How to use Magento Filters

[Gopiandh]

Hi,
I am trying to integrate the MAGENTO into salesforce. My requirement is to schedule classes based on time filter to get the data of MAGENTO into salesforce. I fallow the sfdc-oauth-playground code to authenticate. I am getting error while using the filters of MAGENTO in the sfdc-oauth-playground.

When i am trying to use 'GET' method response from sfdc-oauth-playground by using this MAGENTO filter which is something looks like "http://hostname/rest/products?filter[1][attribute]=created_at&filter[1][gt]="2015-10-05 11:23:15" " i am getting the error like "{"messages":{"error":[{"code":401,"message":"oauth_problem=internal_error&message=Invalid URI supplied"}]}}". The same error response is persisting even i use the date in an encoded form as well. kindly help me out where i was doing wrong. Please tell me how to use the filters without which my task could not be accomplished.

Thanks.
