How to set up the Twitch Extension

Step 0: Prerequisites

In order to use the extension, you will need the following:

  • Your own Twitch Channel
  • A Microsoft Windows device, which can run MTG Arena and the Untapped.gg Companion at the same time
  • A free Untapped.gg account. You can create it at https://accounts.untapped.gg/create

Step 1: Download the Untapped.gg Companion

You can download the Untapped.gg Companion here. If you already have it installed, skip this step.

Step 2: Install the Twitch Extension

a. Go to your Creator Dashboard on Twitch, click on the 'Extensions' tab on the left, and search for 'Untapped.gg'.

b. Click on the '+ Install' button in the top right corner.

c. Click on the 'Configure' button in the popup. If you've accidentally closed the popup don't worry - you can just return to the extension page above and will find the 'Configure' button where the 'Install' button was previously located.

Step 3: Retrieve your Extension Key

a. Leave your browser open, and start the Untapped.gg Companion and connect your account. If you don't have an Untapped.gg account, you can create one here.

If you've already connected your Untapped.gg account with the Companion, proceed to the next screenshot:

b. Once your account is connected, click on the MTG Arena tab in the left menu:

c. Scroll to the Recording and Streaming section and click on the 'Setup Twitch Extension' button:

d. In the popup, click on 'Enable Twitch Extension':

e. Click on 'Copy to Clipboard' to copy the Extension Key.

Step 4: Insert Extension Key on Twitch

Return to your browser, and paste the Extension Key in the box.
If you've accidentally closed your browser, you can also click the link in the Companion below the 'Copy to Clipboard' button to return to the extension page, where you will find the 'Configure' button.

Step 5: Activate the Twitch Extension

You're nearly there! Now all you need to do is activate your new extension.

  • Go to the Extensions tab on your Creator Dashboard.
  • Click on 'My Extensions'.
  • Select the 'Untapped.gg for MTGA' extension, click on 'Activate' and 'Set as Overlay 1'.

That's it, you're all set!

At this point, the extension should appear on your channel whenever you're playing MTGA with the Untapped.gg Companion running.

If something is not working, return to the Twitch Extension Setup in the Untapped.gg Companion (under 'MTG Arena'). All items must be green for the extension to work. If you just went live, it may take a few minutes for Twitch to notify the companion that you're online.
