Setting up transit delivery from a 1C-Bitrix supplier's warehouse

Configuring Transit Delivery from Supplier Warehouse 1С-Bitrix

Transit delivery is a dropshipping scheme: order arrives at site, store forwards it to supplier, supplier ships goods directly to customer. Store doesn't physically hold goods. In Bitrix this scheme requires: goods-supplier binding, mechanism for automatic order transmission, and status tracking from supplier.

Binding goods to suppliers

Create custom infoblock property SUPPLIER_ID of type "List" or "Binding to infoblock" — depends on whether suppliers are stored as infoblock elements or in separate table. If many suppliers or detailed data needed (API key, email, order format) — use separate bl_suppliers table.

Structure bl_suppliers: id, name, order_method (api/email/edi), api_url, api_key, email, order_template, active.

Goods-supplier binding: table bl_product_supplier with fields product_id, supplier_id, supplier_sku (supplier's article), price, lead_time_days.

Transmitting order to supplier

On payment (OnSaleOrderPaid) or manual status transition — determine supplier by basket goods and transmit order:

$basket = $order->getBasket();
$supplierOrders = [];

foreach ($basket as $item) {
    $supplierId = SupplierMap::getBySku($item->getProductId());
    $supplierOrders[$supplierId][] = [
        'sku'      => SupplierMap::getSupplierSku($item->getProductId()),
        'qty'      => $item->getQuantity(),
        'address'  => $deliveryAddress,
        'order_id' => $orderId,
    ];
}

foreach ($supplierOrders as $supplierId => $items) {
    $supplier = SupplierTable::getById($supplierId)->fetch();
    SupplierGateway::send($supplier, $items);
}

SupplierGateway::send() sends HTTP request to supplier API, forms letter, or XML for EDI — depending on order_method.

Receiving tracking number from supplier

Supplier sends tracking number back — via webhook to your site endpoint or API response. Create public handler /bitrix/supplier_webhook.php, which:

1. Receives supplier_order_id, tracking_number, carrier
2. Finds related Bitrix order by supplier_order_id via bl_supplier_orders table
3. Writes tracking number to custom order fields (UF_TRACKING_NUMBER, UF_CARRIER)
4. Sends customer email with tracking number via \Bitrix\Main\Mail\Event::send()
5. Changes order status to "Shipped to delivery"

Deadline control

Agent every 6 hours checks orders to suppliers older than lead_time_days. If supplier didn't send tracking number in time — creates task for manager via CRM or sends notification to administrator.
