Case Study: Transforming Fraud Management with Custom API Integration for Accourt
Pulsion had the privilege of leading a transformative API integration project for one of the UK’s largest financial institutions, Accourt. The client faced significant challenges with an outdated Fraud Management system built on SharePoint, plagued by scalability issues, a flawed user interface, and ineffective reporting capabilities.
Recognising these hurdles, our team developed a fully tailored API-driven solution, leveraging a serverless architecture hosted on Amazon Web Services (AWS). This custom-built system enabled seamless data integration, enhanced reporting accuracy, and eliminated the inefficiencies of the previous infrastructure.
The new solution provided Accourt with a scalable, cost-effective system designed for high performance and reliability. The serverless design ensured improved resilience across multiple availability zones, reducing maintenance requirements while supporting over 200,000 transactions and 2,000 users monthly.
Vaughan Collie, Accourt’s Managing Partner, praised the solution’s seamless performance and enduring benefits, emphasizing Pulsion’s dedication to crafting custom API integrations that align perfectly with clients’ goals and deliver measurable success.

Developers often use JavaScript with Node.js to develop client-side APIs while using Python with Flask or Django for fast development on either side. The developer may also use Ruby to build RestFUL APIs or PHP with Laravel or Symfony for more bespoke solutions.
Factors that influence the timeline for developing or integrating API solutions depend on project complexity, the number of endpoints, third-party API integration, project scope, intended features, and the implementation of secure API communications. API integration for secure communications can take a few weeks to months to ensure seamless integrations and secure data exchanges.
