Scope an API integration around specific records and operations. Write down what moves, in which direction, and how the teams will know it arrived correctly. This gives engineering and the system owners the same definition of completion.
Identify records, direction, and ownership
Name the source and destination objects and decide which system owns the information. Record the event or schedule that moves it and how a record can be identified on each side. Decide which updates, deletes, or backfills belong in scope. Include an example of a record that should be ignored.
Check access, fields, and service limits
Confirm that a supported API and test environment can perform the needed operation. List the permissions, fields, formats, and documented rate or volume limits that matter. Map required and optional values, including a rule for blank or unknown data. Ask who can change the source schema and how the team will learn about changes.
Agree reconciliation and acceptance
Define how duplicates, timeouts, and invalid items will be handled. Check the destination after a write with an uncertain outcome before retrying. Compare representative source and destination records, including a corrected case and a replay. Agree the report or queue the operator will use to investigate discrepancies.
Example
Define a one-way deal event into a downstream task list with retries and matched counts.
What to do next
Treat identity, permissions, field mapping, and recovery as part of the same integration scope.
