Adding your eCommerce/Order IDs to Transactions

❗️
Caution
The custom_id field is required for schema validation but you do not have to enter a value.

To add this ID, add the custom_id field to your requests. This ID is returned by the API in subsequent responses.

The following example shows the field in a transaction object in a request:

"transaction": {
    "currency_code": "EUR",
    "custom_id": "Order_123456",
    "buyer_name": "Kate Smith",
    "ship_to_address": {
      "street_name": "1 Main Street",
      "address_detail": "City West",
      "city": "Dublin",
      "postal_code": "PT1 2345",
      "country_code": "IE"
     },   
    "transaction_lines": [
        "product_class": "P",
        "quantity": 1,
        "description": "Coat",
        "amount": "62.99",
        "ship_from_address": {
          "country_code": "DE"
        },
        "product_cn_code": "0810000000"
      }
