Describe the integration. The built-in agent builds it, test-fires it, and hands you the switch.

Build with AI
It has already seen the payload and read the API.
A real example of the event — yours, or one of ours for an event your site has never fired — and the destination's current API reference, read before a single field is mapped.
- Payload Library 574 hook payloads from WordPress core, WooCommerce and the major form plugins
- API Docs Library 312 APIs — HubSpot, OpenAI, Slack, Stripe — read on our server, not remembered
- Free credits 55 on every install. No key, no signup, no card.

Inside the plugin
Eleven tabs. Every operation you'll ever do.
The same UI you get in wp-admin after install. Click a tab.
The engine underneath
Queued. Retried. Logged.
Every delivery leaves through a persistent queue, retries on its own schedule, and lands in a log you can grep — and replay.
- Async queue WP-Cron, Action Scheduler or System Cron — whichever the site has, picked up automatically
- Retries & backoff Exponential, linear or fixed, with a limit per webhook
- Delivery log Payload, every attempt, the response body. One click to replay.
- Notifications Slack, email, SMS, PagerDuty and more when a delivery fails, gives up or recovers — rules, quiet times, digests
- External Cron Pro — fires from outside the site, on its own clock, whether anyone visits or not
Anatomy of a delivery FIG — Anatomy of a delivery
Every event has a paper trail.
// log entry 156 — woocommerce_order_status_completed "event_uuid": "37116b42-7a4c-4c6d-8aa7-ea4bc3c13e4d", "trigger_name": "woocommerce_order_status_completed", "request_url": "https://n8n.flowsystems.pl/webhook/126cc22b…", "status": "success", "http_code": 200, "duration_ms": 223, "attempt_history": [ { "attempt": 0, "http_code": 200, "duration_ms": 223 } ], "next_attempt_at": null
Identity
Every delivery names its source: X-Webhook-Id is the config’s UUID, so one endpoint can serve several webhooks.
Provenance
Logged with its full payload. Filter by X-Webhook-Id, event UUID, target URL, status or date.
Recovery
Failed at attempt 1, recovered at attempt 2 — both in the log, with a replay button anyway.
Idempotency
A stable X-Event-Id per event, so receivers deduplicate retries without reading the payload.
