Webhook Actions · by Flow Systems · v2.1.2

Very Powerful WordPress AI webhook plugin.

Describe the integration — the built-in AI agent builds it, test-fires it, and hands you the switch. Underneath: async queue, exponential retries, a delivery log you can grep. Zero "fire-and-forget" surprises.

What you can do

Say what you want. Get a working integration.

Type a sentence into Build with AI and the agent proposes a plan, creates the webhook disabled, captures a real payload, maps the fields, and test-fires it before you flip it live. A free Gemini key is enough to run it — or skip the AI and click everything together yourself. Same engine either way.

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.

Anatomy of a Webhook Actions deliveryA WordPress do_action fires the Webhook Actions listener, which builds the payload, applies conditions, and writes to a persistent queue. The queue runner (WP-Cron upgrading to Action Scheduler or system cron) posts to the endpoint: a 2xx is marked delivered and logged, a 5xx or 429 retries with exponential backoff, and a 4xx or 3xx is permanently failed but replayable.

FIG — Anatomy of a delivery
Identity
Every event gets a stable X-Webhook-Id — your receiver can dedupe on it. No double-delivery.
Provenance
Every delivery is logged with its full payload. Filter the log by X-Webhook-Id, event UUID, target URL, status, or date range.
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.
