API Key Authentication

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. Just include it in the Secret-Key header or secret_key query param and you should be good to go!

🚧
Do not include your Private API Key on your storefront.
Your Private API Key gives access to all your store's data, including customer data. Never include it in your site's HTML, JavaScript or CSS code.
Instead, consider using the Public API.
