§ 00Webflow + Event RSVPplatform-specific integration guide

Why Webflow developers choose splitforms for event rsvp

Webflow's built-in form block sends to Webflow's own backend, which caps at 100 submissions/month on the free plan and lacks webhook delivery, CC recipients, and spam filtering. The event rsvp on this page bypasses that entirely — paste it into a custom embed element, set the form action to splitforms, and you get 500 dashboard submissions/month with AI spam filtering; Starter adds Slack/Discord webhooks. Webflow's native interactions (success message, loading state) still work if you use <code>fetch</code> instead of a native form submit.

§ 00Quick answerHTML · events

Yes — this is the shortest safe path for Webflow.

Use the HTML snippet on this page, keep the event rsvp fields visible in your Webflow UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML version, then replace YOUR_ACCESS_KEY.

The posted payload contains your name, email, will you attend?, how many guests are you bringing?, dietary preferences. Required fields are your name, email and will you attend?.

native webflow reality

use case fit

Eventbrite charges 3.7% + $1.79 per ticket. For a free event, fundraiser, or private gathering, the RSVP form does the same job for $0 — and lives on your own domain.

§ 03bEvent RSVP Form (Public / Private Events)template-specific playbook

The reason this event rsvp exists.

Webhooks into Notion / Airtable / Google Sheets · auto .ics calendar invite.

why it matters

Eventbrite, Splash, and Hopin take 3-7% of every paid ticket and charge subscription fees for the white-label option. For free events (fundraisers, private parties, conferences with sponsor-only revenue, weddings), the platform fees are pure waste. The RSVP form captures attending yes/no, guest count, plus-one names, dietary restrictions, and any custom fields (workshop preference for conferences, song requests for weddings). Webhook to a Notion / Airtable / Google Sheet for the running headcount, plus an automatic confirmation email. Final headcount goes to catering 5-7 days out, same as any platform would deliver.

route the submission

Capture attendance and party

Required: attending yes/no, guest count, plus-one names if applicable. Optional: dietary restrictions, song requests, workshop preference, accessibility needs.

Update the running list

Webhook to a Notion / Airtable / Google Sheet that the host references. Each RSVP appends a row; conditional formatting highlights special diets. Real-time headcount without spreadsheet work.

Confirm via email

Auto-respond with confirmation, event details, and a calendar invite (.ics file). Most guests forget the date once they've RSVP'd — calendar adds reduce no-shows by 30-40%.

§ 03cWebflow production notesnative path · deploy · gotchas

What changes when this event rsvp lives in Webflow.

These notes come from the Webflow platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

Webflow's built-in Forms feature delivers submissions to your Webflow project dashboard and emails them — but the free Site plan caps submissions (50 per site, lifetime, on legacy plans) and webhooks are gated behind the Workspace plan ($24/mo+). Worse, the form fails silently if you exceed the cap: users see the 'success' state, your inbox gets nothing. There's no API to inspect submissions programmatically below the Workspace tier, and CMS-driven forms inherit the same caps. Native is fine for a personal portfolio with three submissions a year; for any real lead capture, you need an external endpoint. Splitforms is that endpoint without the plan upgrade.

deploy notes

Webflow hosts your published site on its own CDN — there's no Vercel/Netlify config to worry about. The form posts cross-origin to splitforms regardless. Disable Webflow's built-in hCaptcha for the form (Form Settings → Spam Filter → Off) — it intercepts submissions client-side before splitforms is reached. Lock the splitforms access key to BOTH your *.webflow.io staging URL and your custom domain in the dashboard; Webflow serves both, with different Origin headers. Custom code embeds count toward Webflow's per-page code limit (10 KB) — keep raw-HTML Embed forms tight if you have multiple per page.

Webflow gotcha

Webflow strips custom hidden inputs from native Form Blocks

If you add <input type="hidden" name="access_key"> directly in Designer's Form Block, Webflow ignores it on publish. Use the Form Block's settings panel: Form Settings → Form Name + add custom attribute. Or use an Embed element with raw HTML if you need full control.

Webflow gotcha

Default action URL gets reset on every Designer save

Setting the Action URL to https://splitforms.com/api/submit in the Form Block sometimes reverts to Webflow's default after a publish. The fix: lock it in by adding a custom attribute action to the form element (Settings → Element Settings → Custom Attribute).

Webflow gotcha

Method must be set to POST in the form's settings, not the URL

Webflow forms default to GET. Open the form's Settings panel, change Method to POST. If you forget, the submission posts your fields as URL query params — splitforms returns a 405 Method Not Allowed.

Webflow gotcha

Webflow's success/error elements still trigger on AJAX submit

Webflow auto-shows the .w-form-done div on a 2xx response. That's good — but if you also set up a redirect field in splitforms, the user sees the success message for ~80ms before the redirect fires. Either remove the success div or skip the redirect field.

PATTERN A

Pattern A — native Form Block with overridden action URL

Use Webflow's drag-and-drop Form Block — keep the styling, structure, and Designer integration. In Form Settings, change Action to https://splitforms.com/api/submit and Method to POST. Add a hidden access_key field via the form's settings panel. Submissions skip Webflow's backend entirely. Use the same wiring for the event rsvp fields on this page.

pattern-a.htmlhtml8 lines

01<!-- After saving in Designer, the published HTML looks like: -->
02<form action="https://splitforms.com/api/submit" method="POST">
03  <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />
04  <input type="text"  name="name" required />
05  <input type="email" name="email" required />
06  <textarea name="message" required></textarea>
07  <input type="submit" value="Send" />
08</form>

PATTERN B

Pattern B — Embed element with raw HTML

If you need full control over markup (custom honeypot, file upload, multi-step), drop an Embed element on the canvas with raw HTML. Skips Webflow's form widget entirely. Useful for forms that don't fit the Designer's mental model. Use the same wiring for the event rsvp fields on this page.

§ 06Questions9 answered

Event RSVP on Webflow — FAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this event rsvp work on Webflow?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any Webflow site without server-side code, plugins, or SDKs. Drop the snippet into a Webflow page or component and submissions land in your splitforms dashboard.

02How much does the event rsvp cost on Webflow?

Free for 500 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.

03Can I customize the fields?

Yes. The template ships with sensible defaults (your name, email, will you attend?, how many guests are you bringing?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the event rsvp?

A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on Webflow as on any other framework.

05Can I send the event rsvp submissions to Slack or Discord?

Yes. Webhooks are available on Starter and above, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.

06Will it work on a static Webflow site?

Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.

07Why not just use Eventbrite or Splash?

For free events, both charge subscription fees ($30-100/mo for white-label) plus per-ticket fees. The form costs $0, lives on your own domain (which matters for weddings and brand events), and the data is yours — not licensed inside their platform.

08Can I send a calendar invite (.ics) automatically?

Yes — generate an .ics file and attach to the auto-responder. Webhook to a Zapier / Make automation that crafts the .ics with event title, date, location, and notes. Most email clients render the attachment as 'add to calendar' inline.

09How do I handle plus-ones?

Add 'plus-one yes/no' and a name field that appears conditionally. For weddings, the 'plus-one allowed' is invitation-specific — capture invitation code on the form, and the webhook validates whether that invite includes a plus-one before accepting the second name.
