{% hint style="info" %}

Twitter is a free social networking site where users broadcast short posts known as tweets. These tweets can contain text, videos, photos or links. To access Twitter, users need an internet connection or a smartphone to use the app or website, [Twitter.com](http://twitter.com/).
As of 2023, Twitter has **330 million** monthly active users and is one of the top 10 most visited websites.
{% hint style="warning" %}
Twitter has recently made [significant changes](https://twitter.com/TwitterDev/status/1649191520250245121) to its APIs, making it only possible for us to enable new Twitter channel connections with a radical increase in price. As a result, IS-Messenger will no longer allow new Twitter integrations on the platform. Sending and receiving messages on existing Twitter channels connected to IS-Messenger with [Basic tier API](https://developer.twitter.com/en/portal/products/basic) will continue to work as usual. Do [contact us](https://respond.io/contact) should you have any questions about this update.

### FAQ and Troubleshooting
