We use Stripe.com as our payment processor. They handle all aspects of security, payouts, etc.
You will need a Stripe account, but if you don't have one, don't worry, it's easy and free to sign up!
In your Ticket Space dashboard, navigate to My Ticket Space > Settings
Next, click on Payment Gateways, and scroll to the bottom.
At the bottom, if you have never connected you will see "Connect with Stripe". Click on this, and it will redirect you to sign into your stripe account, OR it will also allow you to create an account if you do not have one.
Please choose the correct currency as well, and set the Force SSL (Live Site)!
That is it! Your My Ticket Space is now connected to your Stripe account, and you can immediately start receiving payments from your customers.
