In previous tutorial I have explained how to Get Instagram Access Token Using Client-Side Authentication. Now In this tutorial I will show you how to get self Instagram user ID.
Get self Instagram User ID:
Click Here to receive Instagram Access Token. Now using this token, you can get self basic details like username, profile pic, bio, etc by following URL:
https://api.instagram.com/v1/users/self/?access_token=your_access_token
I have created a function getSelfInstaID() to get self instagram user id using access token.
function getSelfInstaID(){
$token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$url = "https://api.instagram.com/v1/users/self/?access_token=".$token;
   $get = file_get_contents($url);
   $user = json_decode($get);
   if($user->data){
      return $user->data->id;
   }
   return '00000000'; // return this if nothing is found
}
Hope this tutorial will help you to get self instagram user id.
