Push a Product Update Notification

Function

After the application calls the API for creating a rule triggering condition (resource is set to product and event to update), the API for creating a rule action, and the API for modifying a rule triggering condition, and activates a rule, the platform pushes the result to the server specified by the rule when the product is updated.

URI

POST /HTTP URL determined when the application creates the product update notification rule. The AMQP channel does not require the URL.
