Rest API - HTTP Status Codes

You are designing an API client that must handle 429 Too Many Requests responses gracefully. Which approach best prevents overwhelming the server while retrying?

ARetry immediately without delay to speed up requests

BUse exponential backoff with jitter based on Retry-After header

CIgnore 429 errors and continue sending requests

DStop all requests permanently after first 429

Step-by-Step Solution

Solution:

Step 1: Understand exponential backoff with jitter
This method increases wait time exponentially and adds randomness to avoid bursts.
Step 2: Compare with other options
Immediate retry or ignoring 429 overloads server; stopping permanently is too strict.
Final Answer:
Use exponential backoff with jitter based on Retry-After header -> Option B
Quick Check:
Exponential backoff + jitter = best retry strategy after 429 [OK]

Quick Trick: Exponential backoff with jitter prevents server overload [OK]

Common Mistakes:

Retrying immediately ignoring server limits
Ignoring 429 errors completely
Stopping requests forever after one 429
