h1. Programming Guide for Batch Program

> Refer to [[Programming Guide]] if integrating in other environment, e.g. web app

All of the APIs mentioned below will not invoke the DP web services at all. Instead it will insert record into [[Specification#DP_INTERFACE|interface table]] and then those records will be picked up by a specific batch program and send it to DP on daily basis.

The binary or source files of *dp-client*:

> [[wiki#SCM|SCM]]

Demo application of *dp-client*:

> There is no demo application for these APIs but these API usage is very similiar with the one that mentioned in [[Programming Guide]]
