NS0739 Sync Error in NetSuite Integration

If you see the error:

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

This means NetSuite rejected the authentication attempt using access tokens.

This error is usually caused by incorrect token permissions or formatting issues.

Why the NS0739 Sync Error Happens in NetSuite

The NS0739 error typically occurs when:

• The access token was created with incorrect permissions.
• The Expensify Integration role does not have required permissions.
• The SOAP Web Services permission is not set to Full.
• The token is formatted incorrectly, especially in a Sandbox environment.
• The token is tied to the wrong user or role.

If the token configuration does not meet NetSuite’s requirements, the login attempt fails.

This is a token and role configuration issue, not a bundle update or general login credential issue.

How to Fix the NS0739 Sync Error

Follow the steps below to verify role permissions and token formatting.

Confirm SOAP Web Services Permission

1. Log in to NetSuite as an administrator.
2. Go to Setup > Users/Roles > Manage Roles.
3. Select Expensify Integration.
4. Click Edit.
5. Scroll to Permissions > Setup.
6. Confirm SOAP Web Services is set to Full.
7. Click Save if changes are made.

After updating the permission, return to the Workspace and retry the sync.

Confirm the Token Is Assigned to the Correct User and Role

1. Go to Setup > Users/Roles > Access Tokens.
2. Locate the token used for the Workspace connection.
3. Confirm:
   • The User is correct.
   • The Role is Expensify Integration.
4. If needed, generate a new token tied to the correct user and role.
5. Update the connection credentials in the Workspace.

Confirm Sandbox Token Formatting (Sandbox Only)

If you are connected to a NetSuite Sandbox environment, confirm the account ID is formatted correctly.

Correct format example:

• 12345678_SB1

Incorrect format example:

• 12345678-sb1

Important:

• Sandbox account IDs are case-sensitive.
• Use an underscore (_) before the sandbox identifier.
• Do not use a dash (-).

After correcting the format, update the connection and retry the sync.
