Telephony via WhatsApp. Voice calls.
Call log and call recording.
Test the calls
Scan the QR code to open the chatbot and try WhatsApp calls.
Add a call button to the interface your agents already use. Messages and calls go through one instance token.
Move from chat to a call in the same conversation. The recording stays in the ticket history alongside the messages.
Calls go over the internet, so there are no roaming charges. Customers don't need to install another app.
Connect a voice bot to WhatsApp calls: it answers the call, handles common questions and hands the conversation over to an agent.
Call customers from a WhatsApp number instead of a landline or mobile line. Calls are started from your system.
The history of incoming and outgoing calls is available via the API. A link to the recording appears after the call ends.
Calls are enabled on your existing instance. No new number, new token or re-authorization needed.
The method works with the regular WhatsApp app. No WhatsApp Business API application required.
Technical support is available around the clock, with response times set in the SLA.
Plans count unique recipients, not minutes. Call duration is not billed.
Create an instance in your console and authorize your WhatsApp number with a QR code.
Enable calls and call recording in the instance user settings.
Call the startCall method, passing a phone number or a lead ID. No other parameters are needed.
Get the call status and the recording link, and save them in your system.
