Confirm the transport service and background-process capability are available on the plan. Identify the receiver names, production environment and appropriate worker account.

1. Configure the transport and route the intended message classes to it. Keep credentials private and create the required transport resources through the approved deployment procedure.

2. Send a test message with a harmless outcome. Verify which receiver contains it before starting a consumer.

3. Run messenger:consume for the intended receiver under an approved supervisor, with time or memory limits that fit the account. Allow the supervisor to replace workers when they exit.

4. Configure retry and failure transport behavior deliberately. Make handlers tolerate redelivery so an uncertain result does not create duplicate invoices, emails or external actions.

5. During deployment, stop old consumers gracefully using the supported Messenger command and let the supervisor start the new release. Confirm workers do not remain attached to obsolete code.

Check that a queued message completes, a controlled failure reaches the expected failure handling and the consumer returns after a restart. Monitor waiting time as well as process status.

If the queue grows, compare the transport configuration and receiver name used by the sender and consumer. Investigate the message exception before mass retrying failed work.
