Parabola as it is defined on its website: Parabola makes it easy to automate your manual, repetitive data tasks.
That being said, Parabola helps to extract and send data to and from the apps and programs you use most.
This can be very beneficial if you run an ecommerce Website on Squarespace. It will definitely allow you to organize your orders.
The following picture shows the process:
You can connect your API directly. (API coolest definition by the way)
You can also connect your Squarespace account. This is still in Beta. I do not recommend it that much.
Parabola also has a tutorial on how to analyze your Squarespace orders.
Keep in mind for being able to do this you need to have the Advanced Commerce Plan on Squarespace, which allows you to have Commerce APIs
