Order Process Before HSBC epdq Payments

[tofayel]

Hi could any one tell me if it possible to process the order before the payments. my site is taking payment using HSBC e-Secure. I have used one contribution for hsbc e-Secure and I had to change my order id to session id which is too long. I had problem with the registering order and everything related with the order id, I have changed the database and all the php code.

 

However, now I am facing another issue that customer buying product, paying on hsbc site and if they aren't returning to our site, the order is not registering and I dont know what they bought. To resolve this problem, I have looked a contribution "order before payment" but I couldnt configure it to hsbc payment module. Have anyone any idea?

 

Is it possible to move payment modules on to checkout success page so that custome can pay later after the order has been register, it sounds straight forward but i didnt look into it and either i dont know if any other issues may arrise, Please advice me

 

Thanks
