Hi, I need to create a dummy account for external party to link our new development with API, anyone can help

I recognize how important it is to create a dummy account for your new development with API, sharonang. I'm here to ensure this gets taken care of.

I'd suggest posting directly to our Intuit Developers website. This is where developers engage with others to discuss programming or API concerns.

Here's how:

1. Go to the Intuit Developer website.
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 your concern. 
6. Click Ask. 

You might also want to check our QuickBooks Online learning guides. This includes help articles, video tutorials, and others to get a better grasp of the product.

The Community has your back should you need assistance with any QuickBooks concerns, sharonang. Have a great day.
