Set Enable/Disable Stick to the top of the blog using a script

Hey there. I am wanting to use the plugin to “boost” posts. Users would purchase a boost option in WooCommerce, and on completion of the purchase, a script would run that would enable stick to the top of the blog and set a date to disable stick to the top of the blog, based on the boost option they purchased. For example they might purchase a 30 day boost, or a 60 day boost, which would be relayed by the script from Woo to Post Expirator.

Do you have any available API hooks or other suggestions on how I might tackle writing that script?

Thanks!
