NS0739 Sync Error in NetSuite Integration

If you see the error:

NS0739 Sync Error: Unexpected error when logging in with tokens.

This usually means the NetSuite tokens were created with incorrect permissions or are not formatted properly.

When the token configuration does not meet NetSuite’s requirements, Expensify cannot authenticate and syncing fails.

Why the NS0739 Sync Error Happens in NetSuite

The NS0739 error typically occurs when:

• The generated access tokens do not have the correct permissions in NetSuite.
• The SOAP Web Services permission is not set correctly on the integration role.
• The token is formatted incorrectly, especially in a Sandbox environment.
• The account ID or role configuration does not match the token setup.

If the token configuration does not align with NetSuite’s requirements, the login attempt will fail.

This is a token permission or formatting issue, not a bundle update or general credential issue.

How to Fix the NS0739 Sync Error

Follow the steps below to verify permissions and token formatting.

Confirm SOAP Web Services Permission on the Integration Role

1. Log in to NetSuite as an administrator.
2. Go to Setup > Users/Roles > Manage Roles.
3. Locate and click Edit for the Expensify Integration role.
4. Click the Permissions tab.
5. Scroll to the Setup section.
6. Confirm SOAP Web Services is set to Full.
7. Click Save if changes were made.

After updating the permission:

2. Select your Workspace.
3. Click Accounting.
4. Click the three-dot menu next to the NetSuite connection.
5. Click Sync Now.

Confirm Token Formatting in NetSuite Sandbox (If Applicable)

If you are connected to a NetSuite Sandbox environment, confirm the account ID and token format are correct.

Correct format example:

• 12345678_SB1

Incorrect format example:

• 12345678-sb1

Sandbox account IDs are case-sensitive and must use the correct capitalization and underscore format.

After confirming the format:

1. Update the account ID or token details in the Workspace if needed.
2. Click Save.
3. Click Sync Now.
