Elevenlabs Text-to-Speech API with n8n Webhook

Overview

This n8n workflow creates a custom API endpoint that allows you to generate text-to-speech audio using Elevenlabs.io. It's designed to be triggered by an incoming webhook POST request. The workflow first checks if the necessary parameters (voice_id and text) are present in the request. If they are, it proceeds to call the Elevenlabs API to generate the speech and then responds with the binary audio data. If the parameters are missing, it returns an error. This is particularly useful for integrating text-to-speech capabilities into other applications or automating content creation pipelines.
