# How do I use the RTM API?

****The RTM API lets integrations receive real-time notifications of all events happening in Crisp websites it has access to. This can be used in pair with the REST API to eg. send a message through the REST API, and receive responses from the other party through the RTM API.****

|| 👉 The [RTM API documentation](https://docs.crisp.chat/guides/rtm-api/quickstart/) is available on our Developer Hub.
