Standard v1.1 compared to Twitter API v2

If you have been working with the standard v1.1 followers/ids, v1.1 followers/list, v1.1 friends/ids, or v1.1 friends/list endpoints, the goal of this guide is to help you understand the similarities and differences between the standard and Twitter API v2 follows lookup endpoints.

  • Similarities
    • Authentication
    • Users per request limits
  • Differences
    • Users per request limits
    • Endpoint URLs
    • App and Project requirements
    • Response data formats
    • Request parameters




Both the standard v1.1 and Twitter API v2 follows lookup endpoints accept either OAuth 1.0a User Context and OAuth 2.0 Bearer Token. Therefore, if you were previously using one of the standard v1.1 follows lookup endpoints, you can continue using the same authentication method if you migrate to the Twitter API v2 version. 

Depending on your authentication library/package of choice, Bearer Token authentication is probably the easiest way to get started and can be set with a simple request header. To learn how to generate a Bearer Token, see this OAuth 2.0 Bearer Token guide

Users per request limits

The standard v1.1 endpoints allows you to return up to 5000 users per request. The new v2 endpoints allows you to return up to 1000 users per request. To return a full 1000 users, you will need to pass max_results=1000 as a query parameter; you can then pass the next_token returned in the response payload to the pagination_token query parameter in your next request.



Endpoint URLs

  • Standard v1.1 endpoints:
      (list of user IDs who are followers of the specified user)
      (list of users who are followers of the specified user)
      (list of user IDs the specified user is following)
      (list of users the specified user is following)
  • Twitter API v2 endpoint:
      (list of users who are followers of the the specified user ID)
      (list of users the specified user ID is following)

App and Project requirements

The Twitter API v2 endpoints require that you use credentials from a developer App that is associated to a Project when authenticating your requests. All Twitter API v1.1 endpoints can use credentials from standalone Apps or Apps associated with a project.

Response data format

One of the biggest differences between standard v1.1 and Twitter API v2 endpoint versions is how you select which fields return in your payload.

For the standard endpoints, you receive many of the response fields by default, and then have the option to use parameters to identify which fields or sets of fields should return in the payload.

The Twitter API v2 version only delivers the user id , name, and username fields by default. To request any additional fields or objects, you wil need to use the fields and expansions parameters. Any user fields that you request from this endpoint will return in the primary user object. Any expanded Tweet object and fields will return in an includes object within your response. You can then match any expanded objects back to the user object by matching the IDs located in both the user and the expanded Tweet object. 

We encourage you to read more about these new parameters in their respective guides, or by reading our guide on how to use fields and expansions

We have also put together a data format migration guide which can help you map standard v1.1 fields to the newer v2 fields. This guide will also provide you the specific expansion and field parameter that you will need to pass with your v2 request to return specific fields. 

In addition to the changes in how you request certain fields, Twitter API v2 is also introducing new JSON designs for the objects returned by the APIs, including Tweet and user objects.

  • At the JSON root level, the standard endpoints return Tweet objects in a statuses array, while Twitter API v2 returns a data array. 
  • Instead of referring to Retweeted and Quoted "statuses", Twitter API v2 JSON refers to Retweeted and Quoted Tweets. Many legacy and deprecated fields, such as contributors and user.translator_type are being removed. 
  • Instead of using both favorites (in Tweet object) and favourites (in user object), Twitter API v2 uses the term like
  • Twitter is adopting the convention that JSON values with no value (for example, null) are not written to the payload. Tweet and user attributes are only included if they have a non-null values. 

We also introduced a new set of fields to the Tweet object including the following:

  • conversation_id field
  • Two new annotations fields, including context and entities
  • Several new metrics fields 
  • A new reply_setting field, which shows you who can reply to a given Tweet


Request parameters

The following standard v1.1 request parameters accepted two request query parameters (user_id or screen_name). The Twitter API v2 only accepts the numerical user ID, and it must be passed as part of the endpoint path.
