Whmcs Functions Add To An Existing Api For Owp

Hello,

For this project, i search somebody who can write a simple code to an existed API between WHMCS and OWP. So basically i need 2 functions.

First is: When an order is done by whmcs the API must automatically pick a free ip from the pool ip in OWP and assign it to VPS.
Second is: When a customer make order of a VPS need to add a drop down menu with OS’s list from OWP.

Thank you in advence.

PS:Need it ASAP
