Campaigns

A campaign calls a list of contacts with one agent, within calling hours and a concurrency limit (max_concurrency, up to 100 calls at once, and never more than your workspace's limit on calls at once), and retries people it could not reach.

curl https://evasay.com/api/v1/voice/campaigns \
  -X POST \
  -H "Authorization: Bearer sk-your-key" \

  -d '{
    "name": "Appointment reminders",
    "agent_id": "AGENT_ID",
    "phone_number_id": "PHONE_NUMBER_ID",
    "timezone": "America/New_York",
    "window_start": "09:00",
    "window_end": "18:00",
    "max_concurrency": 2,
    "max_attempts": 2,
    "retry_delay_min": 60,
    "consent_confirmed": true,
    "contacts": [
      { "phone": "+14155550100", "name": "Alex", "appointment": "Tuesday 3 pm" }
    ]
  }'

Contacts may also be CSV text with the phone number in the first column. consent_confirmed: true is required: with it you confirm that everyone on the list agreed to be called, including by an AI voice, and EvaSay keeps that confirmation with the campaign (consent_confirmed_at). The campaign is created as a draft; start it with POST /api/v1/voice/campaigns/{id}/start, and use pause or cancel the same way. The agent must be published before a campaign starts.
