§ 00Carrd + Event RSVPplatform-specific integration guide

Why Carrd developers choose splitforms for event rsvp

Carrd's embed element lets you inject custom HTML into your one-page site — perfect for a lightweight contact form. Carrd Pro includes a native form feature, but it caps submissions at 100/month on paid plans and lacks webhook delivery. The event rsvp on this page drops into a Carrd embed, posts to splitforms, and gives you 500 dashboard submissions/month free; Starter adds Slack/Discord notifications. No Carrd Pro upgrade needed for the form to work. The HTML is self-contained — Carrd's minimal runtime handles the display, splitforms handles the backend.

§ 00Quick answerHTML · events

Yes — this is the shortest safe path for Carrd.

Use the HTML snippet on this page, keep the event rsvp fields visible in your Carrd 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 carrd reality

Carrd's Form widget requires Pro Standard ($19/year) just to exist on the page, and even then it doesn't deliver email itself — the form 'works' by posting to an external integration: Mailchimp, SendGrid, Basin, Formspree, etc.

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.

Loved the demo — quick question about pricing on the 3-year plan. Are usage limits per project or account-wide?
§ 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
01

Capture attendance and party

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

02

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.

03

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%.

§ 03cCarrd production notesnative path · deploy · gotchas

What changes when this event rsvp lives in Carrd.

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

without splitforms

Carrd's Form widget requires Pro Standard ($19/year) just to exist on the page, and even then it doesn't deliver email itself — the form 'works' by posting to an external integration: Mailchimp, SendGrid, Basin, Formspree, etc. So the question isn't 'native vs splitforms' but 'which third-party backend do you wire up?'. Mailchimp is overkill (and surprisingly expensive once your list grows); Basin and Formspree limit free submissions; SendGrid requires DNS verification. Splitforms is the same shape of integration (Type: Custom, Method: POST, Action: a URL) at a better free tier and with built-in spam filtering. Carrd's Form widget settings don't change.

deploy notes

Carrd publishes to a *.carrd.co subdomain on every plan; Pro Standard adds a custom domain. The form posts to splitforms from the browser, so neither subdomain nor custom domain matters for delivery. Lock the splitforms access key to BOTH the *.carrd.co URL and your custom domain — Carrd serves the same content under both, with different Origin headers. Carrd's Designer preview never actually POSTs; you have to publish (free) and submit from the live URL to test. Embed elements bypass Carrd's CSS, so the form will look browser-default unless you inline styles.

Carrd gotcha

Pro Standard plan still required for Custom form Type

Carrd's free plan and Pro Lite don't expose the Form widget at all. Pro Standard ($19/yr) unlocks the Form widget with Type → Custom. Splitforms doesn't change Carrd's plan requirements — it just fills in the backend that Carrd doesn't ship.

Carrd gotcha

Embed element forms don't inherit Carrd's site styles

If you paste raw HTML via an Embed element, your form will look like browser-default — no Carrd typography, no site colors. Use the native Form widget for styling, then add a hidden access_key field via Custom fields.

Carrd gotcha

Carrd's success message + splitforms redirect can fight each other

Carrd's Form widget has a built-in success message that shows on 2xx response. If you also set a redirect field in the form, the user sees the success blip then redirects mid-message. Pick one: redirect via splitforms OR Carrd's success text.

Carrd gotcha

The form widget's Field labels don't match input names by default

Carrd uses friendly labels like 'Your name', but the actual input name attribute is name-1 or similar unless you set Custom in the field settings. Set the Custom name to name, email, message — splitforms uses the input names as keys in your inbox.

PATTERN A

Pattern A — native Form widget set to Custom type

In the Form widget's settings, set Type to Custom, Method to POST, Action to the splitforms URL. Add a hidden field access_key via the Custom Fields tab. Carrd handles the styling and mobile layout; splitforms handles delivery. Use the same wiring for the event rsvp fields on this page.

PATTERN B

Pattern B — Embed element with full HTML control

Drop an Embed element into a Carrd section and paste raw HTML. Loses Carrd's auto-styling but lets you add a honeypot, multi-field validation, or custom redirect. Useful for waitlist or job-application forms that exceed the Form widget's capability. Use the same wiring for the event rsvp fields on this page.

§ 06Questions9 answered

Event RSVP on CarrdFAQ.

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

01Does this event rsvp work on Carrd?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any Carrd site without server-side code, plugins, or SDKs. Drop the snippet into a Carrd page or component and submissions land in your splitforms dashboard.
02How much does the event rsvp cost on Carrd?
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 Carrd 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 Carrd 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.
