How to Handle API Pagination When New Records Arrive During a Sync

11/11/2026

A paginated sync can skip or repeat records if the collection changes while pages are being fetched.

Checks to make

Use provider-supported cursors or stable ordering, persist checkpoints, and deduplicate by stable record ID. Reconcile totals or use a high-water mark, then test inserts and updates during sync before relying on the process.
