Learn to implement exponential backoff in Python to handle rate-limited APIs and avoid HTTP 429 responses, ensuring reliable and efficient API interactions

intermediate Published 22 May 2026
Action Steps
  1. Import the required libraries, including time and random, to handle backoff logic
  2. Define a function to handle HTTP 429 responses and initiate backoff
  3. Implement exponential backoff using a loop that increases the wait time after each failed request
  4. Use a random jitter to prevent the thundering herd problem
  5. Configure the maximum number of retries and backoff factor to suit the API requirements
