QuickBooks vs. American Express Syncing – What’s Really Happening Behind the Scenes?

When you connect AMEX to QuickBooks, the two systems talk using secure APIs (Application Programming Interfaces). But if either side makes a small change—like a security update or new login procedure—those APIs can get out of sync. QuickBooks depends on uninterrupted access to your AMEX data stream, and even a brief interruption can cause syncing to fail.

Here’s what usually goes wrong:

API Timeout – Slow internet or a busy server may interrupt the sync process.

Token Expiration – Your login session expired without warning.

Access Revoked – AMEX may auto-disable third-party access after security reviews.

Understanding this helps you react quickly when things go wrong.

FAQs – QuickBooks American Express Not SyncingQ1: How often should I sync my AMEX account in QuickBooks?

Q3: Is this issue more common in QuickBooks Desktop or Online?

It can occur in both, but it's slightly more common in QuickBooks Online due to browser dependencies.

Q4: What if AMEX no longer supports direct sync?

You can still import transactions manually via .CSV or .QBO files.
