About QuickBooks Payments
Setting up QuickBooks Payments
Access the Intuit developer app and create a new QuickBooks payment application
Choose QB Online and Payments, add the name for the app and click Create app.
Once the app is created go to My apps from the dashboard and select the created app, then go to Production Keys & OAuth section and select OAuth 2.0 Playground.
Once there select the production environment and check the Payments checkbox, then click Get authorization code (Step 1)
Once you get the authorization code, you can get the OAuth Token (Step 2)
In step 3, select Payments again and Get tokens from Step 2.
Once you retrieve the tokens the system will populate the rest of the fields which you can then paste back to QuickBooks integration on Nexudus.
