Create and Send Order

Summary

Create an order and send its payment request in one call, with idempotency protection.

Prerequisites

Authorization: Bearer w91_live_xxx
Content-Type: application/json for JSON requests

Related documentation

Creates an order and sends its payment request in a single call. The two steps run sequentially; use the create body with a nested send object.

POST/api/v2/orders/send

Create an order and send its payment request.

cURL

curl -X POST "https://graph.whats91.com/api/v2/orders/send" \
  -H "Authorization: Bearer w91_live_xxx" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: restaurant-checkout-2092" \
  -d '{
    "sender_id": "919999999999",
    "recipient": { "phone": "919876543210", "name": "Restaurant Guest" },
    "items": [
      { "product_uid": "prod_masala_dosa", "quantity": 1 },
      { "product_uid": "prod_filter_coffee", "quantity": 2 }
    ],
    "currency": "INR",
    "total_amount": "300.00",
    "send": {
      "config_uid": "pcfg_manual_upi",
      "body_text": "Please review and pay.",
      "expires_in_minutes": 30
    }
  }'

Created, then send failed

{
  "success": false,
  "message": "The 24-hour chat window is closed. Select an approved payment template.",
  "error_code": "PAYMENT_TEMPLATE_REQUIRED",
  "details": {
    "templates": [],
    "order_uid": "ord_abc123",
    "order_status": "draft",
    "send_retry_endpoint": "/api/v2/orders/ord_abc123/send"
  },
  "metadata": {
    "apiVersion": "v2",
    "requestId": "request-uuid"
  }
}

Warning

If creation succeeds but sending fails, the draft is deliberately not rolled back. Correct the send input and call the endpoint returned in details.send_retry_endpoint. Do not call create-and-send again without the original idempotency key, or you will create a second order.
