Payload Correlation

A practical example

Example: your platform sends a lead's email to an enrichment service and receives the result via webhook minutes later.

A correlation ID embedded in both messages lets the listener attach the returned job title to the correct lead instead of guessing.

What to evaluate before investing

• Ask whether the platform lets you inject a custom identifier into outbound requests and read it back in responses.
• Check how the system handles responses that arrive without a matching ID: are they logged, quarantined or discarded?
• Confirm that correlation IDs are unique per request and persist long enough for slow responses.

Limitations and tradeoffs

Correlation only links messages; it does not prevent duplicates. A repeated response with the same ID still needs separate duplicate handling at the receiver.
