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
• Demonstrating Proof of Possession requests
• Client registration requirements
• Browser access and cross-origin request rules
• Consent and connected-client controls
• 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.
