I Lost 6 Hours to a Stripe API Change. So I Built Something to Stop It Forever.

Description and use

API Sync Agent automatically detects API changes, scans code, and generates fix PRs, eliminating manual changelog reading and reducing downtime.

Problem

A minor Stripe API update caused production downtime, leading to 6 hours of debugging and client frustration, highlighting the broader issue of unnoticed breaking changes in external APIs.

Outcome

The tool prevented future downtime by automating detection and remediation of API changes, saving developers hours of debugging.

Workflow

• 1. Deploy API Sync Agent to monitor target APIs 24/7.
• 2. Agent detects a breaking change in Stripe’s API.
• 3. Agent scans the codebase for affected calls.
• 4. Agent generates a pull request with suggested fixes.
• 5. Developer reviews and merges the PR.
• 6. System confirms the fix and resumes normal operation.

Evidence

6 hours of debugging. 3 cups of coffee. 1 very angry client.
