# Resume Automation

<span class="badge--post">POST</span> <code class="endpoint-url">/leads/\{id}/automation/resume</code>

Resumes AI automation for a lead's workflow run after it was stopped. The AI will respond to messages again.

Cadence is **not** resumed by default. Set `resume_cadence: true` if you want the automated outreach sequence to restart.

Authenticate every request with the `X-API-Key` header. See [Authentication](/docs/en/api/authentication).
