Webhook Actions · by Flow Systems · v2.7.4

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.

Inside the plugin

Ten 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.

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.

Changelog

Last three releases.

2.7.4 2026-08-20 Changed: when you have builds but no AI provider connected, Build with AI now opens on your builds with a single "Connect" bar above them, instead of a full-height setup card that pushed everything below the fold. The same provider settings are one click away inside that bar. A site with no builds yet still sees the full setup card.
2.7.3 2026-08-20 Fixedyour past builds no longer disappear when no AI provider is connected. Build with AI used to replace the whole screen with the provider setup card, hiding the build switcher and every transcript along with it — so rotating or removing an API key lost sight of everything you had built with it. The setup card now sits above your build history instead of in place of it, and past builds stay readable. +2 more
2.7.2 2026-08-19 Improvedthe plugin directory listing now spells out what Webhook Actions can connect — which form plugins can act as triggers (Elementor Forms, WPForms, Forminator, Fluent Forms, Gravity Forms, plus built-in Contact Form 7 and IvyForms support) and which destinations you can send to (Slack, Discord, Airtable, Google Sheets, Mailchimp, HubSpot, Salesforce, n8n, Make, Zapier, or any other HTTP endpoint) +2 more
