Taking donations (or “tips”)on your website
You can use Squarespace Commerce to take donations, or allow people to set their own price for something like a “pay what you can” download, or just ask for tips in case people found something helpful.
Donate Button
You can take donations using Squarespace Commerce. Once you have set up Squarespace Commerce, you can insert donation buttons anywhere using a Donate Button block. Here's an example:
Feel free to play around with the above Donate Button - it's not hooked up to take payments, so you can try it without worrying about charges being taken off your card.
“You can also use external donations sites such as JustGiving, by embedding a button onto your site. See the Other Blocks page for more details on using an Embed Block.”
