Hi Bastien!
Welcome to QuickBooks Community. Let me share some details about third-party applications.
There are hundreds of third-party applications that can be integrated into QuickBooks Online. However, please note that they have their own ways of linking their platform to QuickBooks. It's best that you reach out to Petpoojas' support to confirm if this is possible and so that they can share the steps on how to do it.
You'll want to visit the Apps menu on your QuickBooks Online. From there, you'll see some of the lists of supported third-party applications.
I added this link if you need help in linking your bank to QuickBooks Online and how to categorise the downloaded transactions:
The Community is always here to help you if you have other concerns. Have a great day!
