Use your account's API key to authenticate requests with Reflect.
To access the Reflect API, you must sign all requests using your API key. API keys are associated with your account, not your user, which means that all users of your account will share the same API key.
For every API request, an X-API-KEY
request header must be populated with your API key.
To view your API key, navigate to Settings > Account Information, and scroll to the “API Access” section.
