Event Wire Security

Each external system that uses Event Wire must identify itself by using an external ID in every processtrxn or gettrxnstatus call. Event Wire checks whether the external ID has been set up in the Event Wire Control Center. If not, the request is rejected.

However, anyone who knows a valid external ID, the landing page URL, and its parameters can issue a call to Event Wire. To minimize the exposure of these values, you can use a secure connection to call Event Wire. To do this, establish an SSL (Secure Sockets Layer) session, whereby all data is encrypted before being sent across the network.
