Steps
Create an API key scoped to the target group with group read/write permissions, or set up OAuth2 with group:read / group:write scopes for a third-party app
Call the Open Cloud v2 groups endpoint to list current memberships and roleset definitions for the group
Update a member's role with a PATCH request to the membership resource, specifying the new roleset ID
Handle join requests via the accept/decline membership-request endpoints if the group requires approval to join
Manage roleset definitions (create/update/delete) through the rolesets endpoints when the group's role structure itself needs to change
Verify the change took effect by re-fetching the membership resource, since some invalid-permission responses come back with minimal error detail
Known gotchas
The account whose API key or OAuth token is used must itself hold sufficient rank/permission in the group to assign the target role — a key alone isn't enough if the underlying account lacks group authority
Error responses for invalid rank or permission cases are often non-descriptive, so failures can require trial-and-error to diagnose
Legacy groups.roblox.com endpoints are being phased out in favor of Open Cloud v2, so bots built against the old API may need migration
