Nextial Form Events

Descripció

Before you install, you need: one of the supported form plugins, a ChatGPT plan with Work chats and custom MCP servers (ChatGPT Plus or higher), and a site on HTTPS. Without Work chats ChatGPT can read your form entries but cannot react to new ones.

Nextial Form Events connects your WordPress forms to ChatGPT with MCP Events, the way ChatGPT reacts when something happens in a connected app. Each time a visitor submits a form, your site sends ChatGPT a signed notification and ChatGPT does what you asked it to, in plain language:

• «When someone fills in my contact form, tell me if it is a real lead and draft a reply in my tone.»
• «When a quote request arrives, estimate the budget and list what is missing.»
• «Ignore messages that look like sales pitches, and tell me about the rest.»

ChatGPT subscribes to the event, your site notifies it the moment a form is submitted, and ChatGPT does the rest. No Zapier, no polling, no code.

Supported form plugins

• Contact Form 7
• WPForms (Lite and Pro)
• Fluent Forms
• Gravity Forms
• Formidable Forms
• Ninja Forms

You choose which forms notify ChatGPT and which fields are never sent.

Event

• form.submitted – a visitor submitted a form. ChatGPT can listen to all forms, one form (form_id) or one plugin (plugin). Free, no limits.

Read-only tools

ChatGPT can look things up when it needs more context: list_forms, list_recent_submissions (for example «has this person written before?») and get_submission. Only submissions sent to ChatGPT, or kept while an assistant you authorised is connected, are available (the last 50, up to 30 days). With since, an assistant without live events (for example a Claude scheduled task) can ask only for what arrived since its last check. Nextial Form Events never changes your site or your form entries.

Privacy and security

• You choose what is sent. Untick forms you don’t want ChatGPT to see, and list fields that must never be sent.
• Password, file-upload, credit-card, payment, CAPTCHA and the form plugins’ technical fields are never sent.
• Entries your form plugin marks as spam are never sent.
• Sign in with OAuth: ChatGPT opens your site, you log in and press Allow. Disconnect at any time from Settings → Nextial Form Events; tokens and subscriptions are removed at once.
• The last 50 submissions (at most 30 days) are kept only while ChatGPT is subscribed or an assistant you authorised is connected, so it can look them up.
• Only administrators can connect the site.
• Every notification is signed (Standard Webhooks, HMAC-SHA256). Callbacks are verified with a challenge before any data is sent.
• Outgoing requests go only to public HTTPS addresses (no private networks, no redirects).
• ChatGPT is told that field values are written by visitors and must be treated as data, not as instructions.

Built-in tests

The settings page has a self-test (subscribe → verify → signed delivery → unsubscribe on your own site), a «listen for real form submissions» mode, an OAuth check and a delivery log.

Requirements

• One of the supported form plugins.
• A ChatGPT plan that includes Work chats and custom MCP servers (developer mode). On plans without Work chats ChatGPT can use the read-only tools but cannot subscribe to events.
• For OAuth sign-in: pretty permalinks (any setting other than «Plain»). Without them you can still connect with a secret URL.
• Your site must be reachable over HTTPS.

From the makers of Nextial Order Events for WooCommerce. Both plugins can run on the same site.

External services

Nextial Form Events does not contact any service on its own. It only talks to the AI assistant (MCP client) that you connect and approve:

• Event notifications. When ChatGPT – or another MCP client you connected – subscribes to an event, it gives Nextial Form Events a webhook URL (for ChatGPT, on connectors.api.openai.com). Each time a form is submitted, Nextial Form Events sends that URL a signed JSON message with: the form plugin, form ID and title, the entry ID (if the form plugin stores entries), the submitted field names, labels and values (except the ones excluded above), the page URL, the date and a link to the entry or form in your admin. Before the first message the URL is verified with a signed challenge.
• Read-only tools. When the assistant calls a tool, the response contains your list of forms or submissions that were already sent as events.
• Client identification. When an assistant connects with OAuth and identifies itself with a Client ID Metadata Document (ChatGPT uses https://chatgpt.com/oauth/client.json), Nextial Form Events downloads that public JSON file to check the app’s name and allowed redirect addresses. Nothing about your site is sent in that request.

No data is sent until an administrator connects an assistant and it subscribes to events or calls a tool. Form submissions contain personal data written by your visitors: mention in your privacy policy that form entries may be processed by the AI assistant you use. When you connect ChatGPT, OpenAI’s terms and privacy policy apply to the data it receives: Terms of use, Privacy policy.
