Stop all sending for a campaign right away.

Mailshake API: https://cotlet.dev/docs/api/mailshake.md

`POST https://cotlet.dev/api/v1/mailshake/campaigns/{campaign_id}/pause`

Access: write.

Pauses a campaign. A batch of emails already being sent is not stopped. It reaches no one and resume_campaign undoes it, so it does not wait for your OK. Recipients keep their place in the sequence.

## Parameters

|---|---|---|---|
| `campaign_id` | integer | yes | Campaign ID from list_campaigns. |

result = client.call("mailshake", "pause_campaign", {"campaign_id":1})
```

**Node.js**

## 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.
