Send OTPs, automate customer support, run broadcast campaigns, and build conversational commerce — all through one API. Sparrow SMS is an official Meta-approved WhatsApp Business Solution Provider.
Meta's official interface for businesses that need to reach customers on WhatsApp at scale — legally, reliably, and with full automation.
The WhatsApp Business API is not an app you download. It is a programmable interface that connects to your existing systems — your CRM, website, app, or back-end — and lets you send, receive, and automate WhatsApp messages from your own infrastructure.
It is the only way to legally send bulk messages, deploy chatbots, integrate WhatsApp with a CRM, or manage conversations across a team. Accessing it requires an official Meta Business Solution Provider (BSP). Sparrow SMS is an official BSP.

Sparrow SMS guides submission — first-time approvalYour dedicated number is registered as a WhatsApp Business Account (WABA). Eligible accounts can apply for the green tick verification badge.
Every outbound message requires a Meta-approved template. Sparrow SMS helps you write, format, and submit templates for every use case. Approvals take 24–72 hours.

Sandbox access available for testingStart at 1,000 conversations/day. Limits scale automatically to 10,000, 100,000, and beyond as your account quality builds with Meta.
Meta divides all WhatsApp Business API messages into four categories. Understanding them is essential for compliance and cost control.
One-time passwords, 2FA codes, account verification, secure login flows. Strictly for security — no marketing content allowed.
Transactional messages triggered by a user action. Order confirmations, shipping updates, appointment reminders, payment receipts.
Promotional campaigns, product launches, seasonal offers, re-engagement. Highest cost — reserve for high-ROI campaigns.
When a customer messages you first, a 24-hour free conversation window opens. Reply freely — no template required. Closes after 24 hours.
Build chatbots visually — no developer needed. Or integrate Dialogflow / OpenAI for AI-powered conversation flows. Handles repetitive queries 24/7.
Unlimited agents, one business number. Assign conversations, add internal notes, create routing rules by department, track SLAs.
Send to millions simultaneously. Segment by any attribute, personalise with dynamic variables, schedule for optimal delivery times.
Rich interactive forms, surveys, and appointment schedulers — entirely inside WhatsApp. No external links. No app downloads.
Meta ad clicks land directly in a WhatsApp conversation. 72-hour free messaging window opens on every ad conversation.
