WhatsApp Business API for Transactional & Marketing Messages
Reach customers where they already are. Send order updates, OTPs, and opted-in broadcasts on WhatsApp — with delivery tracking built into the same dashboard as your push and support channels.

notifySphere's WhatsApp Business API integration lets businesses send Meta-approved template messages, two-way conversations, and opted-in broadcast campaigns directly to customers' WhatsApp, with delivery tracking and consent management included — no separate WhatsApp BSP contract required. It works as a WhatsApp messaging API for startups and SaaS teams that want to trigger messages from their own backend.
From Meta account to first message, in three steps
No separate BSP dashboard to log into every time you send a broadcast.
Connect your WhatsApp number
Link your Meta-verified WhatsApp Business number to notifySphere from the dashboard.
Submit message templates
Create and submit templates for order updates, OTPs, or reminders — we track Meta's approval status for you.
Send and track
Trigger templates from your backend or the dashboard, and watch delivery and read receipts in real time.

Do I need my own Meta WhatsApp Business account?
Yes — WhatsApp requires a verified Meta Business account and phone number. notifySphere connects to it and handles template submission, sending, delivery tracking, and consent management on top.
Can I send marketing broadcasts, or only transactional messages?
Both, as long as recipients have opted in per WhatsApp's business messaging policy. notifySphere tracks consent so broadcasts stay compliant.
What happens when a customer replies?
Incoming replies are delivered via webhook and can be routed straight into notifySphere's in-app support queue, so a WhatsApp reply becomes a ticket automatically.
How much does the WhatsApp Business API cost?
Meta charges a per-message rate that depends on the template category and the recipient's country. notifySphere adds a small processing fee per message: ₹0.04 for marketing, ₹0.02 for utility, ₹0.01 for authentication, ₹0.02 for service. Prices exclude GST.
Can I send WhatsApp OTPs through the API?
Yes. OTPs are sent with Meta-approved authentication templates, triggered from your backend like any other template message.
Does the WhatsApp API support webhooks?
Yes. Incoming messages and delivery status updates are delivered to your webhook, so your backend can react to replies, deliveries, and reads in real time.
How long does template approval take?
Template approval is handled by Meta, typically within a business day or two. notifySphere shows you the live approval status so you're not checking Meta's own dashboard separately.
One customer, every channel
Push, WhatsApp, attribution, and support — same customer record, one dashboard.
Real teams, running real campaigns
Switching to notifySphere cut our vendor list from three to one. Push, WhatsApp reminders, and support tickets all live in the same dashboard now — onboarding was faster than we expected.
We needed reliable push delivery without maintaining a separate notification service. notifySphere handled the Firebase setup for us and it's been running without issues since.
