API Modernization & Developer Portal
Challenges
Legacy SOAP-Based Services
Core payment capabilities were exposed via SOAP web services, making integration difficult for customers using modern application frameworks.
Manual Customer Onboarding
Customer onboarding and API access management relied heavily on human intervention, slowing down adoption and increasing operational costs.
Limited API Adoption Experience
Lack of a centralized developer portal restricted discoverability, documentation, and ease of API consumption.
Monetization & Governance Gaps
Business teams lacked visibility into API usage patterns, making it difficult to experiment with usage-based pricing and enforce consistent governance policies.
