How to Detect When an API Pagination Change Truncates Imported Records

An integration can return HTTP success for every request and still import only part of a dataset if pagination behavior changes. Page size limits, cursor formats, sorting, or snapshot semantics may differ after an API update.

Track the complete extraction

Record each request cursor, response count, next-page indicator, and final source total where available. Compare the imported record count with the provider's reporting view for the same time and filter. Check whether new records arriving during pagination shift the result set.

• Follow documented cursor or continuation tokens until completion.
• Use stable sorting and overlap windows when the API supports it.
• Deduplicate by source record ID.
• Alert when counts or pages fall outside expected ranges.
