When attempting to authorize a transaction with the Orbital gateway I see the error “HTTP protocol error. 412 Precondition Failed”
When processing transactions against the production server, your IP address must be registered with the Orbital Gateway. Any activity presented on an IP address that is not registered with the Orbital Gateway will result in an HTTP 412 error from the server.
You will need to contact Orbital to make sure the account that you are specifying is configured for production.
If you’re testing, make sure to set the GatewayURL property to “https://orbitalvar1.paymentech.net/authorize”
