Connect

  1. Open Settings → Integrations → Cartesia and click Connect Cartesia.
  2. Paste your Cartesia API key. Create one in the Cartesia dashboard under API Keys. Zelto validates the key against your account before saving it, then stores it encrypted.
  3. Give the connection a label (e.g. Production) so you can tell multiple accounts apart.
You can connect multiple Cartesia accounts to one organization.

What Zelto reads

Zelto reads your Cartesia agents to confirm the key works and to list the agents on your account. The key is account-scoped, so a single key covers every agent.
Agent import and call-log ingestion for Cartesia are on the roadmap. Today the integration connects and validates your account; to bring call data in now, forward calls through Custom & other providers.

​
Connection status & disconnecting

The Cartesia card shows each connected account. The Disconnect action removes the stored API key for that account.
