# Overview

The 360Messenger API provides the WhatsApp HTTP API for sending and receiving messages, media, groups, channels, contacts, and webhooks.

**Base URL:** `{{base_url}}` (default `https://api.360messenger.com`)

**Authentication :**

* Customer APIs: `Authorization: Bearer {{api_key}}`

* Partner APIs: `Authorization: Bearer {{partner_key}}`

**Rate limits** (approx. per 10s window):

* Basic: 40

* Standard: 70

* Pro: 150

**Plan access:**\
Only **Basic** has endpoint restrictions. Standard and Pro can use the full customer API.

**Basic** can use:

* Send: `POST /v2/sendMessage/`, `POST /v2/sendGroup/`

* Message history (limited): sent status, sent list, pendings *(not the received list)*

* Groups: only `GET /v2/groupChat/getGroupList/`

* Client: most `/v2/client/\\\*` endpoints (getChats, getState, search, …)

* Settings (limited): `getSettings`, country-code helpers

Everything else in this collection (webhook set/scope, Chat, Contact, Channel, full Group/Message actions, received messages list, …) requires a plan above Basic.

**Structure:**

1. Most Used — common flows

2. WhatsApp API v2.0 — full reference (Message, Group, Chat, Client, Contact, Channel, Settings, Webhook)

3. Partner API v2.0 — reseller service lifecycle
