# What is WhatsApp Business API?

The WhatsApp Business API lets companies send and receive WhatsApp messages at scale through approved providers, using pre-approved templates and customer opt-in.

It is commonly used right after a call: sending a summary, a payment link, a location or a brochure to the person you just spoke to.

Business-initiated messages generally need an approved template and the customer's opt-in; free-form replies are allowed within a limited window after the customer messages you.

At Vyora: Vyora integrates with WhatsApp providers such as AiSensy, Interakt and WATI.

## Common questions

Why combine calls with WhatsApp?

A call opens the conversation and a message gives the person something to act on afterwards, such as a link or details.
