> Migrate add, remove, and manage List member operations from Standard v1.1 lists/members endpoints to the X API v2 manage List members endpoints.

### Manage List members: Standard v1.1 compared to X API v2

If you have been working with the standard v1.1 [POST lists/members/create](https://developer.x.com/en/docs/twitter-api/v1/accounts-and-users/create-manage-lists/api-reference/post-lists-members-create) and [POST lists/members/destroy](https://developer.x.com/en/docs/twitter-api/v1/accounts-and-users/create-manage-lists/api-reference/post-lists-members-destroy) endpoints, the goal of this guide is to help you understand the similarities and differences between the standard v1.1 and X API v2 manage List members endpoints.

* **Similarities**
  * Authentication
* **Differences**
  * Endpoint URLs
  * App and Project requirements
  * HTTP methods
  * Rate limits
  * Request parameters

#### Similarities

**Authentication**

Both endpoint versions support [OAuth 1.0a User Context](https://developer.x.com/content/developer-twitter/resources/fundamentals/authentication). Therefore, if you were previously using one of the standard v1.1 manage List member endpoints, you can continue using the same authentication method if you migrate to the X API v2 version.

#### Differences

**Endpoint URLs**

* Standard v1.1 endpoints:
  * POST [https://api.x.com/1.1/lists/members/create.json](https://api.x.com/1.1/lists/members/create.json)
    (Adds a member to a specified List)
  * POST [https://api.x.com/1.1/lists/members/destroy.json](https://api.x.com/1.1/lists/members/destroy.json)
    (Removes a member from a specified List)
* X API v2 endpoint:
  * POST [https://api.x.com/2/lists/:id/members](https://api.x.com/2/lists/:id/members)
    (Adds a member to a specified List)

  * DELETE [https://api.x.com/2/lists/:id/members/:user\_id](https://api.x.com/2/lists/:id/members/:user_id)
    (Removes a member from a specified List)

**Rate limits**

**App and Project requirements**

The X API v2 endpoints require that you use credentials from a [developer App](/resources/fundamentals/developer-apps) that is associated with a [Project](/resources/fundamentals/developer-apps) when authenticating your requests. All X API v1.1 endpoints can use credentials from Apps or Apps related to a project.

**Request parameters**

The following standard v1.1 request parameters have equivalents in X API v2:

| **Standard v1.1**   | **X API v2**  |
| :------------------ | :------------ |
| list\_id            | id            |
| slug                | No equivalent |
| screen\_name        | No equivalent |
| owner\_screen\_name | No equivalent |
| owner\_id           | No equivalent |
