❗️
Our Click-to-Call (C2C) APIs work asynchronously, returning an immediate confirmation like "Call originated successfully" upon initiation.
To track the call lifecycle—such as when the agent answers or the call ends—use webhooks that send real-time event updates to your configured endpoint.

Click to call API lets you dial a customer number by just clicking on the number, without the need of manually dialing it.

The API assists the agents or the users to make calls by entering the number they want to dial and thereafter, choosing the DID number from which they want to make the call. Click to Call is an advanced telephony solution feature which offers various advantages such as:

Hassle-free way to communicate quickly as the caller need not worry about dialing the number in the event of an emergency.
Connects customers to your business and get a company representative on the line with a single click.
Adds to agents’ productivity by saving their time to dial out customer numbers. This cuts manual tasks for Agents and leads to a dramatic improvement in agent productivity.
