Response

Returns the created follow-up object. 
curl -X POST "https://app.replyify.ai/api/follow-ups" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contact_id": "contact_abc123",
    "client_id": "client_xyz789",
    "due_at": "2025-02-01T10:00:00Z",
    "notes": "Follow up on pricing discussion from last week",
    "action": "follow_up_message"
  }'
The due_at must be in the future. Creating follow-ups with past dates returns a 400 error.
If no draft_message is provided, AI will automatically generate the message before the scheduled send time. This consumes 1 AI credit for generation + 1 for sending = 2 credits total.
