Zapier users are trying to setup Webhooks with Smartsheet and receiving HTTP 403 on this call
PUT https://api.smartsheet.com/2.0/webhooks/<scope> (to enable the webhook)
Request data is {"enabled":true}
Example response data is { "errorCode" : 1004, "message" : "You are not authorized to perform this action.", "refId" : "xopb9p"}
Prior to this call the user is able to successfully:
GET https://api.smartsheet.com/2.0/webhooks (to list webhooks)
POST https://api.smartsheet.com/2.0/webhooks (to create the webhook)
All these calls require the same ADMIN_WEBHOOKS OAuth scope, which we have enabled.
The errors only began on July 7, and now 80% of these PUT calls are failing with this error.
Please reach out via email if any sensitive details are required, otherwise I will monitor this thread.
Thank you.
