This endpoint lists the payload content types that a webhook can use. Use one of these values in the `contentType` field when you create or update a webhook. The server posts the payload as a JSON body for `application/json`. For `application/x-www-form-urlencoded`, the server makes a string of the payload and posts it as a form under the `payload` key. Note the capital `C` in the `ContentTypes` response field. The order of the values changes between calls.
