Populate Custom Data Field in Sales Order Line from Third Party API

Hello @TharidhiP, please share your HTTP request with us. If you already have your custom field located in your custom endpoint, all you need to do is send a POST request to the {baseUrl}/auth/login first, and then send a PUT request to the baseUrl/{YourCustomEndpoint}/{YourCustomField}. Use OrderType and OrderNbr for the header section, and OrderType, OrderNbr, and LineNbr for the Details array in the JSON body.

 

{
    "OrderType": {
    "value": "SO"
    },
    "OrderNbr": {
    "value": "{YOURORDERNBR}"
    },

    "Details":
    [
     {  
        "OrderNbr": { "value": "YOURORDERNBR"},
        "OrderType": {"value":"SO"},
        "LineNbr": {"value":1},
        "UsrMAINParentKitID" : {"value":{YOURID}}
      }
     ]
}
