API Based Banking

Application Programming Interface (API) through Sunwest Bank’s BAAS platform has never been easier to integrate with. Through years of development, Sunwest has built robust and functional APIs for Fintechs and Non-Banks (such as retail brands) alike.

Sunwest Bank provides standard APIs which are modular and flexible, this makes them future-proof and enables agile development based on client demand, requirements, and regulations. Further, Sunwest offers a number of its proprietary deposit and loan software platforms that can be white-labeled to accelerate your development speed.

Sunwest APIs also include integrations with some of the largest technology companies in the world including, Plaid, ID Analyzer, Equifax, Paynet and more. Sunwest Bank’s APIs form the foundation of its BAAS (Banking as a Service) white label cloud banking solution for FinTechs.

A Few of Our Core Bank APIs Include:

Bank Account Reconciliation, Month End Closing, NSF Fees and Overdrafts, Fund Transfers, Funding an Account, Managing Bill Payments, OFAC / KYC, Credit Card Transactions, Open and Manage an Account


Sunwest Bank’s BAAS technology and software solutions enables Fintechs and other brands to quickly deploy financial products without having to internally develop solutions and select middleware partners. Sunwest can also be an advisor in developing your compliance and risk tools, and deep cross border experience for international fintechs.

Fast and easy integration through APIs allows Fintechs to concentrate on their core business and not to spend time on struggling with bank’s technology or expensive middleware solutions. Further, the lowest cost of goods comes directly from banks because middleware solutions mark-up transaction costs, which means direct Fintechs can offer lower product costs to their customers and enhance their competitive position.

Sunwest platform is a complete system that wraps seamlessly around the bank’s existing infrastructure offering faster integration, seamless monitoring, bank compliance expertise, and a lower all-in product cost.

We look forward to helping you deliver an exceptional customer experience.
