The simplicity to integrate with all 3rd party services like Stripe, Woocommerce and many others. There are also other providers but since I have started using this one, it has been working really well for me in terms of API integration especially when things go wrong. They always respond very quickly and can fix almost anything that you would ask them to do. I am very happy about their support team as they keep updating us regularly on what's going on and how we can improve their product…
