Now, almost every website needs APIs for better user experiences and services. Sometimes, building an API is a very repetitive task. API development contains API endpoint design, creating an API, giving the right response, etc.

ChatGPT can assist you in API development with all these tasks. Here are a few prompts and examples that will help you with API development.

API endpoint design

API endpoint design is crucial. If you do it wrong, it can lead to poor performance, an increase in maintenance costs, reduced usability, and a frustrating developer experience.

Here is the prompt that will help you with API endpoint design.

Prompt:

Design API endpoints for me with code. It should be reusable, easily maintainable, understandable, handle all errors, give proper responses, and be scalable.

Technology Stack: [enter your technology stack here]

Functionality: [explain your functionality

Example: Design API endpoints for me with code. It should be reusable, easily maintainable, understandable, handle all errors, give proper responses, and be scalable.

Technology Stack: Node.js, Express.js, MongoDB

Functionality: commerce cart system

(This prompt output might be long, if ChatGPT gives an incomplete response the write prompt: “Complete the response”)

Writing a code for complex APIs

This prompt will help you write a complex and customised API as per your requirements.

Prompt:

Write an API that gives a proper response with a message, logs errors, and validates the user's required data.

Functionality: [explain the requirement in details with input and desired output]

Technologies: [enter your technology stack here]

Example:

Write an API that gives a proper response with a message, logs errors, and validates the user's required data. Functionality: The user will pass the period to get the sales amount. Currency can be in INR, USD, or GBP. But return the result in INR only. The period can be a date range, month range, or year range. Identify the pattern and write code accordingly.

Technologies: Node.js, Express.js, Mongoose, Redis cache

API Authentication

APIs can be called by any platform or tool. We need to secure the API and give access to authenticated users. To do this, you will have to write middleware. Writing middleware is a complex task, but ChatGPT can help you do it in a few minutes.

Prompt:

Write a middleware to authenticate using [explain how you want to authenticate (session, JWT), authenticate (session), and what you want after authenticating the user].

Technologies: [enter your technology stack]

Example 1: Write a middleware to authenticate using JWT and store the access data in a database. Technologies: Express.js and Mongoose

Example 2: Write a middleware to authenticate using JWT and store the access data in the database. Technologies: Spring boot, MySQL, Hibernate
