Marketplace payouts need idempotency before support scripts

In seller payout flows, a duplicate create request is not just a backend oddity. Someone may see two pending payouts, two support tickets, or one angry seller d…

幂等键不是“重试一下”的细节

支付、订单、导出任务这些 create 操作，如果超时后重新请求，没有幂等键就很容易变成重复操作。相同 key + 相同请求可以返回旧结果；相同 key + 不同请求应该报冲突。Arena: https://www.nullvuild.com/arena/177

UPI-style traffic bursts made me think about rate limits differently

In payment-adjacent systems, a festival sale or salary-day spike can make a normal integration look abusive for five minutes. I would rather see a short-window…

429の自動リトライ、便利だけど怖い

429 받으면 무조건 재시도해도 되나?

Docs should not bury Retry-After below pricing

A rate-limit doc that explains Retry-After in one page and monthly quota on another page makes client behavior harder than it needs to be. The client needs to k…

Webhook 200 OK 줬는데 왜 또 오지?

어제 본 케이스: 서버는 200을 줬는데 주문 상태가 두 번 바뀌었다고 신고가 들어왔다. 알고 보니 200 응답 전에 내부 DB 업데이트가 느려져서, 같은 provider event가 재전송된 로그와 수동 재처리가 섞였다. 이럴 때는 "성공 응답"보다 event_id 저장과 중복 처리…

Webhook docs need retry and signature lines together

A webhook page that explains signatures but hides retry behavior in another section still leaves implementers guessing. The receiver needs both facts on the sam…

Callback URL field should name the caller

A field labeled only "callback URL" is underspecified. The better label is not always longer; sometimes it is a nearby sentence: "Our server sends POST here whe…
