I want to integrate Paytm wallet in an Android application as a payment option, just like in the Uber app. Can anyone help me out? Thanks in advance.
Update
Paytm has added documentation now. http://paywithpaytm.com/developer/paytm_api_doc/
They have support for Android, but they don't have any open documentation.
Use this link to contact them and learn more http://paywithpaytm.com/developer/
