EchoAPI for Cursor Getting Started Guide: How to Design an API

API design is the foundation that allows developers to efficiently integrate different software systems. A well-designed API enhances the reusability and extensibility of functions, while also improving maintenance ease. Strong design facilitates smooth communication among team members, contributing to the overall success of development projects.

What is EchoAPI for Cursor?

EchoAPI for Cursor is a lightweight REST API client extension specifically designed for Cursor. This tool emphasizes simplicity, clean design, and local storage, and it is available for free. It is ideal for developers looking to quickly design and debug APIs.

Design Components of EchoAPI for Cursor

The design of EchoAPI for Cursor focuses on three main components in API design: General, Request, and Response.

General: This section describes the basic information about the API. Clearly articulating the API's purpose and functionality is crucial for helping other developers understand it.
Request: In this section, you configure the data that the client will send to the server. This includes details such as the HTTP method, URL, headers, and body.
Response: This part involves designing the expected responses from the server to the client. It specifies the anticipated status codes and formats for the response body, ensuring that users receive the correct data.

Design Overview

Practical Example: Designing a Login Interface

1. Creating the API

Navigate to the Design Module to Create the API: Set up the URL for the new API. For this example, we'll configure the endpoint as /login.

3. Setting Request Parameters

Request Parameters:
- Method: POST
- Header: Content-Type: multipart/form-data
- Body:
```
{
  "keyboardId": "12345",
  "quantity": "1"
}
```

Request Parameter

4. Specifying Expected Responses

Expected Response:

Status Code: 200 OK

Response Body:

{
  "orderId": "order4",
  "status": "Order Placed",
  "totalAmount": 99.99
}

Expected Response

Example of an Error Message:

{
  "error": "Invalid username or password"
}

Error Response

5. Saving and Pushing for Debugging

Save and Push: After completing the design, save it and push it to debug mode. This will initiate testing for the designed API.
