used for things such as providing an API key to access another API, or asking the broadcaster what their Destiny 2/other game Character name is (for example)

The Twitch Extension configuration page for FlightSimTrack
The Twitch Extension configuration page for FlightSimTrack, this example provides additional setup instructions and the API Access Key for the Companion Desktop App

It can be reached from the install flow for an extension and from the “Cog” Icon on an Extension in the Extension Manager section of the Dashboard

In terms of Dimensions it’s usually Landscape but a broadcaster can resize it pretty narrow, so you’ll need to be responsive or provide a minimum width

Live Configuration View

The Live configration view is to be used by the broadcaster for common tasks or things that need to be done during a Stream, examples of this would be to start a Poll for a poll extension, or a “I’m starting a round” in a mini games extension.

The Live configuration view is reached by the Broadcaster from the “Quick Actions” Section of their “Stream Manager”

A Twitch Dashboard Quick Action Button
An example of a Quick Action Extension Button

When clicked, a new window will open, which will contain the Quick Action/Live Configuration View, it’s resizable by the broadcaster so you’ll need to practice responsive design again here

An Opened Quick Action
EliteTrack’s Quick Action view provides easy access to a summary of the data sent, and prompts the user about Bug Reporting

Summary

And that covers the various integration points in a bit more depth compared to last weeks post!

Next week, we’ll be covering “Getting Started Building” I think and why every time I mention a HTML file did I follow it with: “the path and file name of the HTML file you wish to load, it is a relative path to the Testing Base URI/final upload URL”
