Inbound SMS webhook: retry, ayos ng event, at idempotency sa pagtanggap

Gabay B2B sa receive path: paano nagre-retry ang inbound SMS webhook, bakit hindi garantisado ang ayos, at paano pinoprotektahan ng idempotent handler ang prepaid ops at support macro.

Kinukuha ng outbound SMS ang mga dashboard. Ang inbound ang lugar kung saan talagang bumabagsak ang STOP, HELP, at sagot ng customer — at kung saan ang mga walang-muwang na handler ay gumagawa ng dobleng ticket, dobleng epekto sa wallet, at compliance ghost na “hindi namin natanggap ang STOP”. Kung ang receive path ay nag-aakala ng exactly-once nang may ayos, madudurog kayo sa unang totoong outage.

Ipinapakete ng IOSOR ang inbound messaging sa parehong white-label prepaid surface gaya ng outbound: ma­verify na event, brand-safe payload, nang hindi tumitira sa dayuhang ops portal para magkasundo ng bagyo ng sagot.

Bakit nagre-retry ang mga webhook

Sa karamihan ng platform, nangangako ang inbound webhook ng at-least-once na may retry, hindi mahiwagang exactly-once na mahigpit na ayos.

  • Dobleng POST ng parehong logical event
  • Huling dating pagkatapos ng timeout
  • Minsan out-of-order laban sa ibang uri ng event

Maaari pa ring maramdaman ang maayos na UX kung ang store ninyo ay gumagamit ng deterministic merge — hindi kung umaasa kayong hindi kailanman magle-glitch ang wire.

Ang tatlong failure mode na dapat mong idisenyo

Failure mode What happens What breaks if you ignore it
Duplicate delivery Same event ID arrives 2+ times Double-counted replies, doubled STOP, duplicate threads
Out-of-order events A later-timestamped event arrives first A delivered status regresses to sent
Partial/ambiguous failure You processed but the ack was lost The platform retries work you already did

Idempotency: ang property na nag-aayos sa lahat ng tatlo

Hindi libre ang inbound sa pera at ops side effect:

  • Maaaring mag-debit ang auto-reply sa prepaid wallet
  • Dapat pigilan ng STOP handling ang hinaharap na marketing send
  • Hindi dapat magbukas ng tatlong ticket ang support macro para sa tatlong POST

Checklist para sa idempotent receive handler:

  1. Persist ang inbound event id bago ang side effect
  2. I-short-circuit ang duplicate gamit ang dating outcome
  3. Bigyan ang auto-reply send ng sariling idempotency key
  4. I-log ang correlation: inbound id → wallet line → reply id

Pagkakasunod-sunod ng event: bakit mapanganib ang “last write wins”

Webhook events for the same message are not guaranteed to arrive in occurrence order. A retry of an earlier queued event can land after a later delivered event. If your handler overwrites status with whatever just arrived, a stale late event can silently regress a delivered message. Compare timestamps (or a monotonic sequence) before writing.

Compliance-critical inbound keywords deserve the strictest idempotency. A duplicated STOP must never double-log an opt-out or send two confirmations. A duplicated HELP must never fire two help messages to the same number in the same minute. Route keyword processing through the same dedupe table as regular inbound messages.

Mga red flag

At partnership scale the receive ledger is finance and compliance evidence: durable event ids, duplicate short-circuits, and wallet-line correlation. Demand the same white-label hygiene as outbound. Near USD 1,000+ monthly usage, inbound discipline is commercial discipline — prove single-truth STOP handling before expanding production corridors.
