Hey Shawn M.
For reasons only known to Shopify, validating webhooks isn't a primary concern for the layman. You'll have to set the webhooks up via the API, this can also be done using a chrome application called PostMan which is quite easy. Also rather annoyingly, if you create webhooks via the API, there isn't a way to test them without running through the whole process of ordering something since they are hidden from you in the admin section.
