# Authentication

> Authenticate to the Onboarding Partners API with your Bearer token and your Qonto-Partner-Id.

In order to authenticate, you need to get your credentials by signing up to the [Developer Portal](https://developers.qonto.com/) (for more details on the process cf. [Get started](https://docs.qonto.com/guides/developer-portal/developer-guidelines.md)).

For each API call, you will need to include those credentials in the following headers:

| Header | Value |
| - | - |
| Authorization | Bearer `token` |
| Qonto-Partner-Id | `partner_id` |

Only in the Sandbox environment, you will also need to provide the following header:

| Header | Value |
| - | - |
| X-Qonto-Staging-Token | `staging_token` |

> [!TIP]
>
> The `X-Qonto-Staging-Token` header bypasses the OneLogin gate that protects our Sandbox environment for **API calls only**. If you also need to open the `redirection_link` returned by [Create a registration](https://docs.qonto.com/api-reference/onboarding-api/endpoints/registrations/create-a-registration.md) in a browser, you have to bypass the gate a different way — see [Accessing the Sandbox environment](https://docs.qonto.com/guides/developer-portal/sandbox-access.md).

> [!NOTE]
>
> The Onboarding Partners API has no API key and no OAuth scopes: every endpoint uses these headers. Each endpoint page reminds them right below its method and URL.
