I'm here to ensure that you'll get pointed in the right direction to get the issue taken care of.
If you're referring to integrating a third-party application with QuickBooks Online, you may reach out to our Intuit Developer. This team is the best resource for such concerns as they are the experts on how the application and the program work.
On the other hand, if you have any issues with your transactions that need to be uploaded or saved, you may contact our Customer Care Team. The best way to reach our support team is to sign in to your account, select the Help icon on the top right, and then Contact Us at the bottom of the panel.
I also have here a link that you can visit about some help articles that contains information about navigating QBO with its great features: ZA QuickBooks Help Articles.
