Asset Processor Submission Notice

The LTI Asset Processor Submission Notice is a Notice that can be configured via the Platform Notification Service [[lti-pns]] and are sent directly from a platform to a tool (not via a user's browser). The event by which this notice is triggered, is a user submitting one or multiple assets (files) to a platform activity where an asset processor is attached. A platform MUST NOT send LTI asset processor submission notices for submissions made to activities where an asset processor is not attached. An LTI Asset Processor can be uniquely identified by a combination of the following properties: Activity.Id and custom data properties.
