Emails are filtered into promotions and spam. SMS offers no images, buttons or read receipts. Calls reach customers only when they are free to answer. WhatsApp is already open on your customers’ phones, and they can reply in the same conversation.
Keep the WhatsApp Business app. Add the API.
Many WhatsApp API providers require you to move your number off the WhatsApp Business app. Hello supports coexistence: the number stays active in the app, and Hello adds templates, bulk sending, a team inbox and API access on the same number.
- Same number and profile. No migration, and no change for your customers.
- One conversation history. Replies sent from the phone appear in Hello next to team and API messages.
- Existing data. Import contacts and up to six months of chat history when you connect.

01What is Hello?
Hello is a WhatsApp Business Platform product by Lakshya Pocket Lab. It provides a dashboard for creating templates, sending messages and replying to customers, and a REST API for sending messages from your own systems.
02Can I keep using the WhatsApp Business app on my phone?
Yes. Hello supports WhatsApp coexistence. Connect the number you already use in the WhatsApp Business app and continue using the app, while Hello adds the API, templates and a team inbox on the same number. Replies sent from the phone also appear in Hello, and you can import contacts and recent chat history when you connect.
03Is this the official WhatsApp API?
Yes. Hello is built on Meta’s official WhatsApp Business Platform (Cloud API). Messages are sent from your own business number and follow WhatsApp’s rules for templates, quality ratings and pricing.
04What do I need to get started?
A Meta business account and a phone number for WhatsApp: either a new number, or the one you already use in the WhatsApp Business app. You connect the number from Hello using Meta’s Embedded Signup, then create templates and start sending.
05Why do I need templates?
WhatsApp only allows businesses to start a conversation with a pre-approved template. When a customer messages you, a 24-hour window opens in which you can reply with free-form text, images or documents. Hello supports both and shows which one applies to each conversation.
06How long does template approval take?
WhatsApp usually reviews a template within 24 hours at most. Review times are subject to WhatsApp’s policies. Hello shows the review status and, if a template is rejected, the reason and recommendation provided by WhatsApp.
07Can I send messages from my own software?
Yes. Create an API key in the dashboard and send any message type with a single HTTP request. The documentation includes a complete API reference with an example for each message type.
08Can my whole team use it?
Yes. Invite team members, assign roles, and connect more than one WhatsApp number to the same organization.
09What does it cost?
You pay us only for your Hello plan. WhatsApp’s per-message charges are set by Meta, by message category and the recipient’s country, and Meta bills them directly to your WhatsApp Business Account; Hello does not collect or control them. Contact support@lakshyapocketlab.com for a plan that matches your volume.
Connect your number and send your first WhatsApp message.
