In the video, I explained the importance of idempotent APIs in handling network glitches in payment services. By ensuring APIs are idempotent, servers process requests exactly once, avoiding unintended behaviors like duplicate transactions. I discussed the challenges of automatic retries and the solution of using item potency keys to track requests. This simple approach helps maintain exactlyonce semantics, crucial for critical APIs like payment services. I highlighted how payment services like Stripe implement idempotency and recommended checking their API documentation for further understanding.
