As commercial banking customers increasingly rely on external accounting, treasury and financial management platforms, banks are under pressure to provide secure, real-time access to financial data without compromising control or security. The latest deployment by Webster Bank highlights how financial institutions are investing in open banking infrastructure tailored specifically for business and commercial clients, rather than focusing solely on consumer use cases.
Webster Bank Goes Live on FI-Streams Connector
US-based Webster Bank has implemented Prolific Banking’s FI-Streams Connector, enabling commercial customers to securely connect their accounts to a broad ecosystem of third-party financial applications through Plaid’s Core Exchange platform.
The integration provides business clients with access to account information, transaction histories and authentication capabilities while allowing seamless connectivity with accounting software, treasury management solutions and financial management platforms available across the Plaid network.
Built using Plaid’s Financial Data Exchange (FDX)-aligned API framework, the solution gives Webster Bank customers access to thousands of connected applications while maintaining secure data sharing and permission controls.
Purpose-Built for Commercial Banking
Unlike many open banking initiatives that focus primarily on retail customers, the FI-Streams implementation was designed specifically around the needs of Webster Bank’s commercial and business banking customer base.
The platform integrates directly with Webster Bank’s digital banking environment, synchronising account entitlements, user permissions and authentication processes. This allows businesses to connect external applications without requiring separate onboarding or manual authorisation workflows.
Prolific Banking customised the deployment to align with Webster Bank’s existing commercial banking infrastructure, ensuring that data connectivity, access controls and client permissions remain consistent across both internal and third-party systems.
Growing Demand for Connected Banking Experiences
The rollout reflects a broader shift across the banking industry as commercial clients increasingly expect their banking platforms to integrate seamlessly with the software they use to manage finance, accounting, cash flow and treasury operations.
As businesses adopt more cloud-based financial tools, banks are being required to provide secure API-driven access to account information while maintaining governance, security and compliance standards.
By connecting to Plaid’s ecosystem through Core Exchange, Webster Bank can offer commercial customers a more connected banking experience without requiring direct integrations with each individual application provider.
