Webhooks for FDEs

Quick answer

Event callbacks that a partner system sends to you. Partners retry, reorder and duplicate events; an FDE has to make the receiving side safe.

Practise it

  1. 1. Build a receiver that verifies signatures
  2. 2. Make a handler idempotent
  3. 3. Replay a failed event from a log

Where it sits

Stage 2 of the roadmap: Data and APIs. You can move data between two systems and keep it correct.
