Authentication
GroupMe OAuth application client ID for obtaining user access tokens oauth2 discovered Set up OAuth ↗
X-Access-Token: <credential>

Sign in at GroupMe Developers with your GroupMe account, then create an application from Applications. The auth guide says you can get a client ID from Create Application. Send users to https://oauth.groupme.com/oauth/authorize?client_id=CLIENT_ID; after the user approves, GroupMe redirects to your registered HTTPS callback URL with access_token in the URL fragment/query as documented. Use that access token in the X-Access-Token header for API calls.
