Linking an Estimate to an Invoice via QuickBooks API
Hi everyone,
I'm currently working with the QuickBooks Online API and facing issues linking an existing invoice to an estimate or create an invoice directly linked to an estimate. I understand this should be done using the LinkedTxn field, but I’m unsure of the exact API request format as their is no error message returned but the field LinkedTxn is empty.
I already contacted QuickBooks support, but their suggested solution didn’t work. (I can provide the exchange if needed)
Could someone please provide a complete example of the API calls (JSON request bodies) for:
1.Creating an invoice linked to an existing estimate.
2.Updating an existing invoice to link it to an estimate.
Including the required headers, endpoints, and a typical request payload would be extremely helpful. I’m also curious about any specific permissions needed for this operation to work properly.
Thanks in advance!
Best,
