Manage phone calls from your systems with a Voice API

Create the ideal communication solution for your business by automating outbound calls with the Voice API.

Voice API
A voice API to simplify your calls

With a voice API, a software interface, you can receive and make calls in an automated way. This API is the link between your systems and our platform. Everything is integrated directly on your premises. Nothing could be simpler or more efficient!

Voice API
Why a Voice API
for your business?

Deliver a better customer experience and engage your customers with a programmable voice API.
Plus, you only pay for what you use.

Maintain customer relationships

Create personalised and interactive campaigns using placeholders or recordings and communicate clearly with customers in their own language.

Use our Voice API to call customers in case of non-payment or optimize the timing of external calls to contact candidates in the context of a job search.

Engage with your users

Record and capture important data to improve your campaigns and use our programmable API to turn phone calls into effective campaigns.

With the Voice API, take advantage of cross-channel communication (transfer to an agent, SMS, email) and review the success of your campaign with real-time statistics.
