# Broadcasts API

A broadcast is a message sent proactively from the bot to a user, without the user sending a request first. It is a great way to reengage your users, for example to remind them about a conversation they didn't finish, or let them know a product they ordered has been shipped.

{% hint style="info" %}
Broadcasts are only available on the PRO plan. More information on the CSML Studio plans: <https://www.csml.dev/studio/pricing>
{% endhint %}

## POST /broadcasts

Send a broadcast on the requested channel (supported channels only) to the requested client. Broadcast requests are queued and usually sent within a few seconds. If a target is unavailable, no error is generated.

### Request example

curl "https://clients.csml.dev/v1/api/broadcasts" \
