I’m having an issue with the QuickBooks Online API where none of my invoice custom fields are being returned. I created around 7 custom fields in the QuickBooks UI under Settings → Lists → Custom Fields, and all of them are enabled for Sales and Invoices. However, when I retrieve any invoice through the API, the CustomField array is always empty. For example, when I call the invoice endpoint using my realm ID and minor version, the API returns all regular invoice details but the CustomField section is completely empty. Can someone confirm whether invoice custom fields should appear in the API response, and if they should, what steps are needed to make them show up?
