What are webhooks, and when are they useful?

Understand the working context

The sender delivers a message to a configured endpoint. The receiver must understand the event, validate it and decide what work to do. Delivery and successful business processing are different things: receiving a message does not prove that the intended downstream action completed. A receiving service should also account for repeated deliveries so that retrying a request does not create the same task or transaction again.

Put it into practice

• Choose an event that the sending service actually supports.
• Confirm what information the receiver needs.
• Validate the sender and handle repeat deliveries deliberately.
• Review failures and retry behaviour before depending on the workflow.

A practical example

A supported CRM event could notify an external service that a record changed. The receiver checks the event and decides whether to update a separate workflow. Both systems need a clear agreement about identifiers and what counts as successful handling. The exact available events depend on the product.
