# API subscription checklist

> Use this checklist before subscribing to an API for production use, including pricing, limits, support, security, and integration readiness.

# API subscription checklist

Before you move an API subscription into production, confirm that the service, billing terms, and integration path match your application requirements.

## Subscription details

* Confirm the included usage, overage rules, renewal period, and cancellation terms.
* Check whether failed requests, retries, or rate-limited requests can affect billing.
* Save the plan details in your internal documentation.

## Integration readiness

* Test authentication with a non-production key.
* Run basic success, error, and rate-limit scenarios.
* Confirm the API returns errors your application can handle.
* Add logs that connect API calls to user actions or internal jobs.

## Security review

* Store keys in environment variables or a secret manager.
* Limit who can create, view, and rotate keys.
* Rotate keys when team access changes.
* Review [Security and privacy](/security-and-privacy) before production traffic.
