Api overview

This documentation describes Fathom’s REST API.

Authentication

All REST API resources are authenticated with API keys generated via the Fathom website’s settings area.

Rate limiting

We use several rate limiting strategies to ensure the availability of our APIs. Rate-limited calls to our APIs return a 429 status code. Calls to our APIs include headers indicating the current rate limit status.

Global rate limits

Authenticated requests are subject to a global limit. This is the maximum number of calls that your account can make to the API per minute. Endpoints subject to rate limits may return the headers below.

Header	Description
RateLimit-Limit	The maximum number of requests allowed in a time window
RateLimit-Remaining	The number of requests remaining in the current time window
RateLimit-Reset	The time remaining in the current time window

Currently, you are able to make a maximum of 60 calls to the API in a 60 second window.
