Fixes an agent's Stripe meter double-counting usage from missing idempotency on usage records. Covers deterministic idempotency keys, crediting inflated invoices, and monitoring. Not for under-counted usage or fixed-price billing errors.
Fixes duplicate Adyen charges from retries that used a new idempotency key each time. Use when customers were charged twice because the agent regenerated the key per attempt. Not for duplicate orders or for deliberate separate charges.
For sales-outreach (SDR) agents: Webhooks fire twice and sometimes not at all, so the receiver must be idempotent and the sender must be verified. Dedupe on the event id, return 200 only after the work is durably recorded, and reconcile with a periodic poll so missed events cannot stall the pipeline.

A guide to preventing duplicate public replies from support agents, in the business-apis-integrations category: send dedupe, idempotency keys, and double-submit guards. Use when customers receive the same reply twice, or when building reply-sending guardrails. Not for reply content, ticket merge, or notification desig…
Teaches an agent to register webhooks idempotently and guard campaign triggers against duplicate delivery. Covers list-before-register, URL plus event dedupe, idempotency keys on triggers, and processed-event logs. Use when a campaign fires twice because a webhook was registered twice. Not for campaign content or audi…
A guide to making webhook consumers idempotent against double-processed ticket events, in the business-apis-integrations category: event-id dedupe, idempotency keys, and safe retry design. Use when ticket webhooks apply twice, or when building webhook consumers. Not for webhook endpoint setup, signature verification, …

Fixes multi-tenant onboarding where webhook events get routed to the wrong tenant's workspace. Use when one customer's webhook updates another customer's onboarding state. Not for single-tenant webhook failures or signature mismatches.
Adds event ordering to webhook handlers: ignore stale events. Use when state regresses after webhooks. Not for duplicate deliveries.
Handles out-of-order chargeback webhook events: timestamp-based state updates that ignore stale events, plus idempotent transitions and periodic reconciliation. Use when event sequences contradict each other or states flip backwards. Not for duplicate deliveries or missing events.

Hardens a dispute webhook handler that crashes on evidence_required events: null-safe parsing, async processing after acknowledgement, and a dead-letter queue for poison payloads. Use when one event type kills the handler while others pass. Not for signature failures or missing events.

Reconciles PayPal IPN and webhook chargeback events that disagree: declaring webhooks the system of record, mapping IPN statuses to webhook types, and correlating by transaction id. Use when both feeds are active and the ledger shows conflicting states. Not for single-feed delivery failures.
Vectle found the following relevant skills: - Stripe webhook signature mismatch on AWS Lambda: use raw event.body and the whsec_ secret - paypal webhook PAYMENT.SALE.COMPLETED never arrives for a billing agreement

Handles duplicate dispute webhook deliveries: idempotent processing keyed on event id, fast acknowledgement, and checking for doubly-registered endpoints. Use when the same event arrives twice and the ledger shows double entries. Not for events that never arrive or arrive out of order.
Explains the closed-dispute evidence wall on Stripe: confirming status and deadline, submitting while still open, and building due-date alerts so it does not recur. Use when an evidence upload errors on a closed dispute. Not for duplicate-evidence rejections on an open dispute.
Handles rejected duplicate dispute evidence on Stripe: reading the existing evidence object before submitting, updating only on real changes, and deduplicating by dispute id. Use when the API rejects an evidence POST as a duplicate. Not for evidence rejected on content, or closed-dispute deadline problems.
