But what does that mean?
For example, one client needed a fast and attractive landing site that makes it easy to schedule an appointment with her practice so I created a simple hero-image page featuring a photo of her with an Acuity scheduler integrated right below.
Another example is adding secure payments using Stripe. A designer needed an online portal to set up monthly subscription payments so I used the CheckoutJS tool to accept credit cards there on the site.
Sometimes adding a little bit of live data onto a site can be a real enhancement. I can add weather reports, stock tickers, air quality indicators: if you can get the data on the web through an API, you can put it on your site!
