Kommo API: https://cotlet.dev/docs/api/kommo.md

`POST https://cotlet.dev/api/v1/kommo/chats/{chat_id}/messages`

Access: write. Confirm: waits for the user's OK before it runs.

Sends the text in the same chat and channel, under your name, and returns the message_id. It reaches the client at once and Cotlet cannot recall it. Voice messages, files and templates are not sent. What the channel allows depends on the channel Kommo has connected. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `chat_id` | string | yes | Chat ID from list_conversations or list_incoming_leads. |
| `text` | string | yes | Message text. Plain text only. |

## Request

  -H "Content-Type: application/json" \
  -d '{"text":"Hi Ana, the yoga studio package is 750 for 4 sessions a month. Want me to book the first one this week?"}'

```

## For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests.

One call creates the account and sends the access request; we email the user when access is granted.
