PayPal rest API hangs (LIVE not sandbox)

[deansatch]

My site uses the rest API with v1/payments/payment - I've been told by a customer that after redirecting to paypal it hangs then finishes on a white screen. Any error on my site wouldn't result in a white screen...its a laravel site and has a custom page for all error codes including 500.

When I check the paypal log file I see the following on an example which failed:

[25-08-2017 12:48:07] PayPal\Core\PayPalHttpConnection: INFO : POST https://api.paypal.com/v1/oauth2/token

[25-08-2017 12:50:24] PayPal\Core\PayPalHttpConnection: INFO : Response Status : 201

On a successful one the second "v1/payments/payment" contains "payment/PAY-{ID}"

Any ideas what could be happening here? I should also mention that this is quite rare as many other orders go through fine.

I don't know why this is showing in sandbox category...I didn't choose that

Hi, can you send a specific log for a payment that "hangs"? In REST you first create the payment with /v1/payments/payment and then you execute it with /v1/payments/payment/PAY-123ABC456DEF789GHI/execute.

If you can send a log with either the payment creation or execution, the date it was attempted and the full response you received I can have a look in our logs.

I am also having this problem since February 2019.

I was not sure if it was allowing communication so I did a test I knew would fail when the amounts do not add up, so it is communicating:

However when everything DOES add up, I process the order and my credit card is indeed charged and the funds added to paypal, so paypal is receiving the information and charging but not passing back?

Any help is greatly appreciated.
