Supported operations can be submitted by using the HTTP/HTTPS Web protocol.
The overall operations meet a request / response model, where a client process establishes a connection against the front end to our transactional server to submit a request that have to be applied to a resource. The server replies with either a single record response, a multiple record response or with an error indication. Only one request can be submitted over a single connection.
Successful transactions return the requested data, if exits, response code, response description and the fee for the request.
Connectivity issues can be hidden by the transport used as done by SSL or HTTP but still this point requires attention when going through the Internet as several routers and firewalls are in between.
All API calls require a Shared Secret key that can be generated from API Settings page.
