Editorial draft available to read. Factual and language review is pending. Examples are illustrative.
Decision and method
Inventory the current connector's operations, formats, permissions and assumptions. Compare documentation for both versions and classify changes to fields, behavior and errors. Prepare contract tests and a transition with an owner, advancement criteria and recovery plan. Merely changing an endpoint address does not establish functional compatibility with the existing workflow.
Illustrative example
Illustrative example: a new version replaces one status field with two fields and changes pagination. Testing checks interpretation and retrieval of every record, including an incomplete final page. The rehearsal uses fictional data and avoids executing external actions twice while results from the old and new versions are compared.
Acceptance check
Run ordinary and failure cases before switching, then compare results with evidence. Define what happens if returning to the previous version is no longer available. Accept the transition when critical requirements have no unexplained differences and the team has monitoring, reconciliation and an incident procedure covering the changed integration behavior.
Key takeaways
- Validate an API migration through behavior and results rather than successful connection alone.
