Our company wants to build its own application and integrate it with the data in quickbooks like product , wants to know how to find our API docs and links

Welcome to the Community space, @yomnaawd0. I'd be glad to help find your API docs and links.

Since your company wants to integrate with the data in QuickBooks like products, we have a separate forum that handles API concerns. That said, I'd recommend setting an account and post your question from there. This way, our developers can provide you with the access token to get authorized and guide you in finding your API docs and links. 

Here's how:

1. Go to the Intuit Developer page.
2. Choose QuickBooks Online under What do you need help with?
3. Click Ask a Question.
4. Log into your existing Intuit Developer Account or create a new one.
5. Enter the details of your concern.
6. Select Ask.

Also, you can utilize the helpful API topics by going to the API Docs & Tools menu. Then, select QuickBooks Online and choose API Explorer.

Additionally, I'll be adding this Community resource if you've got other QuickBooks concerns as setting up payments, managing your income and expenses, running reports, etc. Please refer to this article for more details: Community help articles.

If there's anything I can help you with, just let me know by leaving a comment below or post again. Thank you, and have a great day ahead.
