Integration Without Illusions

HTTP, vendors, retries, idempotency, partial failure, and compatibility at boundaries outside one application's control.

  1. An HTTP 200 Does Not Mean the Operation Succeeded
  2. A Third-Party API Is an Unreliable Collaborator
  3. Validate at the Boundary You Control
  4. Map External Data Before It Enters Your Model
  5. A Webhook Delivery Is Not a Unique Event
  6. An Idempotency Key Is Not an Identity
  7. A Rate Limit Belongs to All the Workers Sharing It
  8. Retry Budgets Multiply Across Layers
  9. Partial Work Needs a Child Ledger
  10. A Cache Must Distinguish Empty from Unavailable
  11. Renaming a Field Is a Protocol Migration
  12. A Capability Interface Is Smaller Than a Vendor Client
