Easily integrate one-click calling into your customers’ online shopping experience.

Click-to-call allows users to initiate a voice conversation with your customer service agents simply by clicking a button. This can help resolve issues and answer questions with minimal interruption to the user’s journey.

The easy way for businesses to add a click-to-call system is through an API like Deutsche Telekom’s Voice API. It’s the fastest, easiest way to allow customers to connect with a company representative by phone while they’re browsing a website or in an app.

Adding click-to-call to your website with our Voice API is quick, easy, and can be accomplished in a matter of minutes.

With just one click, the user initiates a voice call directly from their browser or app. A button, image, or text on the site or app lets the user enter a phone number and request an immediate call back.

While the call is being established, contextual information about the customer - such as their name, the page they’re currently visiting, and any other relevant information the API can access - is passed to the dedicated expert on the call. The customer doesn’t have to actually enter this information, as the service knows it automatically. This process allows users to receive highly personalized customer service, with the easy click of a button.
