Paypal (async?) error

Author	« Topic »
Dermontti Advanced Member USA 165 Posts	Posted - 06/06/2024 : 07:56:57 Hello, We are currently on version 7.6.4 This seems to be somewhat of an edge or corner case, but we had a customer get an error on thanks.asp from paypal. We placed a similar order and were able to replicate the error multiple times, but not every time as it seems sporadic. When we investigated, it looked like there was a delay from Paypal in sending the IPN (a temp heavy server load and que? I am guessing Paypal may have an auth an webhook/ipn api that is separate, or at least a separate response), however, the payment went through right away. Based on my experience, I would say this could be an async code issue with the Paypal API sending it late, or the thanks.asp page javascript tries to execute sync and if the Paypal API has high traffic and a slow response, it throws an error since the thanks.asp page has still not received the IPN, but starts running on a successful initial response. Is the handling for the paypal IPN async? If this is not the issue, does anyone have any idea what it would be? Thanks!

If so, are you able to update to PayPal Checkout as the old integrations are no longer supported by PayPal.

Vince Administrator 42769 Posts	Posted - 06/13/2024 : 02:43:31 Hi Dermontti Everything has now moved to PayPal Checkout including PayPal Express, Direct (which is now Advanced Cards) and Standard. PayPal Checkout also includes local payment methods. But the old API’s are now deprecated and PayPal won’t support them. There have been improvements with PayPal Checkout in the latest releases.

Dermontti Advanced Member USA 165 Posts	Posted - 06/13/2024 : 05:38:01 Ok thanks, but I am still confused. We do not want Paypal express, so what do we choose to make it the non-deprecated version and still work as intended?
Vince Administrator 42769 Posts	Posted - 06/14/2024 : 02:41:58 Hi Dermontti If you go through the PayPal Checkout setup wizard in the ECT admin - Payment Providers page. Then you can choose to enable Express or not or can have no cards either and just PayPal. But Checkout is the basis for it all.

So the non-Express flow is just where you do enter your customer details as normal and you'll see the PayPal payment options on the page after that.
