For templates that include online scheduling, is that something that we can easily integrate?

If you'd like to continue using the Scheduling Blocks included with your template, you'll need to add Squarespace Scheduling to your Squarespace subscription (paid directly to Squarespace). You can do this when you're editing your Scheduling Block.

If you decide to use Squarespace's scheduling platform, there are a lot of Squarespace support articles to help guide you through the process of getting that set up. I'd recommend starting with this one here: https://support.squarespace.com/hc/en-us/articles/360034560592

However, if you'd rather use a different scheduling platform, like Calendly or Simple Practice, these can be easily integrated instead of the included Scheduling Blocks. In this case, refer to the help documentation from your scheduling platform to learn how to integrate with Squarespace.
