How APIs Use Rate Limit Headers to Prevent Thundering Herd Problems

Episode 47 of The API Podcast dives into the 'thundering herd' problem — when thousands of clients retry simultaneously after a rate limit reset, crushing your API. Lucas and Luna explore how Stripe and GitHub use headers like Retry-After and X-RateLimit-Reset to stagger retries, why exponential backoff isn't enough, and how API gateways can deduplicate incoming requests to keep services stable. They walk through a real-world case from Twilio's 2023 incident postmortem and discuss how fair-use rate limiting with jitter saved a fintech startup from cascading failures. By the end, you'll know exactly what headers to look for and how to build clients that don't panic on a 429 status code. #ThunderingHerdProblem #RateLimiting #RetryHeaders #StripeAPI #GitHubAPI #Twilio #ExponentialBackoff #Jitter #APIResilience #ClientBackoff #HTTP429 #RetryAfter #XRateLimitReset #APIDesign #Microservices #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
