When I started my career, one thing that i never wanna do is to integrate payment. I felt it was hard and requires more responsibility.
I started working for a website design company & they have there product which was deployed across the world, it was my worst nightmare. I had approximately 50 payment provider which I had to integrate. Once I started working on it, it was a piece of cake. Now I am very comfortable with integrating any payment processor to any website.
Only then I realized, you would never know how it is, how it's gonna be & how it's end, until you try it.
