Error 350 - Continues to occur although we have reconnected several times. How do we fix this issue?

As of a couple of weeks ago we continue to get Error 350 regardless of our reconnecting to the bank.  How do we fix this long term?

Hi there, @E2MBeancounter. I agree with what @SIAB mentioned. Opening QuickBooks Online (QBO) in an incognito/private window helps bypass cached data or old login tokens that may block the new bank authorization. Once you're in the private window, reconnect your bank so that QBO can establish a new connection.

 

You can also check your bank's website for any alerts or updates, as changes on their end can cause the 350 error to continue.

Try opening your QBO account on any private/incognito browser.

This has not been solved.  I spoke with a QuickBooks rep this afternoon who admitted that there is a known issue with Bank of American and QuickBooks subscribers with multiple company accounts and multiple bank accounts.  My supervisor who is the account holder will now have to contact QB to screenshare and troubleshoot it together.  I sure hope they can come to some type of resolution.

Thanks for the update with more specific details, E2MBeancounter. In case this requires more time to resolve, consider manually uploading transactions from your affected accounts. This way, you can continue working on your books while waiting for a fix.

 

Please note that once the connection is restored, those same transactions may download automatically. If that occurs, be sure to exclude them to avoid duplicates.

 

Feel free to return if you have follow-up questions.

We are unable to resolve our Error 350 issue with the American Express account.

I have walked through the steps by clicking fix now as well as Link account:Manage connections and then selecting Sign in to American Express.  I receive a message that it requires account owner approval, see attached screenshot. 

 

I have walked through the steps with the owner of the AmEx account, yes he has full authority in qbo and amex, and he gets a never-ending spinning circle.

Since the standard hasn't resolved the error you experienced, I'd like to ask if there's a specific option in the error message you encountered that says "Send a request"? This will email the original user who set up the bank connection to re-establish it.

 

If none, I suggest disconnecting and reconnecting your American Express account in QuickBooks Online (QBO). Disconnecting removes the old broken token, and reconnecting generates a fresh one.

 

To disconnect it, you'll need to go back to your bank feed in QBO. Locate the American Express bank account, and click the pencil icon. Select Disconnect account. After that, reconnect the bank account by clicking Link account.

I am the person that connected to American Express in QBO; as I recall our previous CPA firm walked me through the steps in May of 2025.  We are no longer in contact with that firm and we purchased QBO plus directly from intuit and not purchase through them.

 

The error message did not have an option to send a request.

 

I disconnected the account per your instruction and when I try to connect I get the same error from AmEx as before.
