# Webhook Events Canonical URL: https://babadook.tech/sub-modules/webhook-events Entity: sub-modules Content hash: 692d30936b626226f725d899a007b9b25d2191e3ef4950615aaf5b1b50a0014f Stop polling for what already happened — the event arrives with proof. Integration teams burn weeks on polling schedules, missed updates, and reconciliation jobs that exist only because nobody told them what changed. Webhook Events tells them: 100+ business moments delivered with signatures, schemas, and idempotency — so consumers react to facts instead of hunting them. ## Event families in operation Each family below emits from the same commit path as the operation itself — events never describe something the ledger did not do. ### data Viz ### data View section: stages ### Order and Fulfillment Quote, order, promise, shipment, delivery, and return events with the commercial identifiers attached. Storefronts, 3PLs, and EDI partners consume the same stream instead of polling order status. ### Inventory and Warehouse Receipt, move, count, pick, pack, and shipment events with bin, lot, and serial context. Replenishment and external systems react to stock facts as they validate. ### Finance Invoice, payment, close-stage, and consolidation events with ledger references. Reporting and compliance consumers build from posted facts, never drafts. ### Workforce and CRM Roster, attendance, opportunity, case, and loyalty events with actor and policy context. Scheduling, payroll, and engagement systems stay current without batch exports. ## Delivery contract Subscriptions declare endpoint, families, filters, secret, and retry policy. Deliveries sign with HMAC over the canonical payload, track attempts with backoff, and park poison messages in dead-letter with the failure evidence attached. Idempotency keys make redelivery safe to reprocess. ### data Viz ### data View section: delivery ## Webhook guarantees - **Signed payloads:** HMAC signatures over canonical bytes with schema versions attached - **Safe redelivery:** Idempotency keys make retries and replays reprocessable without duplication - **Scoped streams:** Family and object filters so endpoints receive only their contract - **Replayable history:** Retained positions rewind missed events after outages or backfills - **section:** capabilities ## Webhooks by consumer Event consumption bends per consumer — same signed envelopes, different reaction stakes. ### data Viz ### data View section: industries ### Storefronts and 3PLs Order and shipment events drive storefront status, tracking pages, and 3PL handoffs. Retries with backoff absorb consumer outages without losing the stream. ### Finance Systems Invoice and payment events feed external reporting and compliance tools from posted facts. Schema versions let consumers migrate parsers on their schedule. ### Data Platforms Warehouse and lake ingestion replays history into new consumers for backfill, then follows live positions. Idempotency keys keep replays duplication-free. ## Webhook Events questions ### Section 1 How do we verify a webhook is genuinely from XRP? Each payload carries an HMAC signature over canonical bytes plus a schema version. Receivers recompute against the subscription secret — mismatches refuse before any processing. ### Section 2 What happens when our endpoint is down? Deliveries retry with backoff while the position retains. On recovery the stream replays missed events in order; poison messages park in dead-letter with failure evidence instead of blocking the stream. ### Section 3 Can we replay history into a new integration? Yes. Subscriptions rewind from retained positions into sandbox or production endpoints, so new consumers backfill without asking source systems to resend anything. ### Section 4 Our security team distrusts inbound webhooks. What do we tell them? Show them the signature scheme, the schema pinning, and the dead-letter evidence. Every payload is verifiable before processing — which is more than polling ever offered. ### data View section: faqs ## content section value: Integrations stop polling and start reacting: the event arrives with its evidence, the signature proves it, and the idempotency key makes redelivery safe. ## Section 7 100+ event families across orders, inventory, finance, workforce, and CRM ## Section 8 Signed payloads with schema versions and idempotency keys ## Section 9 Family and object-scope filtering per subscription ## Section 10 Delivery tracking with retry policy and dead-letter evidence ## Section 11 Replay from retained positions after outages ## Section 12 Sandbox event replay for integration testing ## Relationships ### products - XRP — https://babadook.tech/products/xrp ### modules - Data Flow — https://babadook.tech/modules/data-flow
