[1][2][3] Like other X applications, it interfaces with the X API to allow users to send and receive tweets and view profiles.

[4] On July 4, 2023, X's Support account advised that in 30 days, users must be verified (and subscribed to Premium) to access TweetDeck.

[8] The client uses X's own automatic and invisible URL shortening whereby a link of any length will only use 23 characters of a Tweet's 280-character limit.

For added account security, users signing in with their X username and password can use Twitter's own two-step verification.

This assertion was based on examination of the website code used for TweetDeck, which specifically referenced Twitter Blue.

[13] On July 1, 2023, legacy TweetDeck's functionality was impacted by API changes imposed by Elon Musk to prevent data scraping of the platform for artificial intelligence models, including strict rate limits and the complete removal of a number of API endpoints that were used by the platform without any prior warning.

[14] On July 3, 2023, Twitter subsequently announced that the "preview" version of TweetDeck had exited beta, with all users to be migrated to this new version by the end of the week, but with certain features (such as Teams, which allows other users to be invited to contribute tweets to an account via TweetDeck) not being immediately available.

Many users expressed their anger at this feature removal in the comments on the iOS and Android Market.

[23] At 12:00 PM EDT, Twitter turned off API v1, which effectively shut down the Android, iOS, and AIR versions of TweetDeck.

[24] A cross-site scripting vulnerability in TweetDeck was discovered on June 11, 2014, leading to a self-replicating tweet that affected over 83,000 Twitter users.

[29] Elon Musk stated on July 29, 2023, that TweetDeck will soon been renamed XPro, matching Twitter's rebranding to X.

[40] A year after launching TweetDeck in 2008, Iain Dodsworth received his initial $300,000 seed funding from The Accelerator Group, Howard Lindzon, Taavet Hinrikus, Gerry Campbell, Roger Ehrenberg, betaworks, Brian Pokorny, and Bill Tai.

The company raised a Series A round of funding with many of these same investors, and Ron Conway, Danny Rimer, and the SV Angel group.

[43] This had no bearing on the product or service which was by then run by Twitter, not by TweetDeck Ltd, which was officially struck off the business register by Companies House, and dissolved, for failure to file accounts for 2011.
