Get PortalId when creating AccessToken
I'm working with webhooks that work with different clients. And so each client has their own access token.
Now when I have a client create a Contact, I only get the objectId of the contact that was created, so I need that client's accessToken to retrieve the correct data for that contact.
But in the webhook I don't know which client created it.
If portalId is the determining factor, how would I know when that client created their access token that they correspond to that portalId?
