I just checked the API documentation. It seems that all the requests are through HTTP POST, including Get Status and Get Link, wonder how can that be considered as RESTful?
Alternatively, if they need a body for their "GET" requests, that might be why it's a POST?

Cashfree looks promising and something really needed in India especially the bank transfer API. Good luck to the team.
Documentation of Bank transfer products (Payout and NEFT re-conciliation) is not public yet. We send it to our merchants during their on-boarding. We understand that it makes evaluation by new/prospective customers at bit harder and thus, are in-process of revamping our doc site to include documentation of all the products we support.
Do drop us a note at care@gocashfree.com. We will share it with you.
