When you create an Application, you are assigned a secret API key (see Get an API key chapter).You must first obtain a JSON Web Token (JWT) using this API key.To do this, make a POST request to Get Access Token endpoint with your API key.You must authenticate to our API by providing the JWT in the header of each request. Never share your tokens. Keep them under surveillance and safe.Once the token has expired, you must obtain a new token to continue making authenticated requests.
