AMEX sync stopped working


The AMEX sync stopped working almost 3 weeks ago, showing error 340.  I reported it to Intuit and a case was opened and linked to an ongoing case started March 12, 2019. So far, there has been no fix. In the CoA, there is no longer an online banking connection. The agent I spoke to said there had been several hundred inquires for this same issue. Anyone else experiencing this, and if so, what is Intuit telling you? I have a very unhappy client with hundreds of transactions waiting to sync.

Hi, ghyland.

I'm here to provide you additional information about the error 340.


We're receiving reports that other users are getting this error as well and we would like to inform you that this has already been escalated to our Online Banking Team. Although we don't have a specific time frame as to when and how this will be mediated upon, rest assured that this is being looked into.


As soon as an update is received I will be happy to update this thread and let everyone know.


As much as we’d like to provide you a workaround so you can update your bank transactions, using our WebConnect feature isn’t recommended since it will not bring in transactions as well.

Thank you for your patience. I'll keep you posted if there's an update, have a good one.

This issue (340 error) started March 4th here and we are still waiting for a fix.   QB keeps saying they are still working on it.   Very unhappy at my bookkeeping firm.

Is there any progress on this issue? Or a work around that doesn't involve manually entering transactions? Ditching AMEX is starting to look appealing.

I am having this issue (had it in Jan/Feb then it started working again). I haven't had any transactions downloaded from Amex Open since mid March. Doing an update doesn't help or do anything for my Amex card. All other banking and credit card connections are working fine.


This is what Amex Open says.

Hello, @mbrando.


I've checked that we have a new investigation about the American Express Credit Card account not syncing or connecting. Since refreshing your account didn't fix the issue. It would be best if you can get in touch with our Support Team to check and verified this further.


Once verified that you're one of the affected users in this investigation, our team will add you to the list of affected users and automatically receive an email notification with the latest updates.


On the other hand, to stay updated with the QuickBooks news and updates, you may visit our QuickBooks blog.


Feel free to add a post/comment below if you have any other banking questions, I'd be glad to help you. Wishing you the best!
