This document is intended for users, who wish to develop applications using the
eTranzact WebConnect™ Gateway for processing payment or confirming payment status.
The gateway can be accessed via HTTP protocol by submitting values using POST
method to the eTranzact WebConnect™ API. WebConnect™ will only process payment
from a web site or domain name that is registered on its network. i.e. requests are
validated against source domain name.

• Using HTTP Protocol API and submitting values by POST method
• Using Web Services.
