856 ASN
Receive and parse an EDI 856 ASN
Inbound ASN flow: webhook payload for EDI 856, normalized JSON fields, and mapping tips for WMS/ERP ingestion.
Quick answer
Can I poll instead of using webhooks?
Webhooks are recommended for near-real-time receipts. You can also inspect inbound documents in the dashboard while building your handler.
Inbound flow overview
When a partner sends an 856 ASN, SignalEDI validates structure and emits a webhook with normalized JSON for WMS/ERP ingestion.
- HL hierarchy: shipment → order → pack → item
- Ties to the original 850 PO when present
Example webhook envelope
Verify X-SignalEDI-Signature before trusting the body.
{
"event": "document.validated",
"documentId": "doc_01H…",
"partnerId": "retailmart",
"documentTypeCode": "856",
"payload": {
"shipmentId": "SHP-2201",
"cartons": [{ "sscc": "00012345678901234567", "lines": [{ "sku": "SKU-100", "quantity": 24 }] }]
}
}Mapping to your system
Map shipmentId and SSCC barcodes to warehouse receipts. Keep idempotency on documentId because webhook retries are expected on 5xx responses.
