# What each part does

> The objects behind the API, and what HueChat uses them for.

The reference is grouped by resource. This page says what each one is for in
HueChat, so you know where to look before you open an endpoint.

## Conversations

A conversation is one thread between a contact and your team on one channel.
It carries a status (open, pending, resolved), an assignee, a team, labels,
priority and custom attributes. The dashboard inbox is a list of these; the
API lets you list, filter, search, assign, resolve and annotate them.

## Messages

Everything said inside a conversation: text, attachments, WhatsApp templates
and interactive replies, from the customer, an agent, an AI agent or an
automation. Sending a message through the API delivers it on the
conversation's channel and shows it in the inbox like any other reply.

## Contacts

The people your team talks to, with phone, email, name, custom attributes,
labels and notes. One contact can have conversations on several channels.
Use the API to create, search, import, export, merge and update them.

## Inboxes

A connected channel: a WhatsApp Business number, an Instagram or Messenger
page, an email address or a website live-chat widget. Inboxes decide where a
conversation comes from and which agents can see it.

## Teams and agents

Agents are the humans in your account; teams group them for assignment and
reporting. The API lists agents and their availability, and manages teams
and membership.

## AI agents

An AI agent is an assistant you build in HueChat to answer customers by
itself. You give it a persona, a language, guardrails, tools and a knowledge
base; publish it to one or more inboxes; and it replies to incoming
conversations in Arabic or English until it hands the thread to a human. The
API creates and updates agents, publishes and pauses them, tests them, reads
their stats, quality and feedback, and rolls back to earlier versions.

## Knowledge

The documents, web pages and text that ground an AI agent's answers. Upload
a file, point at a URL or paste text; HueChat indexes it and the agent cites
it when it replies. Endpoints add, reindex and remove sources.

## Templates and broadcasts

Templates are the pre-approved WhatsApp message formats Meta requires for
business-initiated messages. Broadcasts send a template to a list of
contacts, from a CSV or a saved audience, with scheduling, pause and resume,
and delivery reports.

## Workflows and chat menus

Workflows are automation flows built from triggers and steps: route, tag,
reply, wait, hand off. Chat menus are the numbered or button-driven menus a
customer sees at the start of a conversation. Both can be created, published
and toggled through the API.

## Webhooks

Two kinds: signed outbound webhooks (recommended) that push events such as
`message.created` to your server, and the older account webhooks used by the
dashboard. See [Webhooks](/webhooks).

## API keys

Scoped `hc_` keys with their own scopes, rate limit, IP allowlist and expiry,
plus rotation and a usage log. See [Scoped API keys](/api-keys).
