How to Rotate API Keys Without Downtime

Formatos de comunicaciónEN2026-10-25

A safe API key rotation separates two events: moving applications to a replacement credential and revoking the previous one. This walkthrough uses an overlap window so you can validate the replacement before removing the working key. The same sequence appears in AWS guidance for rotating long-lived credentials without interruption. ([aws.amazon.com](https://aws.amazon.com/blogs/security/how-to-rotate-access-keys-for-iam-users/?utm_source=openai))

§ 1. Confirm that overlapping keys are supported

Before changing production, confirm that your account can hold two independently valid API keys and that creating one does not invalidate another. This walkthrough assumes that capability; it does not assume a particular Vana API dashboard control or rotation endpoint. If overlapping credentials are unavailable, arrange a supported migration method before proceeding.

For an OpenAI-compatible Vana API client, keep the existing base URL unchanged during rotation. The documented OpenAI-style address is https://api.vanaapi.com/v1. Change the credential separately from routing so the test isolates authentication. If you are starting fresh, create a Vana API account before preparing your first deployment.

§ 2. Inventory every consumer

Build a checklist of everything that uses the current key. Include production services, background workers, scheduled jobs, deployment pipelines, local development environments, and command-line tools. Record where each consumer obtains its secret and how you will confirm its migration.

Owner: who can deploy or restart the consumer.
Secret reference: the configuration entry or secret-manager path.
Reload method: rolling restart, client reconstruction, or a tested refresh mechanism.
Verification: a successful request attributable to the replacement configuration.

Include infrequent jobs explicitly rather than waiting for normal traffic to reveal them. Use this inventory as your revocation checklist.

§ 3. Create and store the replacement

Create the replacement through the supported account interface. Store it as a separate version in your secret manager, leaving the current production version available during the migration. Restrict access to the workloads and operators that need it. Centralized storage, controlled access, and a defined rotation lifecycle follow OWASP secrets-management guidance. ([cheatsheetseries.owasp.org](https://cheatsheetseries.owasp.org/cheatsheets/Secrets_Management_Cheat_Sheet.html?utm_source=openai))

Assign a nonsecret deployment label, such as rotation-2026-10. Use that label in deployment records and telemetry rather than recording the credential itself. Exclude API keys and authorization headers from logs, screenshots, and support tickets. OWASP logging guidance specifically identifies access tokens and other secrets as data to exclude. ([cheatsheetseries.owasp.org](https://cheatsheetseries.owasp.org/cheatsheets/Logging_Cheat_Sheet.html?utm_source=openai))

§ 4. Test one consumer first

Configure a staging instance or one production canary to use the replacement. Keep its existing endpoint, protocol, model selection, and request settings unchanged. Send a small representative request, then exercise the response path your application actually uses, including streaming if applicable.

Set explicit acceptance criteria: successful authentication, a complete response, and application-level checks passing. Do not treat a successful deployment or a healthy process as proof that an authenticated API request works.

§ 5. Roll out without dropping active work

Promote the replacement secret version and update consumers in small batches. Require each new instance to pass readiness checks before retiring its predecessor. Configure graceful shutdown and allow active work to drain.

Check how your runtime reads credentials. In Kubernetes, updating a Secret does not update an environment variable inside an already running container; the container must restart to receive the new value. Plan a rolling replacement instead of assuming that a secret update refreshes every process. ([kubernetes.io](https://kubernetes.io/docs/tasks/inject-data-application/distribute-credentials-secure/?trk=public_post_comment-text&utm_source=openai))

Keep the previous key valid throughout the rollout. If validation fails, stop the migration and restore the previous configuration while investigating.

§ 6. Verify coverage, then revoke

Check every inventory entry. Run scheduled jobs deliberately where practical, and verify that newly started workers receive the replacement. Before revocation, require evidence that all consumers have migrated and active work using the previous configuration has finished.

Revoke the previous key through the supported interface. Repeat representative requests and monitor authentication failures. Remove obsolete secret versions according to your retention policy, and record the completion date and owner.

For suspected compromise, use an incident-response procedure instead. Do not extend the overlap window simply to preserve convenience: OWASP recommends prompt revocation and replacement of compromised secrets.
