SimpleNexus API
SimpleNexus runs two public documented REST surfaces at developer.ncinomortgage.com: the new nCino Mortgage API v1 with OAuth 2.0, semantic versioning, and retrying webhooks, plus legacy SNAPI covering loans and documents. Docs and Postman are open; tokens are issued, not instant self-serve.
Frequently asked questions
SimpleNexus scores D+ on Supergood's API Report Card. SimpleNexus runs two public documented REST surfaces at developer.ncinomortgage.com: the new nCino Mortgage API v1 with OAuth 2.0, semantic versioning, and retrying webhooks, plus legacy SNAPI covering loans and documents. Docs and Postman are open; tokens are issued, not instant self-serve.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
SimpleNexus is a mobile-first digital mortgage Point-of-Sale (POS) and homeownership platform that unifies the loan officer, borrower, real estate agent, and settlement-services experience for U.S. mortgage lenders.
Vertical: Financial Services, specifically the Mortgage Point-of-Sale (POS) / Digital Mortgage subcategory that sits in front of the Loan Origination System (LOS). Mobile loan application capture (1003) with document upload from the borrower's phone. LO pipeline management and CRM on iOS/Android.
High within mortgage POS.
Loan applications (1003 data): borrower demographics, employment, income, assets, liabilities, REO, declarations, demographic information addendum. Loan events and pipeline state: application started, application submitted, conditions cleared, CTC, funded, closed.
Founded 2011; ~15 years old as of 2026. Mobile-first DNA, SimpleNexus was the first POS to lead with a native iOS/Android loan officer + borrower app rather than a desktop web portal, which is still a differentiator.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official SimpleNexus MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. SimpleNexus doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
