The Base URL for Fiskil's Data APIs is https://api.fiskil.com/v1

API protocols and headers

The Fiskil API uses POST and GET requests to communicate and HTTP response codes to indicate status and errors. All responses come in standard JSON. The Fiskil API is served over HTTPS TLS v1.2+ to ensure data privacy; HTTP and HTTPS with TLS versions below 1.2 are not supported.

Requests target a major API version selected by the X-Fiskil-Version header or your Console pin — see API Versioning.

Postman Collection

The Postman collection is a convenient tool for exploring Fiskil API endpoints without writing code. The Postman collection provides pre-formatted requests for almost all of Fiskil API endpoints. All you have to do is fill in your API keys and any arguments.
