Good to see your post today, joy-mairanga-tur.

I want to direct you to the right support that can answer questions about API integration.

We have a separate online forum called  Intuit Developer Community where you can post this type of question. Our team of developers can provide insights about connecting internal ERP with QuickBooks through API.

Get back to me if there's anything I can help you with. I'd be happy to assist you further. Enjoy the rest of the day.

Did you develop your own ERP system or purchase a specific solution? You may develop your own connector if require. For the time being, utilize a 3rd party migration tool.
