Leitet Shop-Webhook-Bestellungen mit Lagerprüfung an Lieferant, Versand, CRM und ERP weiter

## Process store orders from webhook to supplier, shipping, CRM and ERP with stock checks Who it is for. Online stores and trading companies that still update supplier, shipping, CRM and ERP by hand after every order. What it does - Verifies the store webhook signature on the raw body, normalises the order and de-duplicates by order id. - Checks stock with the supplier. In stock: purchase order, shipping label with tracking, customer email, CRM upsert, ERP inventory update. - Out of stock: BACKORDER tag, customer email with the lead time, alert to operations. - A scheduled branch syncs ERP inventory to the CRM every six hours and posts a low stock digest. - Retries on every API call; bad signatures dropped and alerted; duplicates acknowledged and not re-run. Setup 1. Set base and the store signing secret in Config, or swap each HTTP Request node for your store, supplier, carrier, CRM and ERP nodes. 2. Register the Webhook URL as the store's order created webhook. 3. Activate; the six hourly schedule runs the inventory sync. All external systems are reached through HTTP Request nodes against base in the Config node, so the whole flow imports and runs against any REST backend; swap any of them for the native n8n node of your system. Built and tested on sample data by Finamatik: https://finamatik.com/work/order-to-fulfilment Requirements. n8n 1.100 or later; for the AI steps, a model endpoint at base/llm/complete or the OpenAI or Anthropic node in its place; your own systems reachable over HTTPS. How to customise. Every rule lives in one Code or Config node and is named for what it decides; change the thresholds there, not in the branches.
