I want quick book api to manage my user by that they only can see my inventory not any information

Thanks for checking in with us, userakshaytomar-com.

The option for the users to access only the inventory part of the account is unavailable in QuickBooks Online (QBO). You'll want to post this question directly to our Intuit Developers website. This is where developers engage with others to discuss programming concerns. Here's how:

1. Go to this link: https://help.developer.intuit.com/s/.
2. Choose QuickBooks Online under What do you need help with?. 
3. Tick Ask a Question. 
4. Log into your existing Intuit Developer Account or create a new one. 
5. Enter your concern. 
6. Click Ask. 

You can also utilize the API Docs & Tools menu on the Intuit Developer's page to possibly execute the said process in QuickBooks. Feel free to visit our Manage Your Account page for more insights about managing your Intuit account.

I'll be right here to continue helping if you have any other concerns or questions about QuickBooks. Assistance is just a post away.
