ElevenLabs Overview#

The ElevenLabs API offers text-to-speech capabilities with realistic voice synthesis. Integrating this API on Pipedream allows you to build automated workflows that convert text content into spoken audio files. You can trigger these conversions from various events, process the text data, send it to the ElevenLabs API, and handle the audio output—all within a serverless environment.

Trigger Configuration#

This component may be configured based on the props defined in the component code. Pipedream automatically prompts for input values in the UI and CLI.

Label	Prop	Type	Description
ElevenLabs	`elevenlabs`	`app`	This component uses the ElevenLabs app.
N/A	`db`	`$.service.db`	This component uses `$.service.db` to maintain state between executions.
Polling interval	`timer`	`$.interface.timer`	Pipedream will poll the ElevenLabs on this schedule

Action Authentication#

Twilio uses API keys for authentication. When you connect your Twilio account, Pipedream securely stores the keys so you can easily authenticate to Twilio APIs in both code and no-code steps.

To connect your Twilio account to Pipedream,

API Key and API Key SID

First, create an API key in Twilio.

There are three types of keys: Main, Standard, and Restricted. You'll need a Main key to interact with certain API endpoints, like /Accounts.
If you don't need to interact with those endpoints, you can use a Standard or Restricted key.

After creating your key, you'll see fields for Sid and Secret. Enter those in the fields below.

Account SID and Auth Token

Visit your Twilio Dashboard. You'll see your Account SID and Auth Token under Account info.
