Integrating with Backend APIs

This guide provides a standardized approach for integrating with backend APIs, covering request methods, data structures, and error-handling best practices. Follow these steps to ensure seamless API interactions

1. General API Structure

All API requests should adhere to the following structure:

Request Details

• Request Type: Use POST as specified by the endpoint.
• Request URL: Include the full endpoint URL (e.g., https://api.example.com/resource).
• Request Body: Submit data in JSON format.

Example Request Body:

{
  "OrderID": 123456  // Replace with a valid identifier
}

Response Structure

The API returns responses in the following JSON format:

{
  "Success": true/false,
  "Data": {},     // Included when Success = true
  "Msg": "..."    // Included when Success = false
}

Handling Responses

• Success Handling:
  • If Success is true, extract data from the Data object.
  • Process the payload according to your application’s requirements.
• Error Handling:
  • If Success is false, display the Msg to the user or log it for debugging.
  • Implement fallback logic (e.g., retries, alerts) based on the error message.

2. Example Integration: Product Details API

To retrieve product data, use the Product Details API as follows:

API Endpoint

POST <https://usapi.hottask.com/autodev/products>

Request Structure

Include a valid ProductID in the JSON body:

{
  "ProductID": 123456  // Replace with the target product’s ID
}

Response Example

A successful response returns product details in the Data field:

{
  "Success": true,
  "Data": {
    "ID": 123456,
    "Name": "Sample Product",
    "Price": 29.99,
    "ImageUrls": [
      "<https://example.com/image1.jpg>",
      "<https://example.com/image2.jpg>"
    ]
  },
  "Msg": ""
}

Handling for Product Details API

• Success: Parse the details in Data to display product information.
• Error: If Success is false, notify users with the Msg (e.g., "Product not found").

3. Best Practices

Prompt for Calling Product Details API:

//Sample Prompt

The data for the **Product Details** needs to be retrieved through the following API. 

The API is defined as follows:
        API Endpoint:
                POST https://usapi.hottask.com/autodev/products     
        Request Structure: 
        json
            {

             "ProductID": 123456 // Sample Product ID Value

            }

        Response Example:
        json
                {
                 "Success": true,
                 "Data": {
                    "ID": 123456,
                     "Name": "Sample Product",
                     "Price": 29.99,
                      "ImageUrls": [
                         "https://example.com/image1.jpg",
                         "https://example.com/image2.jpg"
                     ]
                  },
                  "Msg": ""

                }
            Success Handling:
                If Success = true, extract data from the Data object.
            Error Handling:
                If Success = false, display the Msg to the user or log it for debugging.
