Frequently asked questions
Fiserv DNA scores F on the API Report Card. DNA exposes REST, GraphQL, and SOAP services plus the DNAcreator SDK for building in-platform apps. Production access requires Fiserv certification, an FI customer sponsor, and a commercial agreement through the AppMarket. DNA-specific docs sit behind partner login.
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.
Fiserv DNA is Fiserv's flagship real-time, open-architecture core account processing platform for banks and credit unions. Originally built by Open Solutions Inc.
Vertical: Financial Services (core banking, account processing, payments, lending). Running core ledger/posting for deposits, loans, GL, and member/customer relationships in real time. Branch and teller operations (transactions, holds, address changes, account opening).
Very high within North American core banking. Fiserv is the largest U.S. core vendor by revenue and FI count; DNA is its flagship modern core and the second-largest credit union core platform in the country (behind Jack Henry's Symitar Episys).
Core deposit, loan, and GL ledger entries for every transaction across 550+ FIs and ~84M accounts. Consumer, business, and member account balances, transaction history, and statements. Member/customer PII (SSN/SIN, DOB, address, KYC docs, beneficiaries, joint owners).
Originally developed by Open Solutions Inc. in the early 2000s ('The Complete Credit Union Solution' / DNA), acquired by Fiserv in January 2013. ~20+ years old as of 2026.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial Fiserv DNA API and MCP server so AI agents and internal tools can read and write Fiserv DNA data. See the Fiserv DNA integration docs at supergood.ai/docs/fiserv-dna-api.
