If you're a merchant or developer working on behalf of a merchant, then you should be using API Key authentication.
You can find your secret key in your account from here.
To access the API you can put your secret key in the
Secret-Key header, or you can include it in the URL params with each request as
Keep your secret key, secret!
Don't give out your secret key to anyone or reveal it to your customers. If you're looking to build front-end customizations use Fera.js instead which only requires the public api key.
