Facebook Domain Verification on a Ticketshop

If you need to do a Facebook Domain Verification, you have two possibilities:

1. If the ticketshop is on your own domain, use the DNS method, by adding the needed value to your DNS
2. If the ticketshop is on *.shop.secutix.com
   1. go to Organization → Initialization → Sales channels → your ticketshop → Points of sales → your point of sale → Theme → Advanced
   2. Create a new entry with key config.head.custom.tags, and put the value of the meta tag in it, like for example:
      <meta name="facebook-domain-verification" content="xxx" />
   3. Wait 10 minutes, to be sure the key is synced to the Ticketshop
   4. Do the verification with Facebook
   5. Remove the meta key from the point of sales
