Start Your Project

Do we need a WhatsApp Business Account before starting?

No. We handle the complete Meta Business verification, WhatsApp Business Account setup, phone number registration, and API access as part of our service — from zero to live.

What's the difference between WhatsApp Business App and WhatsApp Business API?

The app is for small businesses managing chats manually on one device. The API enables automated messaging, bulk sends, chatbots, CRM integrations, and multiple-user access — built for scale.

Can we send promotional/marketing messages?

Yes — through approved marketing message templates sent to opted-in contacts. We handle template creation, Meta approval, and ensure every campaign is fully compliant to protect your number from bans.

How long does Meta verification take?

Meta Business verification typically takes 3–7 business days. WhatsApp number registration is usually approved within 24–48 hours after verification. We manage the entire process and follow up if delays occur.
