# Messaging

> Send and receive iMessage, RCS and SMS messages from your Blujay phone numbers.

Every message belongs to a [chat](https://docs.blujay.io/chats/overview.md). You send the first message with `POST /v1/chats` and later ones with `POST /v1/chats/{chat_id}/messages`. Messages from the people you text reach you through [webhooks](https://docs.blujay.io/webhooks/overview.md).

A message is a list of `parts`, sent in order: text, a photo or file, a link, a voice memo or a contact card. Blujay picks iMessage, RCS or SMS for each person unless you choose one.
