Automated Voice Calls via ClickSend API

This n8n workflow automates the process of sending text-to-speech voice calls through the ClickSend API. The workflow starts when a user submits a form on a website, providing the recipient’s phone number, the message body, preferred voice gender, and language. Once the form is submitted, it triggers a sequence where the workflow constructs a voice message request, authenticates with the ClickSend API using stored credentials, and then sends the message via an HTTP POST request. This setup is practical for automating notifications, reminders, or critical alerts through automated phone calls, streamlining communication without manual intervention.
