How to Protect API Integrations From Clock Skew in Signed Requests

11/10/2026

Signed requests may fail when client and server clocks differ beyond the provider’s accepted window.

Checks to make

Compare system time with a trusted time source, inspect signature timestamps and provider errors, and confirm timezone handling does not alter epoch values. Monitor clock synchronization and test requests after correction without exposing signing secrets.

When to get help

API engineering can review signing, timestamp, and time synchronization. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
