Code Engine – PHP Snippets, AI Functions & Automation for WordPress vs Webhook Actions – build automations and integrations with AI help

Code Engine is a snippets manager that doesn’t stop at snippets. Yes, it runs your PHP and JavaScript exactly where and when you want: frontend, backend, on a schedule, or inside your content. But its real magic is what happens after you write a function: the same little piece of code instantly becomes a tool your AI chatbots can call, a step you can drag into a visual workflow, and an endpoint the outside world can trigger. One function, three superpowers. Most “code snippets” plugins stop at a textarea and a toggle. Code Engine treats your functions as first-class building blocks for the whole Meow Apps ecosystem, and for anything that can speak REST. Think out of the box, let your creativity flow, because the possibilities really are endless! ✨ For more, check the official website and come say hi on the Discord. Quick Intro Hello! ☀️ I built Code Engine because I was tired of pasting mystery snippets into functions.php and praying. I wanted a place where small bits of code are organized, safe, AI-assisted, and reusable everywhere. Here’s the idea. You write a function (or let the AI write it for you from a plain-English description). That function immediately shows up in three places: AI Engine: your chatbots and MCP clients (Claude, ChatGPT, Claude Code) can call it as a tool, with real arguments. Ask “how many orders shipped today?” and your chatbot runs your function to answer. Workflow Engine: your function appears in the step picker as its very own block. Drag it onto the canvas, wire it between an AI step and a Slack step, done. No glue code. REST / External tools: give it a secure endpoint and a token, then trigger it from Make.com, n8n, Zapier, a cron job, or a webhook. You never wrote an “integration.” You just wrote a function. Code Engine did the rest. 🤝 Core Modules 🧩 Snippets Manager Backend, Frontend, Persistent, Scheduled, Functions, and in-content (PHP/JS) snippets, all in one clean dashboard with tags, search, scope filters, and priorities. 🪄 AI-Assisted Coding Describe what you want in plain English and let AI Engine write the snippet: code, name, arguments, and scope included. Refine existing code or implement it straight from your comments. 🤖 Functions as AI Tools Every Function snippet becomes a function-calling tool and an MCP tool, so your AI Engine chatbots (and external AI agents) can actually do things on your site, not just talk. 🔀 Functions as Workflow Steps Workflow Engine surfaces each of your functions as its own draggable step. Your custom logic becomes a first-class citizen on the automation canvas. 🌐 External Access (REST) Expose any runnable snippet through a secured REST endpoint with a bearer token. Perfect for Make.com, n8n, webhooks, and scheduled external jobs. 🛡️ Safe Mode A snippet that throws a fatal error is automatically caught and disabled before it can take your site down. Code with confidence. ⏰ Scheduling Run a snippet daily at a chosen time via WP-Cron (reports, cleanups, syncs) without touching the server crontab. 🧱 Code Blocks & Shortcodes (Pro) Drop PHP or JS straight into a post or page with a Gutenberg block or the [code-engine] shortcode, with safety guards. 🧩 Snippets, the way they should be Code Engine organizes your code by scope, so each snippet runs exactly where it belongs: Persistent: runs everywhere (frontend and backend). Your everyday “add this to functions.php” code, but managed. Frontend: runs only on the public site. Backend: runs only in the admin. Function: a named, callable function with typed arguments and defaults. This is the reusable building block (see below). Scheduled: runs on a WP-Cron schedule, at the hour and minute you pick. Content (PHP / JS): runs inside a specific post or page, via a Gutenberg Code Block or the [code-engine] shortcode (Pro). Everything is searchable, taggable, sortable by priority, and importable/exportable. The CodeMirror editor gives you proper syntax highlighting and keyboard shortcuts (Cmd+S to save, Cmd+Enter to run). A nikic/php-parser pass validates your PHP before it ever runs. 🪄 Let AI write it for you Don’t feel like writing the boilerplate? Describe the snippet in plain language and Code Engine, powered by AI Engine, generates the whole thing: the code, a sensible name, a description, the right scope, and, for functions, the argument list with names, types, and defaults. Already have code? Ask the AI to modify it from a prompt, or write a few comments describing what you want and let it fill in the implementation. It’s pair programming, right inside your dashboard. ✨ The big idea: write once, use everywhere This is what makes Code Engine different. A Function snippet is not just code you call from other code. It’s a reusable capability that the rest of your stack can plug into. The moment you save it, the same function is available in three places at once: 1. As an AI tool, for chatbots and AI agents With AI Engine active, your functions are exposed through function calling and over MCP (Model Context Protocol). Your on-site chatbot can run them mid-conversation, and external AI agents (Claude, Claude Code, ChatGPT, OpenClaw) can call them too. Want a chatbot that checks stock, looks up a booking, or kicks off a process? Write the function; the chatbot gains the skill. 2. As a workflow step, for automation With Workflow Engine, every active function shows up in the Add-step picker as its own block, named after your snippet, with one input per argument. Drag it onto the canvas and wire it between other steps: an AI step that summarizes, your function that saves, a Social Engine step that posts. There’s also a generic “Execute snippet (by ID / by name)” step when you want to call one dynamically. You never write integration code; your function is the integration. 3. As a REST endpoint, for the outside world Give a snippet a custom endpoint name and a bearer token, and it’s instantly callable from anywhere: POST /wp-json/code-engine/v1/snippets-endpoint/your-endpoint Pass arguments as JSON in the body, secure it with a token, and trigger it from Make.com, n8n, Zapier, GitHub Actions, or a humble cron job. Automation without a middleware bill. 🛡️ Safe by default Running arbitrary code is powerful, so Code Engine takes safety seriously: Safe Mode catches fatal errors and auto-disables the offending snippet, so a typo never white-screens your site. REST whitelisting means global snippets only run on trusted REST routes by default, so you choose what to open up. Per-snippet tokens secure your external endpoints. Validation with a real PHP parser before code is saved. For developers who want fewer guardrails, there’s a “Bypass REST Security” option and filters (mwcode_rest_authorized, mwcode_rest_whitelist) to tailor exactly what’s allowed. Works beautifully with the Meow Apps family Code Engine is one engine in a connected set, each one useful alone, magical together: AI Engine: chatbots, content generation, and MCP.

Describe the integration you want. The AI builds it. Webhook Actions ships with Build with AI — an in-admin agent that turns a plain-language request like “When a Contact Form 7 form is submitted, send it as JSON to my n8n webhook” into a working, tested automation. The agent proposes a plan you can review and edit, then creates the webhook, captures a real example payload from your site, maps the fields, sets dispatch conditions, probes your endpoint, and sends a test delivery. Nothing goes live without your confirmation — new webhooks are always created disabled, and you can undo the last change with one click. 📖 Full documentation at wpwebhooks.org/docs/ What you can connect Sources — anything in WordPress that fires an action. Webhook Actions turns any do_action into a trigger, so form submissions, WooCommerce orders, user registrations, post publishes and your own custom plugin events can all start an automation. That covers Elementor Forms, WPForms, Forminator, Fluent Forms, Gravity Forms, WooCommerce and your own code — there is no per-plugin add-on to hunt down. Contact Form 7 and IvyForms go one step further with built-in support: their submissions are normalized into clean JSON payloads automatically. Destinations — any HTTP endpoint. The plugin sends outgoing webhooks to anything that accepts a request: an n8n, Make, Zapier or Pabbly webhook node, a Slack or Discord incoming-webhook URL for order and form notifications, Airtable, Google Sheets, Mailchimp, HubSpot, Salesforce, Notion, your CRM, an internal microservice, or an AI agent API. There are no bundled per-service connectors and none are needed — point a webhook at a URL, map the fields, and send. Every delivery is queued, retried on failure and logged with full request and response history. That makes it a no-code way to sync WordPress data outward: describe what you want in chat and let the AI build it, or wire it up by hand in the admin UI. No PHP required either way. Bring your own AI — free options included WordPress 7.0 AI Client — if your site already has an AI provider connected (Settings → Connectors), the builder uses it directly; the plugin stores no keys Your own API key — connect Anthropic, OpenAI, or Google in the builder; keys are encrypted in the Credentials Vault and never returned over the API Free to run — a free Google AI Studio key gives you Gemini at no cost: step-by-step tutorial Automatic fallback — if a provider is rate-limited mid-build, the agent switches to another connected provider and keeps going What the AI works from The agent doesn’t guess — it works from your site’s real data. It maps fields against actually captured payloads, edits existing webhooks by name or id instead of duplicating them, validates endpoints with a guarded probe (SSRF-protected, secrets always redacted), and verifies the result with a real test delivery. Every operation is also published as a WordPress Ability, so external AI tools (Claude Code, Cursor) can drive the same toolset over MCP with scoped API tokens. The engine underneath (free) Turn any WordPress do_action into a first-class automation trigger your CRMs, n8n flows, AI agents, and internal services can consume — every dispatch is an outgoing webhook you fully control Persistent delivery queue with smart retry and exponential backoff — powered by WP-Cron, auto-upgrades to Action Scheduler or System Cron when available, (Pro) External Cron for guaranteed reliability Per-event UUID and ISO 8601 timestamp — enable downstream deduplication Delivery logs with full attempt history, request/response inspection, replay, and bulk retry Synchronous execution mode — fire inline without queue delay Payload mapping — rename, restructure, exclude, and type-cast fields with dot-notation paths Conditional dispatch — filter events by payload field values before dispatch, so a Slack notification or a CRM sync only fires when it should HTTP method, custom headers, and URL query parameters per webhook Dynamic endpoint URLs — {{ field.path }} placeholders resolved at dispatch time (free via fswa_webhook_url filter) Webhook Chains — wire 2xx completions to downstream webhooks with full observability Import & Export — move webhooks and chains between sites as portable JSON (triggers, field mapping, and conditions included; Code Glue with Pro), with strict validation and a per-item result summary on import Markdown descriptions — document what each webhook and chain does inline, with a Write/Preview toggle while editing Credentials Vault — store reusable auth secrets (Bearer, Basic, API key, custom) encrypted at rest; reference them from webhooks instead of pasting raw Authorization headers. Secrets are write-only over the API — never returned, only a masked hint Activity History — persistent audit log of every admin and API-token action Built-in CF7 and IvyForms integrations — structured payloads, no extra plugins Action Scheduler auto-detection — more reliable delivery on high-traffic sites Fully translatable — the entire admin interface and all server-side strings are internationalized; ships with Polish, Simplified Chinese, and Dutch, and is compatible with WPML and Polylang String Translation Full REST API with scoped API token authentication (read / operational / full / agent) — the agent scope grants full write access for AI assistants while never exposing stored secrets Developer extensibility — 16 filters and 7 action hooks (reference) Pro features AI credits included — Build with AI runs through the hosted WP Webhooks AI service on every Pro plan: no API keys to create, no provider accounts, a monthly credit allowance that renews automatically, and a live credits counter in the builder. Your own keys and WordPress connectors stay available any time AI writes Code Glue for you — the agent drafts PHP snippets, test-runs them against your real captured payloads, and assigns them to webhooks (with your confirmation) for pre-dispatch payload enrichment or post-dispatch side effects AI sets advanced conditions — with Pro the agent can propose multi-rule AND/OR condition groups instead of a single rule Code Glue — attach PHP snippets to any webhook+trigger (pre-dispatch payload enrichment, post-dispatch side effects) External Cron — replace unreliable visitor-triggered WP-Cron with a managed external pinger, provisioned automatically on license activation. Two modes: plugin queue endpoint (down to 20 s interval, configurable batch size) or WP-Cron endpoint (60 s, covers all WordPress background work). No server crontab or external dashboard — controlled entirely from wp-admin, with a live heartbeat chart and inline error alerts Unlimited conditions per trigger with AND/OR groups Per-webhook retry limit and backoff strategy overrides Dynamic URL templates — {{ }} syntax with no custom PHP required See pricing and upgrade → Examples Send Contact Form 7 submissions to a webhook (n8n demo) Send Gravity Forms Submissions to n8n Send IvyForms submissions to a webhook (n8n demo) WooCommerce orders to n8n on completion — wired up with a Claude Code agent WooCommerce to HubSpot integration — sync orders, contacts, and deals with no custom code
