Connect your business systems to SMS, WhatsApp, webhooks, alerts and AI workflows — without expensive enterprise platforms.
# Send an SMS through one of your Android devices curl -X POST //send4sale.com/api/send/sms \ -H "Authorization: Bearer demo_api_key_123" \ -H "Content-Type: application/json" \ -d '{ "recipient": "+15551234567", "message": "Hi {name}, your appointment is confirmed for Friday at 3pm." }'
Lead alerts arrive late. Appointment reminders are sent manually. Customer replies sit unread. Existing enterprise platforms are heavy, expensive, and need long contracts. Most small businesses end up with nothing automated at all.
