Paypal Future Payment for Mobile.

I need an expert for Paypal Future Payment.

I m going to implement paypal future payment feature on mobile.

I got the authorization code from sdk on mobile.

However whenever I request with authorization code, I got always "invalid_client"

curl '[url removed, login to view]' \

-H "Content-Type: application/x-www-form-urlencoded" \

-H "Authorization: Basic QWZV...==" \

-d 'grant_type=authorization_code&response_type=token&redirect_uri=urn:ietf:wg:oauth:2.0:oob&code=EBYhRW3ncivudQn8UopLp4A28...'

above is curl example.

Who can finish future payment feature?

If you succeed to get token and create a payment, I ill give you further jobs.
