EE's Quickbooks Payment Method rejected after Intuit's 11FEB2020 deadline

Quickbooks Credit Card processing is being rejected due to non-compliance with Intuit’s new authentication rules. I disconnected on the Payment Methods page to re-authenticate, but Quickbooks refuses. It states that the Event Espresso plugin is no longer compliant with their new Authentication requirements enacted on 18DEC2019.

Quickbooks forwards connection button authentications to their announcement page URL:

Intuit claims that Espresso must update to conform to their rules before re-authenticating to Quickbooks Merchant Account.

Are you seeing this authentication error from others using EE’s Quickbooks Payment Method? Does the Quickbooks Payment Method Plugin need to be updated by EE?

I can not re-connect to Quickbooks payment, the gear turns than a pop-up presents the above Intuit URL declaring the February 11th deadline. My E-commerce is down and I am not conducting business until a resolution is found.

I replied with an email to you about how to get up and running with OAuth2.0 using the Quickbooks gateway. Here are the instructions in case you didn’t get the email:

  1. Log into your account at
  2. Click My Apps
  3. This will list your apps, if you have an app with OAuth Type: OAuth2.0, you’ll click through to get the app’s settings and proceed to step 4; If you do not have an app with OAuth2.0 you can click the button to Create an app and follow the prompts to create a new app, then proceed to step 4
  4. Click Keys and OAuth
  5. Copy the Client ID and Client Secret to your clipboard; Make sure the Redirect URI points to your site’s home page
  6. Log into your WordPress dashboard and go to Event Espresso > Payment Methods > Quickbooks
  7. Change the OAuth version setting to OAuth2.0, then paste in the Client ID & Client Secret into their respective fields
