Post-Incident Report: October 14, 2025 — Duplicate Payment Executions

Summary

On October 14, 2025, we identified and resolved an issue that caused some payment transactions to process more than once. The problem stemmed from a recent system update intended to improve transaction timestamp accuracy. Once detected, our engineering team quickly mitigated the issue, coordinated with affected partners.

What Happened

During a scheduled deployment, a logic change in our transaction workflow inadvertently caused certain payment requests to re-execute under specific timing conditions. This resulted in a limited number of duplicate payment submissions to downstream gateways.

The incident began around 7:30 AM Pacific Time and was fully contained by approximately 1:30 PM. No cardholder data, credentials, or security systems were impacted at any point.

How We Responded

As soon as the anomaly was detected, our engineers initiated our critical-incident response protocol. We identified the root cause within hours, implemented and validated a fix across all environments, and are working directly with partners and merchants to reverse any duplicate charges.

We also continued post-incident data validation to ensure no residual effects and to confirm transaction integrity across all systems.

What We’re Doing to Prevent It

We’ve taken several steps to make sure this doesn’t happen again:

  • We’ve added extra checks that automatically spot if a transaction ever tries to process more than once.
  • We’ve improved our testing so that changes to our systems are caught earlier—before they go live.
  • We’ve made our internal documentation clearer so teams can easily understand how each part of the payment process works together.
  • We’ve expanded our monitoring tools to catch unusual behavior faster and respond right away.

Our Commitment

At Authvia, reliability and trust are foundational to every payment we power. We are deeply committed to transparency, fast resolution, and continuous improvement. We thank our partners and merchants for their patience and trust as we worked through this issue swiftly and thoroughly.
