Hello, 

I am trying to subscribe a URL (from Zapier) to the groups.MemberJoined webhook event according to the documentation here and am receiving an error message. 

I’m making a POST call to https://api2-us-west-2.insided.com/v2/webhooks/group.MemberJoined/subscriptions and have included my Gainsight credentials as username and secret in the body of my request. I also have a newly generated auth token that I’ve successfully been making other requests with. 

I continue to receive a 403 “forbidden, access denied” error. Would appreciate any guidance!
