## [FAQ](#faq)

How do I get my API credentials?

Create an account on the portal, then go to **[My Applications](https://api-portal-suitelogi-quaext.stef.com/apps)** to create an application. Your **Application Secret** is displayed at creation — copy it and keep it in a safe place. Once the application is approved, you can use it in your calls. See the [getting started guide](https://api-portal-suitelogi-quaext.stef.com/en/getting-started) for more details.

What is the difference between Sandbox and Production?

The **Sandbox** environment (`https://sandbox-api.stef.com`) is dedicated to testing — no quotas, fictitious data. The **Production** environment (`https://api.stef.com`) uses real data with the quotas defined in your access plan.

My token has expired, what should I do?

OAuth 2.0 tokens expire after 1 hour. Request a new token via the `/oauth2/token` endpoint. We recommend implementing an automatic renewal mechanism (refresh token). See the [authentication guide](https://api-portal-suitelogi-quaext.stef.com/en/getting-started/authentication).

Error 429 — Too many requests

You have reached the request limit of your plan. Check the `X-RateLimit-Remaining` and `Retry-After` headers in the response and implement exponential backoff. See the [best practices](https://api-portal-suitelogi-quaext.stef.com/en/guides/best-practices) for rate limiting management.

How do I test an API without writing code?

Each API has a **Try it** mode on its documentation page on this portal. You can also export the OpenAPI specification and import it into [Insomnia](https://insomnia.rest/) or Postman using the dedicated button.
