Odysys does not yet have a shopping cart integrated for selling gift certificates, but don't let that stop you!
If you want to sell gift certificates on your website, complete with an online checkout page:
You will need to set up an account with an online store like PayPal, Shopify or other third party vendor to sell gift certificates. Once that is in place we can use the code from that third-party vendor and embed the button or the shopping cart or place a link on your site. Once that is in place, your visitors can click a button to purchase a gift certificate online via your 3rd party shopping cart.
These are just two examples - but there are other vendors out there as well.
If you just want to take orders for gift cards over the phone or in person etc and send out a certificate via mail:
If you are using the Odysys booking engine, you already have an account with payment processor stripe.com. You can simply login to Stripe and create any charge you want with a customer's credit card.
