A plug-in on the opportunity table must post the execution context to an Azure Service Bus queue already registered as a service endpoint, but only when the estimated revenue exceeds a threshold stored in an environment variable. The team wants the platform's own posting mechanism rather than custom HTTP calls. How should the developer implement this?

An Azure-aware custom plug-in obtains IServiceEndpointNotificationService from the service provider and calls its Execute method with an EntityReference to the registered service endpoint and the current execution context. Because the call happens inside plug-in code, the plug-in can first read the environment variable, compare it with the estimated revenue, and post only when the condition is true. The asynchronous service then performs the post as a system job, so status and retries are visible like any other posting. A step registered directly on the service endpoint posts every time the message fires; filtering attributes restrict an Update step to changes in specific columns and cannot evaluate a value against a threshold. Sending JSON through HttpClient with a connection string bypasses the platform's posting, puts secrets in plug-in code, and loses the remote execution context format and system job tracking. IOrganizationService executes Dataverse messages; there is no organization request that posts to a service endpoint by name. Exam caveat: register the plug-in step asynchronously for best performance unless the caller truly needs the post inside the transaction. Operational check: update one opportunity above and one below the threshold and confirm only one message arrives on the queue.
