Bank-branded portal and APIs give commercial clients a governed path from first visit to production.

Prolific Banking today announced the rollout of the FI-Streams Developer Portal and APIs, a bank-branded developer portal within Prolific Open Digital that lets banks offer self-service APIs to their commercial clients.

AI is turning corporate finance and IT teams into software builders. They can now extend NetSuite, Dynamics, Sage Intacct, SAP, and homegrown ERPs in weeks rather than quarters, and they expect their bank to plug in.

"A client who once accepted 'it's on the roadmap' will now build the capability themselves and look for a bank that can plug in," said Taylor Ousley, VP of Sales and Marketing at Prolific Banking. "The Developer Portal lets our bank partners say yes, on their brand and under their controls."

Each client developer receives a separate identity with scoped entitlements per account, operation, and environment. Building is not moving money: only an entitled user or approved policy can release a live payment.

The portal guides client developers through one governed path: discover, register, build, certify, go live, and operate, with bank approval, sandbox testing, and API certification before live credentials are issued.

The bank stays in control: entitlements, dual approval, limits, and audit trail apply whether a request arrives by portal, file, or API. Banks can launch in under four months, compared with an estimated 12 to 18 months to build in-house.

The Developer Portal and APIs are one product within FI-Streams, covering payments, reporting, stop payments, positive pay, and webhooks. Banks interested in launching a developer program can request a demo at prolificbanking.com or contact sales@prolificbanking.com.
