# Nutrition-API

To begin, you will need your <mark style="color:red;">API key</mark>. Once you have subscribed for api access, your product dashboard in our accounts portal (https://accounts.passiolife.com) will contain your license key, as well as your account ID.

The <mark style="color:red;">customer ID</mark> is provided here for convenience, though it is also returned with your token when requesting access. You can choose to hardcode it somewhere in your app, or just pull it out from the token response.
