- Configure your webhook URL to request a client certificate during the TLS handshake.
- Validate the certificate we sent against the root you have installed.
Validation & Renewal
Our client certificate is renewed regularly and is in line with best practice. You should never configure your server to expect an individually specific certificate. We recommend that you use the following aspects to validate the certificate:
- The Subject Common Name of the client certificate - this always contains
Payment Status Event Sender.
Info
For the Try environment it returns Payment Status Event Sender (secure-test).
- The root of the signing chain - this has the Common Name
UKDC1-PC-PKI02. The root may occasionally change, and you are notified of any changes.
Example Nginx configuration
server { listen 8443 ssl; # Make sure the certificate is signed by a trusted CA ssl_certificate trusted_ca_signed_certificate.crt; ssl_certificate_key private.key; # Mutual TLS / Specify the allowed CAs for the client cert # This is where you put Worldpay's root certificate from the documentation ssl_client_certificate client_cert_cas.pem; ssl_verify_client on; ssl_verify_depth 3; # Mutual TLS / Client Cert Auth - client cert has known subject if ($ssl_client_s_dn !~ "Payment Status Event Sender") { return 403; } # Mutual TLS / Client Cert Auth - client cert issuer has known subject if ($ssl_client_i_dn !~ "UKDC1-PC-PKI02") { return 403; } location / { proxy_pass http://localhost:8080; } }
