Comparing X API’s List lookup endpoints
The v2 List lookup endpoint group will replace the standard v1.1 GET lists/show and GET lists/ownership endpoints. If you have code, apps, or tools that use one of these versions of the List lookup endpoints, and are considering migrating to the newer X API v2 endpoint, then this set of guides is for you.
The following tables compare the standard v1.1 and X API v2 List endpoints:
