API update illustration On January 5, 2026, timestamps returned across all Argyle endpoints and webhooks will be standardized to a single, uniform format, with any fields that currently use microsecond precision updated to millisecond precision:
  • ISO-8601 with millisecond precision (3-digit fractional seconds)
  • Example: YYYY-MM-DDTHH:MM:SS.mmmZ
This update requires no action for most integrations, but if you are validating timestamps with strict schemas or fixed-length parsing, please make any necessary adjustments before January 5. For assistance, contact your Argyle customer success manager.
