ECHO's Secure Payment Gateway

The ECHO Payment Gateway service is built around the same set of industry-standard, open interfaces that enable World-Wide Web communications. All transactions use the following well-defined and well-understood technologies:

• HyperText Transfer Protocol (HTTP)
• Secure Socket Layer (SSL) Encryption
• Common Gateway Interface (CGI)

The ECHO Payment Gateway receives messages as if they came from a Web browser. ECHO provides the Web server and the ISP Partner provides the Web client. The API interface between the ISP and ECHO is the standard HTTP/1.0 (or HTTP/1.1) protocol using Secure Sockets Layer (SSL) encryption. The ECHO Payment Gateway recognizes and processes both GET and POST methods.

Transactions are broken up into delimited fields. A transaction is transmitted either in the request header for the GET method, or following the request headers for the POST method.

Please refer to our Gateway Interface Specifications for the complete story.
