Future Ticketing provides a script which enables any site to host a ticketing page but the website needs to be enabled first.
Once this has been done and saved then the new website will appear in the dropdown list which new events can show their tickets on. If you already have events and products (tickets) set up then you will need to go back and add the new site to places where the event is available.
Now you have to include the Future Ticketing script on the webpage that you added in the section above.
Depending on what web creation software you are using you will need access to the page in question and the ability to include a script. In many editors this is done through the use of a Custom HTML block.
For example, in WordPress, you would add a new block, then choose from Custom HTML from the options.
Inside that block add the following:
<!--Future Ticketing API - START-->
<script type="text/javascript" src="https://embed.futureticketing.ie/ft5f7da2ca13858"></script>
<script type="text/javascript">var FTicket = FT({});</script>
<!--Future Ticketing API - END-->
Then save the page and load it in a browser. Hopefully you should now see the Future Ticketing shop in the place where that custom HTML was placed.
