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 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.
• The SOAP Web Services permission is not set correctly on the integration role.
• The token is formatted incorrectly in NetSuite.
• A Sandbox account ID uses incorrect capitalization or formatting.

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 login credential issue.

How to Fix the NS0739 Sync Error

Follow the steps below to verify permissions and token formatting.

Confirm SOAP Web Services Permission

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.

Confirm Token Formatting for NetSuite Sandbox Accounts

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

2. Click Save.
3. Click Sync Now.
