# API Keys

> Use company API keys for the Lead Receive API.

Lead Receive API calls use a company API key in the `X-Company-API-Key` header.

## Getting a key

API keys are provided through approved SimZ onboarding or portal workflows. Public docs intentionally do not expose API key administration endpoints.

## Security guidance

* Store the full key securely when generated.
* Do not expose keys in frontend JavaScript.
* Rotate keys if they are shared with the wrong party.
* Revoke old keys after migration.
