Hey there harishchand,
Hope you’re well today 🙂
Unfortunately adding another payment gateway is more toward custom development rather then support so even with premium support the best we could do is add that to our features and feedback section in the forum so other members can vote on adding that, then if it proves to be popular we would consider adding such gateway to Membership 2.
As much as we would like to add all features our members are asking for we can’t so if you need to customize this you’d have to hire a developer to assist you further.
Have a nice day.
Best regards,
Bojan
