How to apply a promo code via an API request

Two API requests are required, because a promo code can only be applied to a cart.

To apply a promo code:

1. Add services to cart with the <itemtype>.order.param function. Example of a request:

   <platform_address>?clicked_button=finish&datacenter=1&func=vds.order.param&licence_agreement=on&ostempl=ISPsystem__Ubuntu-20.04-amd64&period=1&pricelist=5&sok=ok

   Comment

   <platform_address> — URL address of the BILLmanager platform

2. Apply the promo code to the cart:

   <platform_address>?clicked_button=setpromocode&func=basket&promocode=<promo_code>&sok=ok

   Comment

   <platform_address> — URL address of the BILLmanager platform

   <promo_code> — promo code to be applied to the cart

You can create other requests by following the How to generate an API request using the log file instruction in the Guide to ISPsystem software API article of BILLmanager documentation.
