Webhooks

[RodneyH1]

Trying to get webhooks set up for course changes. . .documentation is a bit slim, so I'm trying to get the steps down.

1)  Contact Canvas to get a profile setup against my dev key ( https://canvas.instructure.com/doc/api/file.jwt_access_tokens.html)

Note: to retrieve a custom Tool Consumer Profile an Instructure employee must first create the tool consumer profile and associate it with your developer key. Please contact us for assistance with this process.

2)  Use that profileId to pull a JWT token

3)  Use that JWT token to call the necessary /api/lti/subscriptions endpoints

But. . .for (3). . .should the POST (to make new webhooks) have the info passed as params, or as a body object?

We tried to use webhooks to subscribe student quiz submission events. The institution canvas manager has helped us with development key and its associated client ID. However we got the error: {"error":"invalid_grant"} and don't know how to resolve that. Could you advise who we should contact?
