Reach customers instantly with the WhatsApp Business API.
Send updates, offers and support messages on the app your customers use every day, with a verified business profile, team inbox and automation.
Official WhatsApp Business API for growing businesses
Most of your customers check WhatsApp many times a day. The WhatsApp Business API lets your business message them at scale with a verified profile, multiple team members and automation, which the basic WhatsApp Business app can't do.
Zap-Pass handles the complete setup: Facebook Business verification, API activation, message template approval and onboarding. Once live, you can send broadcast campaigns to opted-in customers, reply from a shared team inbox, and use chatbots to answer common questions and collect lead details around the clock. Order updates, payment reminders and appointment confirmations can be sent automatically.
The API integrates with your CRM, website and forms, and works with Click-to-WhatsApp ads so people who tap your ad land straight in a conversation with your team. You get delivery and read reports for every campaign, so you can see what's working.

WhatsApp Business API FAQs
Answers to common questions about our whatsapp business api services.
What is the WhatsApp Business API?
It is Meta's official solution for medium and large businesses to send messages at scale, use multiple agents and connect WhatsApp with other software.
How is it different from the WhatsApp Business app?
The app works on one or two devices for small volumes. The API supports bulk messaging, many agents, chatbots and integrations.
How long does setup take?
Setup usually takes two to seven working days, depending on Facebook Business verification.
Can I get the green tick?
We help you apply for the verified badge. Approval is decided by Meta based on your brand's public presence.
What are WhatsApp API message charges?
Meta charges per conversation, with different rates for marketing, utility and service messages. We'll explain current pricing and help you plan your budget during the consultation.
Can I use my existing WhatsApp number?
Yes, in most cases. The number must be removed from the regular WhatsApp or WhatsApp Business app before it can be moved to the API.
Can I send bulk messages to anyone?
Messages can only be sent to customers who have opted in, using templates approved by Meta. This keeps your number in good standing and avoids blocks.
