Our API Development Process

Discovery Phase icon

Discovery Phase

We review your project specification (if any), existing concepts, and business-product idea alignment and define the solution’s value proposition, risks, and deliverables. Once we complete the analysis, our specialists will build a high-level project roadmap that perfectly correlates with your API requirements.

Length: 2-4 weeks

Conduct the Audit

API Architecture Design

We kick the API development project off by starting to design multi-layered API architecture, choosing the best-fit architectural style, embedding high security, and assessing non-functional requirements. As a result, all APIs should meet 5 fundamentals: usability, reliability, scalability, testability, and security.

Length: 1 month

API Development

API Development & Testing

We define all API responses (200, 201, 202, etc.), handle exceptions and errors, build an API endpoint, implement pagination and criteria-based search (if needed), analyze API performance, prepare in-depth documentation, add versioning, and utilize throttling. Once done, we perform API testing using isolation, real-life data simulation, multi-network conditioning, and edge cases.

Length: 3+ months

Monitoring and Further Iterations

Monitoring and Further Iterations

API design and development are halfway to success. Seamless integration, performance, and security are what brings you to the finish line. Once we’ve deployed the API, we start tracking multiple metrics like API uptime, monthly active users, requests per month, response times, server CPU/memory usage, time to first 200 OK responses, and others. Following a data-driven and feedback-based approach, we ensure stable performance and continuous improvement for your custom API.

Ascendix Technologies migrated our business from our old CRM to Microsoft Dynamics, customizing it for both our industry and our specific workflow at the time. So, instead of spending 10 hours to provide a report or service to a client, our brokers can now do it 200% faster and be as efficient and probably more effective than they would otherwise have been a year ago.
