Building a Custom Developer Portal
for a Leading Finance Client Using Apigee
Client Overview
Our client is a leading cross-border payment company, authorized and regulated by the UK’s Financial Conduct Authority (FCA). With their global network of 50+ countries, technology experts, and partners, they have transformed the cross-border payment services. Unlike traditional cross-border payments, they use direct access to the local banks where customers’ payments need to be sent, thus removing the complexities, hidden fees, and lack of visibility experienced in today’s traditional cross-border payments.
Business Objective
A financial services leader wanted a more reliable developer portal solution to enhance their API developer experience. They were looking for a more robust, flexible, and secure Developer Portal that could serve a diverse set of users while meeting strict regulatory and operational requirements. We collaborated closely with the finance leader’s internal team to develop a custom portal that streamlined API access and significantly improved company onboarding and collaboration.
Why a Custom Developer Portal Matters?
A custom developer portal provides financial institutions with the flexibility, control, and security that off-the-shelf solutions often lack. In highly regulated environments, organizations require more than just API exposure, they need structured governance, granular access control, and complete visibility into developer activity.
With a tailored portal, businesses can deliver a branded, intuitive experience that simplifies API discovery, onboarding, and self-service application management. Developers can register, generate API keys, access documentation, and test APIs independently, reducing dependency on internal support teams and accelerating integration timelines.

Custom Developer Portal
Challenges
Limited Portal Customization
The default portal offered minimal flexibility in layout, branding, and user role configuration, limiting adaptability in a regulated environment.
Poor API Discoverability
Despite well-built APIs, external partners and internal users faced challenges in discovering, accessing, and onboarding to APIs independently.
Complex Access Control
The client required fine-grained, role-based access control to manage developers, partners, and business teams with distinct permission levels.
Restricted Security
Dependence on automated TLS/SSL hosting and limited support for rule-based events, analytics, and logs constrained security governance.
