I'm using Zapier as a medium for creating invoices, but every time I test the step, it uses a deleted default product/service instead of the product ID that I specified.

Good day, management4.

When creating invoices with Zapier, it's best to reach out to them. They can walk you through the steps on a proper way of creating it. They can also check why it uses the deleted product/service.

You can get their contact details through this link: https://apps.intuit.com/app/apps/appdetails?shortName=zapier&locale=en-us.

Get back to me anytime of you have any more questions I can help. Have a great day!
