Hello @vivekkec120,

We have a separate Community you can get in contact with about associating your POs and bills created via the QBO V3 API. You can click and start the same conversation through this link: https://help.developer.intuit.com/s. We have several developers, engineers, and programmers who can help link your transactions.

Feel free to get back to us here in the QuickBooks Community if you have any other concerns.
