SoFi Partner Offer Pre-Qualification API is one of 4 APIs that [SoFi](https://apis.io/providers/sofi/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Lending, Personal Loans, Student Loan Refinancing, Prequalification, and Partner API. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

SoFi's partner-offer-api (documented as Partner Offer Pre Qual V2) is a real, first-party external REST API that exposes SoFi's underwriting model to approved partners, returning real-time Personal Loan (PL) and Student Loan Refinancing (SLR) offers based on user-entered criteria via a single POST /po/api/v2/loan-offer/json endpoint. User-entered criteria can be saved to pre-populate a SoFi loan application when an offer is selected on the partner's site, and a 2021 release added specialty SLR handling for Medical and Dental graduate programs. Authentication is by API key / UUID (one per product type, PL or SLR) passed as the accountId in the JSON body, over HTTPS only; testing uses base URL https://dev-external-0.sofitest.com and production uses https://www.sofi.com. Endpoint, method, base URLs, auth model, and response codes were harvested faithfully from SoFi's public Postman workspace (team-sofi / sofi-api).
