Authentication Metrifox uses API key-based authentication to identify and authorize requests made by tenants. Each tenant is issued one or more API keys. One of these keys must be included in the request headers to access protected endpoints.
Base URLs: core and checkout endpoints use https://api.metrifox.com, while usage endpoints use https://api-meter.metrifox.com.

​
🔑 Your API Key

You can generate and manage your API keys from the Metrifox dashboard under: Developers > API Keys

​
🧾 Making Authenticated Requests

Include your API key in the x-api-key header for all requests:

​
