# Real-Time Apps Deprecation Notice

We’re announcing the **end of support for real-time apps** that were built using the **JSON-RPC v1 API**.

<Callout icon="❗️" theme="error">
  ### 📅 End of Life: January 1, 2027

  Since the JSON-RPC v1 API is being deprecated and will be permanently turned off on **01/01/2027**, real-time apps that rely on it will also stop functioning after this date.
</Callout>

Real-time apps were typically hosted on customer servers and relied on complex code and flows tied to the v1 infrastructure. With v1 being retired, those legacy real-time integrations can no longer be supported.

***

## 🚀 Migrate to Callr Actions

We encourage all customers using real-time apps to migrate to **<Glossary>Callr Actions</Glossary>**, our new, more powerful and flexible framework for designing communication workflows. Callr Actions lets you:

* Design call and message logic using a declarative, YAML-based framework inspired by modern automation tools.
* Build inbound, outbound, and API-triggered flows without managing servers.
* Connect calls and SMS to your backend in real time using actions like `fetch@v2`.
* Integrate dynamic logic such as data lookups, conditional branches, and real-time personalization without telephony servers.
* Leverage advanced features like multi-channel AI agents and extract insights with built-in actions.

## 📢 Reminder Notifications

Customers still using real-time apps tied to JSON-RPC v1 will receive **automated reminder emails once per month** until their migration is completed.

***

## ⚠️ What You Should Do Next

* Review your existing real-time app usage.
* Plan your migration to <Glossary>Callr Actions</Glossary>.
* Use the documentation and templates in the Callr Console to rebuild your flows.
* Complete migration well before **January 1, 2027** to avoid service interruption.

If you need help, contact our support team. We’re here to assist with your transition to Callr Actions.
