According to Engadget, changes to the API have affected apps like Jetpack Social, Flipboard, Echobox, and Social Bearing, as well as Post News and Substack login features. The new free API offers only 1,500 requests per month and access to Twitter logins per app.
Twitter’s decision to shut down access to the old API also affected developers willing to pay for the new API. Thereupon, the developers of Echobox stated on their blog that they did not receive a response from Twitter’s corporate sales department and that their access to the API was terminated without warning.
