The Business API supports 2 authentication methods: Depending on who will be using your integration and which endpoints you will be calling, you could need to use OAuth 2.0 (instead of the API key).

Which authentication method do I need?

To authenticate to the Business API with your own Qonto account, you have 2 options depending on the endpoints you will be calling (cf. the table below to identify if you need to use an endpoint which is only accessible through OAuth).
Follow those steps.
  • Sign up to the Developer Portal to get your credentials (as well as an access to our Sandbox environment);
  • Implement the OAuth flow.
