API Key Rotation Guide
Rotate API keys with inventory, staged rollout, logging, rollback and safe secret handling. This Formalint reference is designed for developers, DBAs, platform engineers and support teams who need an ordered troubleshooting path.
The page keeps the work practical: collect evidence, avoid leaking secrets, make the smallest safe change and leave a note another engineer can repeat.
When to use it
- A deployment, policy, incident or integration behaves differently than expected.
- You need a repeatable command or checklist before changing production behavior.
- You want to keep the debugging note understandable for another engineer.
Practical workflow
| Step | What to verify |
|---|---|
| Inventory the boundary | Name the browser, API, cookie, token, dependency or domain boundary that is affected. |
| Collect safe evidence | Redact secrets before sharing headers, logs, payloads or dependency output. |
| Roll out gradually | Prefer report-only, staged keys, feature flags or small blast-radius changes before enforcement. |

- Write down the affected host, endpoint, job, service or browser context.
- Redact tokens, session cookies, passwords and customer identifiers.
- Capture timestamps, headers, logs or command output before changing settings.
- Prefer staged rollout, report-only mode, preview checks or single-URL cache purges where possible.
- Link the final note to a related Formalint page so the next step is obvious.
Common mistake
The common mistake is weakening a policy permanently to fix one symptom instead of collecting the violation and narrowing the exception.
Formalint's rule for these areas is simple: make the hidden system boundary visible before you tune it.

Frequently asked questions
Is this page enough for production approval?
No. Use it as a diagnostic and review aid, then follow your team's release, security and compliance process.
Can I paste real secrets or logs here?
No. Keep secrets and customer data out of browser tools. Use redacted examples and preserve sensitive evidence only in approved internal systems.
