error trying to creating webhook smartsheet


Only URLs with a protocol of 'https' are supported for attribute 'callbackUrl'

Solution

  • This error message means exactly what it says: the value that you specify for the callbackUrl property in the Create Webhook request must begin with https:. If the value you specify for the callbackUrl property begins with http: then you'll receive this error message in response. This restriction is in place for security reasons -- i.e., Smartsheet will only send webhook notifications to secure endpoints.
