Registration Approved message not sent after a failed payment

Someone registered and paid for one event using a credit card through PayPal Commerce. They received the registration approved message for that event. Then they registered for a second event and said that the payment wouldn’t go through for that same credit card, so they used their PayPal account, which was successful. Gateway response for the failed transaction was “Order data in wrong format.” A payment failed message was sent, but no registration approved message was sent for the second event.

Can you give us more information on the problem.

for the 1st failed payment, what error did they received when they did use their credit card?

Also in paypal, Were they able to capture the error message?

i think its right that there will be no registration approved message since the payment was failed.

Can you tell us what are the payment method you have in your site. Tell us also your system information.

If you can also send screenshot of the error message that would be great.

Can you also check your log?

The error that she received when trying to use her credit card to register for the second event was “Order data in wrong format.”

There was no PayPal error. Her PayPal transaction went through and there should have been a registration approved message after that transaction.

We only have PayPal Commerce enabled.

Thank you, we’re trying to figure out the problem. Is this isolated case? or that happen in also in your past registration?

For now, you can trigger the approved message to your customer.

We will look more on this, we might need your log-in information if we cannot replicate the issue. We will keep you updated.
