How it works

How to get started with the API

  1. Create an OAuth2 application

    In your account, specify the redirect URI and scopes for your integration.

  2. Obtain an access token

    Complete the OAuth2 flow on the account domain and obtain a Bearer token for requests.

  3. Call the REST API

    Send requests to the API domain with the Authorization: Bearer header. See Redoc for details.
