Some transactions are failing with “Failed event verification”

    On my website most donation transactions go through fine, but in a small percentage of cases I get an error. On the frontend it says “There was an error processing the transaction. Please contact the administrator”.

    On the back-end, each time there is such an error, I get two logfiles (logged at the same second). One (uncaught exception) has the description “Failed event verification” and one (payment) has the description “Failed webhook event verification”.

    When looking into the logfile, the error is happening in /wp-content/plugins/give/src/Controller/PayPalWebhooks.php on line 88.

    I am sure that the people trying such donations are not entering invalid information.

    What can I do? Thank you.

    Hi @alfy40,

    Glad you reached out. I can help here.

    The “Failed Event Verification” can usually be resolved by disconnecting and reconnecting PayPal. You need go to Donations > Settings > Payment Gateways > PayPal and clicking the “Disconnect” link in “PayPal Connection”.

    In order to process payments over Paypal’s API, third parties (like GiveWP) have to store what’s called a “token” and send that token along with the payment information. The token verifies that the application is allowed to do transactions over the API. If Paypal is unable to verify the token it will throw that “Failed Event Verification” message.

    If disconnecting and reconnecting PayPal does not fix the issue, I’d recommend reaching out to them. The form on our site at https://givewp.com/paypal-onboarding-reports/ goes directly to them, to an email that they claim is staffed by folks familiar with the issues, who can help.

    Let me know where you stand after disconnecting/reconnecting. Have a good day!
