Frequently asked questions:

What is the WhatsApp Business API?
It’s the enterprise-level interface that allows businesses to integrate WhatsApp messaging at scale, automate conversations, and reach customers programmatically.
How is it different from the WhatsApp Business App?
The App is designed for small businesses and single-device use; the API supports automation, large volumes, multi-agent access and system integrations.
How much does it cost?
Businesses are charged based on the number and type of conversation sessions (business-initiated vs user-initiated) and messages sent.
Can I use my existing WhatsApp number?
A number already registered on WhatsApp may need to be deregistered from the App before it can be used for the Business API.
What are the requirements to get started?
Verification of your business (via Meta/Facebook Business Manager), templates for outbound messages, compliance with policies, and integration with your systems.
Which message formats can I send?
Rich media is supported - images, documents, buttons, quick replies, etc., allowing more interactive communication.
How does Unecast support WhatsApp Business API onboarding?
At Unecast, we handle the full process: business verification, number setup, template creation & approval, API integration, and team training - so you’re live quickly and correctly.
Can Unecast integrate WhatsApp with our existing systems and channels?
