Which APIs to use for building a payment gateway

[iamgroot]

Hello,

I am working on building a payment gateway which would allow developers to integrate my SDKs into their application and accept payments. 

Which APIs would you suggest  me to use. Also, it would be helpful if there was a link which explained how I can implement this from user entering his card details to charging his card.
