# Integrate with the Perflo API

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

The Perflo application programming interface (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

These guides explain the released integration surfaces and their security requirements:

* The generated API reference, including request schemas, response schemas, authentication requirements, and errors
* [OAuth and OpenID Connect client profiles](/oauth/client-profiles)
* [Demonstrating Proof of Possession requests](/oauth/dpop)
* [Client registration requirements](/oauth/client-registration)
* [Browser access and cross-origin request rules](/oauth/browser-access)
* [Consent and connected-client controls](/oauth/account-access)
* [Protected request requirements](/guides/protected-requests)
* [Problem Details and retry rules](/guides/errors)
* [Durable operation states](/guides/operations)
* [Permanent idempotency behavior](/guides/idempotency)
* 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.
