WhatsApp Business API Integration

Email gets ignored and SMS gets filtered. WhatsApp gets read — and connecting it to your own system is the part most agencies have never actually done.

Built with proven, modern technology

What is included

Everything you need. Nothing you do not.

Templates approved

Written, submitted and revised until Meta accepts them. This is the part that eats weeks.

Wired to your system

Sent by real events — an order, a payment, a dispatch — not by somebody remembering.

Delivery you can see

Every send logged with its status, so a missing message is a question with an answer.

Honest about cost

Business-initiated messages are billed per conversation. We give you the real number before you commit.

Built properly

Made to last. Not just launched.

Almost every Indian business wants WhatsApp to send order confirmations, receipts, payment reminders and delivery updates automatically. Very few get it working, because the path is genuinely awkward: a WhatsApp Business account, a business service provider, and message templates submitted to Meta and approved before a single message can be sent.

Two-way where useful

Replies reach your team rather than a number nobody watches.

Retries that hold

When the provider is down, messages queue and resend rather than vanishing.

Questions

WhatsApp Business API Integration — FAQ

Is the WhatsApp Business API free?
No. Business-initiated messages are billed per conversation, though utility messages in India are inexpensive. The free WhatsApp Business app is a different product and cannot be automated from your software.
How long does Meta template approval take?
Usually hours, sometimes days, and rejections are common on a first attempt. We write to the rules we have learned the hard way, which is what keeps that number down.
Can it send from our existing number?
Yes, though once a number is on the API it can no longer be used in the ordinary WhatsApp Business app. We talk that through before anything is migrated.
