Inside the plugin

Nine tabs. Every operation you'll ever do.

Click a tab to see the corresponding admin panel. This is the same UI you'll get in wp-admin after install.

Anatomy of a delivery

Every event has a paper trail.

One row in the log expands to show the full lifecycle: payload, signature, every attempt, the response body. This is what your on-call engineer sees when they get paged.

// 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 event gets a stable X-Webhook-Id — your receiver can dedupe on it. No double-delivery.
Provenance
The triggering hook is recorded with the payload. Filter the log by hook = 'wpcf7_mail_sent'.
Recovery
Failed at attempt 1, recovered at attempt 2. The log shows both — and gives you a ↩ replay button anyway.
Idempotency
Every event carries a stable X-Event-Id (per-event UUID) and X-Webhook-Id (per-config UUID) — receivers deduplicate across retries without inspecting the payload.

Changelog

Last three releases.

1.15.0 2026-06-07 NewCredentials Vault — store reusable authentication secrets (Bearer token, Basic auth, API key, custom header) once, encrypted at rest with AES-256-GCM, and reference them from webhooks via a saved credential instead of pasting a raw Authorization header. Secrets are write-only over the REST API — never returned to any caller, only a masked hint (e.g. Bearer ****1234) — and are decrypted only at dispatch time to build the outgoing header +6 more

1.14.0 2026-06-03 NewActivity History — persistent audit log of every admin and API-token action across webhooks, tokens, settings, logs, queue, schemas, chains, and cron.

Designed to trace automated and AI-assisted changes end-to-end +8 more
