So far, we’ve learned about all the aspects of designing an intuitive API that’s easy to use and implement. We’ve explored designing APIs for various foundational and advanced design problems and looked at the best practices for designing robust and scalable APIs. These APIs can meet the needs of a wide range of users according to defined functional requirements. Moving forward, let’s take a look at what next steps we can take after gaining expertise in API designs. The following sections discuss the sequence of the steps to take after the API design is ready, starting with the implementation of the API design.


The two approaches that are used for the implementation of APIs are given below:

  • Design-first approach

  • Code-first approach

The following illustration explains the difference between the two approaches:
