One number,
your whole team.

The WhatsApp Business API is the official way for a company to serve its customers on WhatsApp from its own system, such as a contact center, instead of from a phone. It lets multiple agents and bots chat from the same number, with the conversation connected to your other channels and systems.

Wolkvox, the platform we implement, is a company certified as WhatsApp for Business Technical by Meta, according to its own product page. Wolk-us is its certified partner for the United States and Central America.

One conversation, six points of view

Go step by step and see what happens at the same time for the customer, the bot, the agent, the supervisor, Text Analytics and Agentic Analytics. Each role has its own tab.

Everything it includes

WhatsApp stops being a separate channel and becomes part of the operation: it's handled, automated, measured and supervised with the same tools as voice, chat and email.

Inbox and service

  • Multi-agent inbox, integrated with the rest of Wolkvox
  • Automatic or manual conversation assignment
  • Unified history with the customer's other channels
  • Messages with images, audio, documents and more, within Meta's file restrictions

WhatsApp Voice

Your customers call from the same chat where they already message you, without dialing another number and without losing the conversation. The call reaches your contact center as just another voice interaction.

Frequently asked questions

What is the WhatsApp Business API?
It is WhatsApp's official way for a company to serve its customers from its own system, such as a contact center, instead of from a phone. It lets multiple agents and bots chat from the same number, with the conversation connected to your other channels and systems.
How is it different from the WhatsApp Business app?
The app is designed for a small business that serves customers from a phone. The API connects to a system such as a contact center, so multiple agents, bots and automations can respond from the same number.
What does WhatsApp in Wolkvox include?
It includes a multi-agent inbox built into the platform, automatic or manual conversation assignment, a unified history with the customer's other channels, AI agents that escalate to people, Meta-approved templates, interactive catalogs with buttons and quick replies, segmented bulk messaging and WhatsApp Voice.
Can I receive voice calls on WhatsApp?
Yes. With WhatsApp Business Voice, the customer taps the call icon in the chat or a call button inside a template, and the call reaches your contact center as an inbound voice interaction, with the chat context. It requires your WhatsApp Business API number to be active in Wolkvox and a limit of at least 2,000 business-initiated conversations in 24 hours; after that, the Wolkvox implementation team activates it.
Can I call a customer on WhatsApp?
Yes, but only with the customer's explicit permission. The permission can be temporary (usually up to 7 days) or permanent, and the customer can revoke it at any time. Meta limits permission requests and the number of calls, and requires the number's display name to be approved.
Can a bot handle a conversation and hand it off to a person?
Yes. AI agents can resolve the contact or escalate it to a human agent with the full context of the conversation. You can also require a person to approve before the AI takes an action.
Can I message a customer first on WhatsApp?
When the customer hasn't written to you in the last 24 hours, WhatsApp requires Meta-approved message templates. You can review your use case with us in an Express Assessment.
How do I know which Facebook or Instagram ad brings me conversations?
With Click to WhatsApp, Wolkvox records the source of every conversation that starts from an ad: the URL, the source type, the ad ID and title, the content type and the click ID. Two reports show the detail of each interaction and a consolidated view of chats handled by agents and by bots.
What analytics are included?
Text Analytics measures sentiment and quality in chats, AutoQAi automatically scores 100% of voice and chat interactions, and Agentic Analytics summarizes conversations, calculates metrics such as FCR, CSAT, NPS and AHT, suggests improvements and answers questions in natural language. Supervisors also get real-time monitoring, recordings and reports.
How much does it cost?
It depends on the base license, the channels and the volume of your operation. You can build an estimate with the 2026 Pricing Calculator or book an Express Assessment.
