In this tutorial, we will explore how to handle responses in API integration. API responses are crucial for understanding the success or failure of an API call and for processing the data returned by the API.

Key Concepts

  • HTTP Status Codes: These are three-digit numbers returned by the server to indicate the status of the request. Common status codes include 200 (OK), 404 (Not Found), 500 (Internal Server Error), etc.
  • Response Data: The actual data returned by the API, which can be in various formats like JSON, XML, etc.
  • Error Handling: Properly handling errors to ensure that your application can gracefully handle unexpected situations.

Steps to Handle Responses

  1. Check HTTP Status Code: First, check the HTTP status code of the response to determine if the request was successful or not.
  2. Parse Response Data: If the status code indicates success, parse the response data to extract the necessary information.
  3. Error Handling: If the status code indicates an error, handle it appropriately, such as displaying an error message to the user or logging the error for further investigation.

Example

Here's an example of how to handle a JSON response using Python:

import requests

response = requests.get('/api/data')

if response.status_code == 200:
    data = response.json()
    # Process the data
else:
    # Handle error
