A practical example
Example: a purchase webhook is retried by the payment provider after a network timeout.
A deduplication rule keyed on the transaction ID processes the first delivery and discards the retry, so the customer receives one receipt instead of two.
What to evaluate before investing
- Ask what the deduplication key is: event ID, transaction ID, or a combination of fields, and whether you can define it.
- Check the deduplication window: how long the platform remembers prior events.
- Confirm whether duplicates are dropped silently or logged for audit.
Limitations and tradeoffs
Tradeoff: an overly broad deduplication key can discard legitimate repeat events, such as a customer's second genuine purchase with the same product.
