Hello Srebezaw,

Integrating third-party applications to QuickBooks Online requires the assistance of the third-party's support team. I'd recommend contacting them about this. They'll be able able to determine whether they can do the integration process successfully or not.

We can also go to the Apps menu within QBO or go to this website for the supported applications: https://apps.intuit.com/app/apps/home.

Feel free to get back to us if you need anything else.
