#  API credentials Management

<Accordion title="How to generate and view API credentials in the portal?">
  To access them, go into the tab "Authentication" in the developer portal. There, you will find your Sandbox accesses.
</Accordion>

<Accordion title="What information is required to request API access?">
  To authenticate to the Business API with your Qonto account, you have 2 options depending on the endpoints you will be calling: using Api key or OAuth 2.0.

  [Here](https://docs.qonto.com/get-started/business-api/authentication/introduction#endpoints-access) is a recap of all endpoints and accesses.
</Accordion>

<Accordion title="How do I refresh my OAuth client_secret for the Business API?">
  In the developer portal, go to **Authentication → Business API → OAuth 2.0** (use the **Sandbox / Production** toggle for the right environment), then click the **refresh icon** next to the Client secret.

  Regenerating **immediately invalidates the previous secret**, so update your integration with the new value right away. Your `client_secret` does not change on its own — it only changes when you regenerate it here.
</Accordion>
