# Overview

Practical flows: send (private + group), groups, channel, message history, webhook & event scope.

**Auth:** Bearer `{{api_key}}` (inherited).

**Plan note:** Only Basic is restricted. It can send messages and use getGroupList, sent/pending lists, most Client APIs, and getSettings. Webhook, event-scope, Channel, and many Message/Group/Chat/Contact actions need a plan above Basic. See the collection description for the Basic list.
