How to use private and public API access keys generated via the mobile APP


I have created a public and secret key for the API via the app. I can’t see anywhere in the api documentation where these keys can be used to access the API.

Please can you point me to how I can submit these keys and make an api request. I can’t see it in the docs here:

It describes access via a token on this page but not access with keys.

Thanks in advance.
