Manage voice agents and initiate calls with Retell.

## Where to configure

Open Zild Admin → Integrations → Connectors, find the provider and use Configure or Edit. Enter the data from this guide, enable the connector for the workflow and save.

## Required fields

These requirements are the data needed by the workflow using the connector. Generic saving may accept empty fields that are only required when an operation runs. Saving does not confirm that the provider accepts the credential.



<table class="api-params"><thead><tr><th>Field</th><th>Workflow requirement</th></tr></thead><tbody><tr><td><code>ApiKey</code></td><td>Provider API key.</td></tr></tbody></table>



## How to obtain credentials

- In the Retell dashboard, open Settings → API Keys.
- Click Add, name the key and allow the Build/Deploy operations needed by the agent and calls.
- Copy the private key into ApiKey. A widget public key does not replace the server credential.

## How it works in Zild

Persona and call services use ApiKey to create, update and invoke Retell agents. The current generic form does not show ApiKey for this type; ask your administrator to configure it if necessary.

## How to verify the configuration

After saving, use the matching workflow (query, agent, call or processing) to verify access. If it fails, check the credential, permissions and selected provider resource. For limited or legacy types, confirm availability with your administrator before use.

When editing, Zild displays protected credentials as asterisks. Preserve the masked value to keep the current credential or paste a new credential to replace it.
