Create a QuickBooks Online App and Connect OOMOL

Open OOMOL App Connections, find the app, and choose Add account. Follow these steps when asked to provide your own app credentials. You will need an account that can create or manage the app on the provider’s website; ask your administrator for help if you cannot access those settings.

1. Create or open the app

1. Sign in to QuickBooks Online.
2. Create an app in the Intuit developer portal and choose Accounting. Open Keys & OAuth.

2. Set the callback URL

In the account form, copy the full Redirect URI. If an authentication method is shown, choose OAuth2. Paste it into Redirect URIs in the provider’s app settings and save. Keep the address unchanged, including its path and trailing slash.

3. Save the credentials

Choose Production for a real company or Development for a sandbox company. Complete the portal’s requirements for production access, then copy both credentials from the same environment.

In OOMOL’s OAuth client configuration, paste Client ID into Client ID and Client Secret into Client Secret, then save.

4. Connect your account

1. In OOMOL, open the connection settings and continue with OAuth2.
2. In OOMOL’s Environment field, select production for Production keys or sandbox for Development keys. Sign in to Intuit and select the matching company.
3. Return to OOMOL and confirm that the account is connected. Read the company information and check the company name.

If you cannot connect

If the company is missing, check that you used the correct environment and an account permitted to authorize that company.
