   A company uses Dataverse as its system of record. A custom connector in an external system needs to receive a notification whenever a high-priority support case is created. The solution must not require the external system to poll Dataverse, and the notification must be delivered reliably even if the external system is temporarily offline. You need to design the integration. What should you do?

   • ARegister a webhook service endpoint and use the IServiceEndpointNotificationService in a plug-in to post the case creation event to the webhook.
   • BConfigure a Power Automate flow with a Dataverse trigger and use the 'Send an HTTP request' action to call the external system.
   • CUse the Plug-in Registration Tool to register a step on the Create message and set the delivery mode to 'Async' without configuring a service endpoint.
   • DCreate a custom API that the external system calls every minute to query for new high-priority cases.

   • AUse a custom plug-in to add the header to the HTTP request.
   • BUse HttpQueryString authentication and append the header as a query parameter.
   • CUse the WebhookKey authentication and set the key value; the header name is always 'X-Function-Key'.

   A company uses Dataverse and needs to send real-time notifications to an external application when a new invoice is created. The external application is a modern web service that exposes an HTTPS endpoint.

   • ARegister an Azure Service Bus queue and have the external application poll the queue.
   • BRegister a webhook service endpoint and register a step on the Create message of the Invoice entity.
   • CCreate a Power Automate flow with a Dataverse trigger and use the 'Send an HTTP request' action.
   • DUse the IServiceEndpointNotificationService in a plug-in to send an email to the external application.
