Hi
using .net and version 1.9.1 of PayPal SDK. Everything has been working fine for years then today I got the error:
PayPal.PayPalException: Unable to verify the certificate(s) found at https://api.paypal.com/v1/notifications/certs/CERT-360caa42-fca2a594-8079afec
When PayPal calls the Webhook we have to check if it is valid:
var isValid = WebhookEvent.ValidateReceivedEvent(apiContext, requestheaders, requestBody, webhookId);
I believe this is the event causing the issue. Somewhere in this API call PayPal calls:
PayPal.CertificateManager.GetCertificatesFromUrl(String certUrl)
The string I guess is the one at the top and the result is a revoked certificate.
Can anybody please tell me why this has started happening? Happens in live and sandbox btw.
Thx
