Steps to build a pinned List lookup request

Step one: Choose the List endpoint collection from Postman Once you have the X API v2 collection loaded in Postman, navigate to the “List” folder, select another folder “Pinned Lists”, and then choose “User’s pinned Lists”.   Step two: Identify and specify the user In order to retrieve a user’s pinned List, you must specify their user ID within the request. The user ID must correspond to the authenticating user’s ID, meaning that you must pass the Access Tokens associated with the user ID when authenticating your request. In this example, you can specify the ID belonging to your own user. You can find your ID in two ways:
  1. Using the users lookup by username endpoint, you can pass a username and receive the id field.
  2. Looking at your Access Token, you will find that the numeric part is your user ID.
In Postman, navigate to the “Params” tab and enter this user ID into the “Value” column of the id parameter.

id2244994945 (user ID)
Step three: Identify and specify which fields you would like to retrieve If you click the “Send” button after step three, you will receive the default List object fields in your response: id and name. If you would like to receive additional fields beyond id and name, you will have to specify those fields in your request with the field and/or expansion parameters. For this exercise, we will request a three additional sets of fields from different objects:
  • The additional follower_count field in the primary List object.
  • The full user object using the expansion parameter.
  • The additional  tweet.created_at field in the associated user object.
In Postman, navigate to the “Params” tab and add the following key:value pair to the “Query Params” table:
KeyValueReturned fields
list.fieldsfollower_countfollower_count
expansionsowner_idincludes.users.id, <br/>includes.users.name, <br/>includes.users.username
user.fieldscreated_atincludes.users.created_at
You should now see a similar URL next to the “Send” button: https://api.x.com/2/users/2244994945/pinned_lists?expansions=owner_id&list.fields=follower_count&user.fields=created_at Step four: Make your request and review your response Once you have everything set up, hit the “Send” button, and you will receive a similar response to the following example response: 
{
  "data": [
    {
      "follower_count": 0,
      "id": "1454155907651158017",
      "name": "test list",
      "owner_id": "2244994945"
    }
  ],
  "includes": {
    "users": [
      {
        "username": "TwitterDev",
        "id": "2244994945",
        "created_at": "2013-12-14T04:35:55.000Z",
        "name": "Twitter Dev"
      }
    ]
  },

    "result_count": 1
  }
