# Twitter Overview
{% hint style="info" %}
To connect Twitter, a [Twitter Developer account](https://developer.twitter.com/en/apply-for-access) is required.
{% endhint %}
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
**Why am I unable to send or receive messages via Twitter API?**
**Twitter API Access Levels**
This is most likely caused by the discontinuation of free Twitter API access. Twitter has announced its new [Twitter API access levels](https://twitter.com/TwitterDev/status/1641222782594990080). With this new update, you will need to [subscribe to the Basic tier](https://developer.twitter.com/en/portal/products/basic) by April 29th, 2023 with the cost of $100 per month to ensure the continuity in using Twitter on our platform. If you encounter any messaging disruption, do [reach out to us here](https://respond.io/contact).
Here’s how you can check the access level of your Twitter developer account:
**Step 1:** Navigate to the [Developer Portal page](https://developer.twitter.com/en/portal/dashboard) on Twitter.
**Step 2:** Click **Products** on the side menu > **Twitter API v2**. Verify if you have the Basic tier access level.
**Does Twitter have a messaging window?**
No, Twitter has no messaging window. Once a Contact has started a chat with you, you can send messages to the Contact anytime.
