If you already have your ElevenLab secrets, you can skip ahead to “Part 2 - The Base44 side” setup
1

Get your ElevenLabs API key and Voice ID

  1. Sign in to ElevenLabs and go to: Profile → API Keys → Create key.
    ElevenLabs Settings on the API Keys tab with an API Keys Missing notice and the Create API Key button

    Creating an ElevenLabs API key

  2. Copy and save the key somewhere secure, but also keep it handy as you’ll need to paste it into Base44 later.
  3. While creating the key, turn on Restrict Key and choose which features this key can use:
    Create API Key dialog with Restrict Key turned on and Text to Speech set to Has access

    Restricting the key to Text to Speech

    At a minimum, enable Text to Speech. Keep all other features set to “No access” unless you specifically plan to use them (e.g., Speech to Speech, Speech to Text, Sound Effects, Dubbing, etc.).
    Set a Credit Limit for this key and scope it to a Project if you use projects.

Choose a voice ID

ElevenLabs Voices library on the Explore tab with trending voices and a Create or Clone a Voice button

Choosing a voice in the ElevenLabs library

You can pick any voice available to your account whether it’s stock/public voices, your own custom or cloned voices, or shared/community voices.
Tip: Add the voice to My Voices, then copy its Voice ID (for example: Bella EXAVITQu4vr4xnSDxMaL). If you want app users to switch voices, store multiple Voice IDs and display them in a dropdown.
Important: Each API request uses your ElevenLabs credits. All billing happens directly with ElevenLabs, not through Base44.

    Example: Personal trainer app

Show one exercise at a time with work/rest timers.**App prompt to conect ElevenLabs: **Connect this app to ElevenLabs Text-to-Speech as an Instant integration. Ask me for ELEVENLABS_API_KEY and VOICE_ID and save them as Secrets. Create a backend function that calls ElevenLabs and returns MP3 as a Base44 data URL.
  3. In the AI chat, click Set secrets.
