Developer/coder help needed with rental automations

I have a rental company that uses Wordpress, Woocommerce and SmartThings and with the new switch my end user code is no longer working. Before renters would rent through my website which employed Woocommerce and SmartThings handled all the locks on my sites. This is no longer working. I’m not a coder by trade and would love to hire someone that is familiar with all three or get their guidance.
