Thanks for posting and welcome to the Community @Barberandy1 👋.
It's currently not possible to directly integrate a blog template from a 3rd party. However, you can use Square Online's embed code feature to add external content and widget. You'll find more information about this on our Support Centre. Note that this requires an upgrade to Online Plus.
I hope this helps !
