Similarities

OAuth 1.0a User Context authentication method

The standard endpoint supports OAuth 1.0a User Context, while the new X API v2 users lookup endpoints supports both OAuth 1.0a User Context and App only. Therefore, if you were previously using one of the standard v1.1 users lookup endpoints, you can continue using the same authentication method if you migrate to the X API v2 version.

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

Users per request limits

The standard v1.1 GET users/lookup endpoint allows you to specify 100 users per request. This also goes for the GET /users and GET /users/by endpoints. To specify a full 100 users, you will need to pass the ids (GET /users) parameter or the username (GET /users/by) parameter as a query parameter, and include the list of user IDs/usernames in a comma-separated list.
