How to Keep API Data Consistent When Two Systems Update the Same Record

If two connected systems can edit the same record, later updates may overwrite newer information or create conflicting values.

What to check

Identify field ownership, update timestamps, version numbers, conflict behavior, retry logic, and audit history. Test concurrent edits with non-production records.

Recommended next step

Define a source of truth or explicit conflict resolution and retain change history. Informatix Systems can design and troubleshoot custom API integrations.
