Problem Description

I'm looking for someone to help me integrate the Quickbooks online API with an example Next.js v14 application. The node.js oauth SDK provided by Quickbooks doesn't seem to work with next.js due to a naming conflict in a node module.

You may be able to use the node SDK: https://www.npmjs.com/package/node-quickbooks for API calls, but the OAuth setup may need to be custom.

Acceptance Criteria

• Use Next.js 14.0.3 sample app with app router
• Ability to fetch and refresh the OAuth token from Quickbooks in the application.
• Ability to call the Quickbooks Online API with the OAuth token
• Ability to create a purchase order using the Quickbooks API with a Sandbox company (info here: https://developer.intuit.com/app/developer/qbo/docs/develop/sandboxes)

Technical Details

• Use Next.js 14.0.3 with app router
• Create a reusable file/service which can handle the Quickbooks Online Oauth and API calls.
