Frequently asked questions
Common questions about connecting Cartesia and Hedy AI.
Connect your Cartesia and Hedy AI accounts once, pick a trigger in one app and an action in the other, then map the fields so data flows automatically between them. [3]
Example: when Cartesia's "Watch Events" fires, WEXTL can "Create a Session Context" in Hedy AI. Cartesia has 2 triggers (including Watch Events and Watch Metric Results); Hedy AI has 20 actions (including Create a Session Context, Create a Topic, and Delete a Session Context). Add filters and transforms between steps when you need them. [1]
Yes — the integration works in both directions. Use each app's triggers to start a workflow and the other app's actions to update it. [2]
No. Cartesia-to-Hedy AI automations are built visually on the canvas. You can optionally add custom JavaScript with Functions when you need advanced logic. [4]
Yes. Trigger-based automations start the moment Cartesia (or Hedy AI) fires a new event — webhook-backed apps run within seconds, and polling-only apps re-check on a schedule you control. [7]
A first automation typically takes 5–10 minutes: connect each app's credential once, drop a trigger + action onto the canvas, map the fields, and turn the workflow on.
You can build your Cartesia + Hedy AI automation on a 3-day trial with every feature unlocked. Cancel anytime. For your protection, a small deposit is charged to your card when your trial starts. It counts toward your first payment and is non-refundable. [8]
