Integrate with a warehouse management system (WMS) to receive inventory updates via ShipBob webhooks

Steps

1. Register a webhook endpoint in ShipBob by POST to https://public-api.shipbob.com/1.0/webhook with your HTTPS callback URL and the desired topic (e.g. inventory_changed)
2. Secure the endpoint by validating the X-Hub-Signature header on each inbound webhook POST using your registered webhook secret
3. Parse the inventory_changed payload to extract the inventory_id, on_hand quantity, committed quantity, and fulfillable quantity fields
4. Map ShipBob inventory_id values to your internal SKU identifiers using a lookup table built from GET https://public-api.shipbob.com/1.0/inventory
5. Update your internal inventory ledger and trigger reorder alerts when fulfillable quantity drops below your reorder point threshold
6. Respond with HTTP 200 within the expected timeout; queue slow processing work asynchronously to avoid webhook retry storms
