Visual Basic 6.0 to Gunbroker API integration

I need Visual Basic 6.0 code to interface with GunBroker's API. The code should have subroutines to download and post inventory and orders on GunBroker. Optionally, the code can be written using Chilkat API code (a set of cross-language, cross-platform API algorithms). The GunBroker API documentation can be found at https://api.gunbroker.com/User/Help. Chilkat examples for VB6 are at https://www.example-code.com/vb6/default.asp.
