Wordpress / Woocomerce Webhook Custom Logic

General information for the website: We sell clothing online Kind of development: Customization of existing website Num. of web pages/modules: 1 Description of requirements/features: Hi, I currently send orders to suppliers from Woocomerce once payment has been received using the API and webhooks. At the moment I can either configure it to send to both suppliers or 1, what I would like to do is add a logical if statement to determine which web hook should be triggered based on the order location, i.e if the order is from the UK fire of the UK supplier webhook, if the order is from Germany fire the Germany supplier webhook. I've done a fair amount of scripting in the past but PHP is not one of my strong points. I believe this is achieved using the woocommerce_webhook_topics function but I'm not sure where the logic should be implemented. Thanks Extra notes:
