api - Intragram Client ID issue -

i'm having serious trouble instagram , getting latest posts feed json result.

i'm using following link:

https://api.instagram.com/v1/users/client_id/media/recent/?access_token=access_token#

i've registered app on instagram, , put client id on app , put link above. i've registered client id access token it's still doing same thing.

the link says page not found seems right link.

any ideas? take while register client id become valid?

my client id mix of letters , numbers, right?

on note, what's client secret for?

the id in recent media feed user id of user photos wish view (which number), not client id of application. should used access token via oauth process.

if don't know user id can find using ../v1/users/search end point.

the client secret used part of oauth process valid access token.
