This article explains how to grant Tymber access to your Google Tag Manager account.
From your Tag Manager account, go into the "Admin" tab and select "User Management".
When in User Management, you'll see a plus sign to add new users.
From here, you'll input the email address of the user you want to add and adjust the account permission settings. To grant Tymber access, please add seo@tymber.io as the new user.
Now, you'll edit the permissions. Be sure to select the box for 'administrator'. At the bottom, notice the container permissions only allow the new user to 'read' the containers. Tymber needs the ability to fully edit and publish. Select the button that says 'set all'.
Now, select all the permissions to read, edit, approve, and publish. You'll hit done and send the invitation. Once Tymber accepts the invitation, then we'll have access to your account and be able to connect it to your site.
