Good day, Tooba1.
Let me get you to the right support team that currently handles QBO API concerns. We have Developers Team that knows how to pull module lists for purchases or incomes using the access token in API.
Here's how you can reach them:
- Visit this link: https://developer.intuit.com/app/developer/homepage.
- Scroll down, at the bottom click Contact us under the Intuit column.
- Select a topic from What do you need help with?
- Click As a Question and follow on-screen instructions.
You might want to visit the following link to become more familiar with the features and functions of QBO: Help Articles.
I'm looking forward to hearing this being resolved. Let me know if you have other QuickBooks questions and I'll be here to help. Wishing you a good one.
