Terms of Service is an add-on for the WordPress Stripe Checkout plugin that can be used to show a terms of service agreement checkbox on the Stripe payment page. When this feature is enabled, buyers are required to check the terms of service checkbox before they can pay for a product.

Terms of Service URL Configuration
Before you can show a terms of service checkbox on the Stripe payment page, you need to provide a URL to Stripe that will show the terms of service. You need to enter this URL in the Terms of service field which you can find under Settings > Public details section of your Stripe account dashboard.

How to Show Terms of Service Checkbox (Option 1)
You can enable terms of service checkbox in the product interface of the Stripe Checkout plugin.

Once you have created a new product or edited an existing one with this option enabled, add the shortcode for it to a post/page.
[wp_stripe_checkout id="1"]
Replace the value of id with your product ID.
How to Show Terms of Service Checkbox (Option 2)
If you are using the “wp_stripe_checkout_session” shortcode in the Stripe Checkout plugin, you can change it to the following to enable terms of service checkbox.
[wp_stripe_checkout_session name="My Product" price="2.99" terms_of_service="required"]
