To accept payments via Stripe, you'll need a Stripe account to get started.
Click on the School Icon.
Navigate to the Settings page, found at the bottom of the sidebar. Select the Payments page.
From here, press the Connect button next to Stripe. You'll be asked to login to your Stripe account and authorise the connection.
When this is complete, you'll be taken back to the payments page and you'll now be able to accept payments through Stripe.
