What is the WhatsApp Business API?

The WhatsApp Business API (Meta Cloud API) lets businesses send and receive WhatsApp messages programmatically at scale — notifications, marketing and support. Different from the free WhatsApp Business app.

How do I get WhatsApp Business API access?

You need a Meta Business Manager account, a verified phone number, and Cloud API access. ClientFlow4U guides you through Meta Embedded Signup or manual setup during onboarding.

How much does WhatsApp Business API cost?

Meta charges per 24-hour conversation, varying by country and category. ClientFlow4U adds no markup.

Q: Cloud API vs On-Premise?

Cloud API is Meta-hosted — minutes to set up, no servers. On-Premise is self-hosted and being phased out. ClientFlow4U uses Cloud API.

Connect your Meta Cloud API number once. Send templates, launch campaigns and reply to customers in minutes — no servers, no code, no hidden markup.
