send coins error

[veera]

Hi Team ,
 

We have integrated the Ripple wallet in our server , created address too.

But while withdrawal , we could not proceed further and wee are facing error something like "INVALID PARAMS".

And the URL We used for reference was as follows

https://wiki.ripple.com/Sending_RPC_Commands

And the code we used to send coin was as follows

$result = exec('curl -X POST -d \'{ "method" : "account_info", "params" : [ { "account" : "rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh"} ] }\' http://s1.ripple.com:51234');

 

Here we are waiting for your reply . Is there any other reference as step by step process . Please kindly do the needful.
