# Integrate with the Perflo API

> Build against Perflo's public financial API and its exact OpenAPI contract.

The Perflo API gives approved applications one domain-focused interface for supported financial capabilities. Integrations use Perflo-issued credentials and never handle upstream provider credentials.

This site is the public source of truth for integrating with the API. It documents only behavior present in the current contract.

## What this documentation covers

* The generated API reference, including request schemas, response schemas, authentication requirements, and errors
* Integration guides for authorization, proof-of-possession requests, browser origins, and client registration as those capabilities ship
* The idempotency and operation model before financial mutations become available
* Domain guides and runnable examples for each released capability

Use the **API Reference** tab for the exact endpoints available now. A capability that is absent from the reference is not part of the public API.
