REST API Development Process We Follow

As one of the leading REST API development services company, Flatworld has curated a highly efficient work methodology that involves studying your systems, developing a strategy, designing the APIs, and accommodating all the solutions you need in one streamlined process. Here's how we make it all possible -


01. Systems and API Evaluation

Before we can draft a strategy, we examine your existing API and systems to determine whether REST can be built upon or your systems will require brand new API development


02. Configuration and Specifications Planning

Then, keeping the scalability in mind, we start defining the configurations and specifications of the REST API according to your unique business needs


03. REST API Design and Development

This is the main step where the architectural frameworks of the APIs are designed and codes are written. In this step, we model different versions of the API to finalize one configuration


04. Testing

Once finalized, the REST API goes through multiple phases of testing to ensure there is no error, bug, or security loophole whatsoever


05. Deployment

Finally, we authenticate and authorize the REST APIs and deploy them to your server. We also offer integration support with third-party applications, whenever needed
