ERP Integration

Connect your SAP S/4HANA or Oracle systems to the V-Ledger ecosystem using our Asset Twin Sync API.

The Asset-Twin-Sync Workflow

Integrating a Digital Product Passport into a high-volume manufacturing line requires a decoupled approach. The ERP system reserves the "Digital Twin" first, and the physical "Hardware Anchor" (NFC chip) is bound to it later on the assembly line.

Step 1: Provisioning (ERP)

POST /v1/erp/provision

When a production order is created in SAP, the system calls the provisioning endpoint. This creates a placeholder Asset Twin on the V-Ledger platform without requiring a physical chip yet.

{
  "sap_metadata": {
    "material_number": "MAT-GTIN-8912",
    "order_id": "CHARGE-2026-X1"
  }
}

Response: Returns a vledger_internal_id which the ERP saves in its database.

Step 2: Hardware Binding

POST /v1/factory/bind

On the factory floor, the physical NTAG 424 DNA chip is attached to the product. A scanner reads the chip's UID and cryptographic signature, and binds it to the previously provisioned Asset Twin.

{
  "vledger_internal_id": "vledger_prov_abc123",
  "hardware": {
    "chip_uid": "04A1B2C3D4E5F6"
  }
}

At this moment, the Asset Twin is locked to the physical item. The product is now 100% forgery-proof.

Bulk Operations

For manufacturing lines producing thousands of items per hour, use the /v1/erp/provision/bulk endpoint to pre-allocate batches of internal IDs to minimize HTTP overhead.
