Authenticate your API calls before making API calls. The Invoice API uses JSON web tokens (JWT) for authentication. To generate a token for accessing the API, you need to make use of your generated API KEY. All API calls requires a token for authentication.

Your token is the value of "token" in the json response. This must be included as an Authorization header in all subsequent requests.

An access token will expire in the time defined by expiry in the response from Authentication. If a token has expired you will need to refresh it using the current refresh_token to generate a new access token.

Once this is done the previous access token is invalidated.
