Backend API Automation for OCP Platform

The core problem for the OCP Platform was a reliance on fragmented, manual API validation that could no longer keep pace with the complexity of modern digital commerce. While the platform served as the critical backbone for customer onboarding and financial transactions, its testing was restricted to isolated, manual checks using Postman. This approach failed to account for "chained" service dependencies, where multiple APIs must exchange data perfectly in a specific sequence to complete a single user journey, such as identity verification or a mobile plan purchase.

The OCP Platform serves as the vital engine powering critical backend services for customer onboarding, identity validation, sales transactions, and complex commerce workflows. These APIs are the foundational building blocks for both mobile and web application experiences. Given the high stakes of these operations, system reliability and absolute API integrity were essential to ensuring seamless customer journeys.

Client Overview

Challenges

Initially, backend services were validated through manual testing using Postman. While effective for isolated checks, this approach limited scalability and consistency. The complexity of API chains—which represent real-world customer flows—required a more robust, automated validation strategy.

Key Challenges Included:

Time-consuming manual API verification.
Lack of comprehensive end-to-end backend coverage.
Difficulty in testing complex, multi-step transactions.
Limited confidence during regression cycles.
Elevated risk of production failures due to manual oversight.

The objective was to transition the client to an automated, reliable backend testing framework that could keep pace with rapid development.

Our Solution

Certify Technologies engineered and implemented a custom Java-based API automation framework. This solution was specifically designed to validate service reliability, ensure data integrity, and handle the intricacies of chained API workflows.

Our Approach:

Automation Migration: Successfully migrated legacy manual tests into high-performance automated suites.
Schema Validation: Built automated JSON schema validations to ensure data structure consistency.
Rigorous Assertions: Implemented comprehensive HTTP status and response body assertions.
Chained Workflows: Created sophisticated API flows that simulate real-world, multi-step customer journeys.
Performance: Enabled repeatable, high-speed execution to support continuous integration.

Scope of Coverage

Our automation framework provides deep-tier validation across three primary logic layers:

1. Identity & Security

Automated National Address retrieval.
Integration validation for Yaqeen (Identity Verification).
End-to-end OTP (One-Time Password) creation and verification cycles.

2. Sales Logic

Real-time eligibility checks for customer profiles.
Intelligent MSISDN filtering and number selection logic.
Validation for Prepaid and Postpaid service transitions.

3. Commerce Logic

Dynamic SIM cost calculation engines.
Location-based delivery feasibility and logistics checks.
Payment method eligibility and transaction routing.

Conclusion

By transforming backend testing from manual checks to scalable, automated validation, Certify Technologies ensured that the OCP Platform remains stable, secure, and high-performing. This transition supports a more agile development lifecycle and guarantees a reliable foundation for all digital customer interactions.
