Authentication

The API uses an key to authenticate requests.

You must include an API key with every API request. In the following example, replace YOUR_API_KEY with your API key.

If you account is set to invoice. Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code etc.

In order to make a request the API key must be passed with the request as part of the header . Curl example url -X --header 'apiKey: YOUR_API_KEY'

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.
