The documentation at https://developer.shotgunsoftware.com/3d448f5e/ says
Included in those headers is the ID of the delivery record, stored in the
x-sg-delivery-id
key. This id can be used to update the delivery record to include an acknowledgement using the Shotgun REST API
However https://developer.shotgunsoftware.com/rest-api/#shotgun-rest-api-Access-Webhooks doesn’t have any info about webhooks acknowledgement payload. I understand this is because the feature is in beta.
Could someone please shed light on the recommended payload and the endpoint I should be posting to?
