Got Questions?

Frequently Asked Questions

Everything you need to know about our WhatsApp Business API services.

What is the WhatsApp Business API?

+

The WhatsApp Business API lets businesses send and receive messages at scale. Unlike the free WhatsApp Business app, the API is designed for medium and large companies that need to manage high volumes of customer conversations, integrate with existing systems, and automate responses.

How much does the WhatsApp Business API cost?

+

WhatsApp message cost depends on message category and volume. Example rates are around Rs. 0.20 per authentication message and Rs. 0.80 per marketing message. Final pricing depends on Meta's current rates, message type, and applicable taxes.

How long does it take to set up?

+

Basic API integration can be completed within 1-2 business days. Full deployment including template creation, webhook configuration, and testing typically takes 3-5 business days depending on your technical requirements.

Do I need DLT registration for WhatsApp API?

+

DLT registration is mandatory for sending promotional and transactional SMS in India. While WhatsApp messages are not regulated under DLT in the same way, businesses using WhatsApp for commercial communication should still comply with TRAI guidelines and Meta's business policies.

Can I send messages to people who haven't saved my number?

+

Yes. With the WhatsApp Business API, you can send template messages to any user who has given consent to receive communications. These messages must use pre-approved templates. Free-form messages can only be sent within a 24-hour customer service window.

What types of messages can I send?

+

You can send template messages (for notifications and marketing), free-form replies (during active conversations), and interactive messages with buttons and lists. Media support includes images, videos, documents, and location pins.

Is the WhatsApp Business API secure?

+

Yes. WhatsApp uses end-to-end encryption for all messages. The API itself uses HTTPS for data in transit and supports webhook verification for secure event notifications. We also follow Meta's data protection policies.

Can I integrate with my CRM or ERP system?

+

Yes. The WhatsApp Business API is built on RESTful endpoints, making it compatible with CRMs, ERPs, and custom applications. We support integration through webhooks and API calls.

What is a WhatsApp message template?

+

A message template is a pre-approved message format used for initiating conversations with customers. Templates can include variables for personalization and support text, images, videos, documents, and call-to-action buttons. They must be submitted for Meta approval before use.

Do you provide a WhatsApp chatbot?

+

Yes. We build custom WhatsApp chatbots that handle FAQs, qualify leads, process orders, and escalate to human agents when needed. Our chatbots integrate with your existing business systems for seamless data flow.
