Integrating with Stripe can easily be effortlessly done through your Web Portal > Settings Cog > Integrate > Stripe Payment Gateway. An account will first need to be created through Stripe directly.

Once you have selected Stripe Payment Gateway, it will take you to another page where it directs you to 'Begin Integration'. 

When you begin integration, it will connect you to Stripe, where you must enter your details and finish off the process for integration.  After the integration is successful, you can use Stripe for payments.
