QuickBook Invoice Creation Error: Bad request - please check your parameters

[vicrost]

Describe the problem/error/question

I am creating a workflow that automatically sends an invoice using quickbooks online from a google form submission. The flow:

• Trigger when a new row is added to the form submissions sheet
• Get all existing customers from quickbooks
• Check if the form submitter is an existing customer
• If they are, create and send an invoice to that customer
• If not, create a new customer and send the invoice

The issue I am facing atm is in the invoice creation node. When I try executing the node, I get the following error (under the error heading). I also get the following error in the customer id field:

What is the error message (if any)?

Error code

Is that customer “Active” in QuickBooks? (Check the customer record in QBO.)

Try one (or both) of these quick fixes

Map the real Customer ID (or DisplayName), not BillAddr.Id

1. • In Create an invoice → For Customer Name or ID, use the ID from your Get many customers node result:

     {{$node["Get many customers"].json["Id"]}}
     
     

     or, if you matched by name:

     {{$node["Get many customers"].json["DisplayName"]}}
     
     

   • If the customer doesn’t exist or is inactive, first Create Customer (or reactivate), then pass that new Customer.Id into the invoice.

2. Provide a valid active Item on the Line

   • In Line → Item Name or ID, set an active Product/Service (e.g., a “Service” item you already have in QBO):

     {{$json.ItemRef.Id}}   // or hardcode the active item ID to test
     
     

   • If you don’t have one, create a simple “Service” item in QBO and use its Item.Id.

   • Only using Amount + Description (with no Item) often fails; QBO wants an item reference.

Thnx. i went with option 1, used the real customer ID and it worked. Though I was pretty sure I tried it before as well but it didn’t work but all good now.
