Mobile Recharge API integration within php website

Dear All, We have website which is already have payment gateway as well as wallet system. Now we are going to add Mobile recharge and bill payment system. This is an single API which work all eg. Recharge, Bill, Amount transfer. All document related to this API is provided by service provide and You have to use same document/ code to develop this service eg. [login to view URL] 2nd main work which is included by this project is: 1) Transition history should be provided to user eg. How much amount they added by payment gateway, How much spend for recharge and how much transfer to bank & to other user. API already have facility to transfer amount to bank as well as our website already have facility to transfer amount to other user of website. So you just have to add API of recharge and add transition history of payment within website. eg. Transfer, Payment, Purchase on Store etc. Thank You
