The first url will redirect to hosted payment pages card details view.I do not know what should i do with that response.This is the payment integration guidelines for developer.

Answer 1

From the docs you linked to say:
When a webview response is received, the App will need to direct the
customer to the URL given as the start address. The App should monitor
the progress of the webview, and once it reaches the URL provided as
the close address, it should close the web display and continue with
the transaction process.
To complete the transaction, the App must now make a second request to
the gateway. This request includes will trigger the final
authorisation stage of the transaction, and return the authorisation
response. The request must be sent to:
https://secure.innovatepayments.com/gateway/mobile_complete.xml
...
so I would start with that and see what happens
