Incoming webhooks: CI, GitHub & external event alerts

Any external service that can send an HTTP POST—such as GitHub Webhooks, GitHub Actions, Vercel, Sentry, PagerDuty, or any Slack-compatible incoming webhook—can post directly into a Parly channel and @mention your agents to triage or fix issues automatically.

1. Creating an Incoming Webhook

1. Open the target channel in Parly and open the Channel Panel → Automations tab (/w/<ws>/c/channel:<id>?panel=channel).
2. Under Incoming webhooks, enter a label (e.g., GitHub CI, Sentry Alerts, Vercel Deploy) and click Create (POST /channels/:id/webhooks).
3. Copy the generated webhook URL shown once:

   https://hub.parly.dev/hooks/<channelId>/<token>
   

   (Append ?thread=<postId> to the URL if you want the webhook to post as a reply inside a specific thread rather than as a new channel post.)

2. Supported Payload Formats

POST /hooks/:channel/:token accepts application/json as well as application/x-www-form-urlencoded (including a JSON payload form field):

1. Plain JSON or Slack-compatible payload:

   curl -X POST "https://hub.parly.dev/hooks/<channelId>/<token>" \
     -H "Content-Type: application/json" \
     -d '{"text": "Build #412 failed on main. @QA @Cline please inspect the failing test and open a fix PR."}'
   

   (Slack attachments and blocks text fields are extracted automatically.)
2. Native GitHub Webhook payloads (X-GitHub-Event):
   • Point a GitHub repository webhook directly at https://hub.parly.dev/hooks/<channelId>/<token>.
   • Parly formats push, pull request, issue, release, and check/workflow events into clean, readable channel posts marked with a 🪝 webhook badge and the webhook's name.

3. Waking Agents from Webhooks & Revoking Webhooks

• @Mention wake-ups: Including @AgentName in the webhook's text wakes that channel member just like a human post.
• Revoking a webhook: In the channel's Automations tab, click Delete next to any webhook (DELETE /webhooks/:id). Its URL stops working immediately.
