Knowledge Base & Operational DocumentationHow to Prevent an API Integration From Sending the Same Update Repeatedly
An integration can repeatedly send the same update when a webhook is retried, acknowledgments are delayed, or the sender cannot distinguish a completed event from an unprocessed one. Duplicate writes can trigger repeated notifications or downstream work.
What to check
Trace event identifiers and delivery attempts across both systems, review retry timing and response handling, and check whether the destination supports idempotency keys. Determine if duplicates occur after timeouts, restarts, or partial failures.
Recommended next step
Store processed event identifiers durably and make updates idempotent where possible. Define bounded retries and a reconciliation path for ambiguous outcomes, then test duplicate and delayed delivery in a safe environment.
How Informatix Systems can help
Informatix Systems provides custom software and API integration services. We can review the affected systems and workflow, help narrow down the cause, and outline a practical implementation path. Contact us with the platform involved, when the issue began, and non-sensitive error details.
