 ## Provider configuration
 
 The provider needs to be configured with the proper credentials before it can be used. Requests to OVHcloud APIs require a set of secrets keys and the definition of the API end point. See [First Steps with the API](https://docs.ovh.com/gb/en/customer/first-steps-with-ovh-api/) (or the French version, [Premiers pas avec les API OVHcloud](https://docs.ovh.com/fr/api/api-premiers-pas/)) for a detailed explanation.

-- OAuth2, using scopped service accounts, and compatible with OVHcloud IAM
-- application key & application secret & consumer key

 The required keys are the `application_key`, the `application_secret`, and the `consumer_key`.
