Ask HN: How do you test payment webhook edge cases?

    proxy that does all of the above rather than mocks. we had configurable one based on txid.

    ex: tx uuid fe83dd01-aaaa-aaaa-aaaa-000000005373 if chunk1 is aaaa, then treat last bit as 'delay for 5373ms'

      Clever approach — encoding the behavior in the txid itself.

      Did you have a UI to configure scenarios, or was it all code-based? And did you simulate webhook failures/retries too, or just delays?

        it was code base. first chunk would be git revision-sha . failure, retry, delay, multiple replay due to retry timeout (idempotence test)

          Makes sense — idempotence testing is a great use case. We've hit bugs where retries created duplicate charges.

          If this existed as a hosted tool with a UI to configure scenarios (instead of encoding in txids), would that have saved you time? Or was code-based actually preferred?

            dont care would never have used hosted.
