Hi Lara. You can automatically add users to specific group(s) inside your community if the user has a specific differentiator on his/her account. 

The differentiator can be something like: user's payment plan on your website, country, language, role, or any other information that you have from your side on the user's accounts. 

Then, you can use Tribe Webhooks to tell Tribe if the user has the differentiator that you have defined.

Then, use the Zapier to automatically add the user to a certain groups in the community. 

You can access our Webhooks here3. The Webhook you need to use is "user.signup". 

If you are worried about removing users from those groups when the user is not eligible (for example the user is not on your paid plan anymore), you have 2 ways to automatically remove the person from the group:
_Use an API to update the paid member's list (this should be done by your tech team from your end).

_Or to use the Stripes's webhook (or any other payment software's webhook that you are suing) to remove the user from a group on Tribe if the payment is canceled.

Hi @Connor Forsyth3 - Thanks! Welcome to Tribe. 🙌

If Memberstack supports SSO, then this can be set up. Otherwise, Zapier integration can be used to create an account on the community automatically.
