Most MARCO API endpoints are protected using Bearer Authentication. Before using the API, you need to obtain an AccessToken with the required scopes in combination with an ApplicationToken in the request headers to identify the application using the API.


To obtain the access and application tokens, follow the steps in the Get your API tokens guide.

Once you have the tokens, you can use them to authenticate your requests. For example, to call the GET /marpps/marpps/featured endpoint, you must include the following headers:

curl --location --request GET '' \
--header 'Accept: application/json' \
--header 'ApplicationToken: <APPLICATION_TOKEN>'\
--header 'Authorization: Bearer <ACCESS_TOKEN>'
