Select the Insert section and then select More Gadgets.
Find and open the Insert menu in the Google Sites Editor. You will see a list of components you can embed on your site, like Tables, Images, and Links. Find and select the More Gadgets option. This allows you to install customizable tools such as the POWr Recurring Payment to your site.
The Gadget manager will be visible. Select Add Gadget by URL. Then add this exact URL into the field. Choose Add to complete.
Now that you've added your new, editable Recurring Payment Widget to your Google Sites page, you might want to resize the Widget. Using the options in the pop-up, pick a height and width for your plugin. You can decide to create a title, scrollbar or title around your Recurring Payment Widget, but we advise against it. You will have more editing options through the plugin.
Set up POWr Recurring Payment
Visit the live Google Sites website and select the gear icon in the top right corner of your Recurring Payment Widget.
