§ 00Quick answerReact / Next.js · marketing

Yes — this is the shortest safe path for Next.js.

Use the React / Next.js snippet on this page, keep the lead magnet download fields visible in your Next.js UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the React / Next.js version, then replace YOUR_ACCESS_KEY.

The posted payload contains first name, work email, company, what's your role?. Required fields are first name and work email.

native next.js reality

Without splitforms, you'd write a route handler at app/api/contact/route.ts, parse the FormData, configure SMTP via nodemailer or Resend (~10 minutes of secrets wrangling), add a Postgres or SQLite store for submissions, and then bolt on rate limiting, a honeypot check, an email-classifier or reCAPTCHA, and webhook fan-out.

use case fit

Ungated content gets read; gated content builds your list. The lead-magnet form trades the PDF for an email plus 1-2 qualifying questions, so the nurture sequence segments by intent.

§ 03bLead Magnet Download Form (Ebook / PDF / Checklist Gate)template-specific playbook

The reason this lead magnet download exists.

Multi-step (Typeform-style) · webhooks into ConvertKit / HubSpot / Mailchimp.

why it matters

Lead magnets — ebooks, checklists, templates, swipe files, mini-courses — are the workhorse of B2B content marketing. Gated downloads convert at 25-50% of landing-page visitors (vs 1-2% for newsletter signups), but only when the magnet is truly valuable. The form captures email plus 1-2 qualifying questions ('what's your role?', 'what's your team size?') so the nurture sequence segments by intent. Multi-step boosts completion vs a single form. After submit, the user is redirected to the PDF or it's emailed via webhook + auto-responder. Push the email to your ESP segmented by lead-magnet topic — that's how content marketers build audience taxonomies that actually convert downstream.

route the submission
01

Step 1: capture email

Single email field — frictionless step 1. Once the email is in, momentum carries through later qualifying questions.

02

Step 2-3: qualify role / team

One or two questions on role and team size. Optional but most users complete because they're invested. Each answer becomes a tag in the ESP for downstream segmentation.

03

Deliver the magnet

Auto-respond with the PDF link (or redirect to a thank-you page that auto-downloads). Webhook to ConvertKit / HubSpot / Mailchimp into a 'lead-magnet:[topic]' audience for the nurture sequence.

§ 03cNext.js production notesnative path · deploy · gotchas

What changes when this lead magnet download lives in Next.js.

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

without splitforms

Without splitforms, you'd write a route handler at app/api/contact/route.ts, parse the FormData, configure SMTP via nodemailer or Resend (~10 minutes of secrets wrangling), add a Postgres or SQLite store for submissions, and then bolt on rate limiting, a honeypot check, an email-classifier or reCAPTCHA, and webhook fan-out. Server actions made the wiring slightly tidier in Next 14+, but the operational cost stays the same: a function with a runtime, a database, an outbound email provider, an inbox to monitor, and your name on the spam-filter incident report. Splitforms collapses all of that into a POST to a single URL.

deploy notes

On Vercel, the form works on every plan tier — server actions and client components both run inside the same edge/serverless function. Don't put the splitforms fetch inside a Vercel cron or background function (it's user-facing, latency matters). On Netlify with the Next runtime, server actions need the latest @netlify/plugin-nextjs (≥5.6). For self-hosted / Docker: configure output: 'standalone' in next.config.ts and pass SPLITFORMS_KEY as a runtime env var — never bake it into the image. For static export (output: 'export'), use the client-component path only — server actions aren't supported in static mode.

Next.js gotcha

Don't expose your access key client-side without domain locking

Inlining access_key in a "use client" component makes the key visible to anyone who views source. That's fine if you've enabled allowed-domains in your Splitforms dashboard (Settings → Security) — anyone copying the key from your bundle can't use it from a different origin. If you haven't, use a server action so the key stays on the server.

Next.js gotcha

Server actions need `'use server'` and a real form, not fetch

If you submit to a server action via <form action={myAction}>, Next handles the FormData serialization for you. If you call the action manually with fetch, you have to set the right Content-Type and stringify yourself. Pick one path and stick with it — mixing causes 'Server Action invalid' errors.

Next.js gotcha

App Router + Suspense + useSearchParams = static-prerender bailout

If your form reads ?next=/something to support post-submit redirects, useSearchParams forces the page out of static generation. Either wrap the inner component in a <Suspense fallback={<Skeleton/>}> so the wrapper still prerenders, or accept dynamic rendering for the form route only.

Next.js gotcha

Vercel Edge runtime can't read FormData from `multipart/form-data`

If your route handler uses export const runtime = 'edge' and the form posts as multipart (file inputs), it'll silently miss fields. Use application/x-www-form-urlencoded or remove the edge runtime declaration.

PATTERN A

Pattern A — server action (no client JS, key stays server-side)

Form posts to a server action; the action appends the access key from process.env.SPLITFORMS_KEY and proxies to splitforms. Works without JavaScript, key never reaches the bundle. Use the same wiring for the lead magnet download fields on this page.

pattern-a.tsxtsx10 lines
01// app/actions/contact.ts
02"use server";
03import { redirect } from "next/navigation";
04 
05export async function submitContact(formData: FormData) {
06  formData.append("access_key", process.env.SPLITFORMS_KEY!);
07  const res = await fetch("https://splitforms.com/api/submit", { method: "POST", body: formData });
08  if (!(await res.json()).success) throw new Error("Submission failed");
09  redirect("/thanks");
10}
PATTERN B

Pattern B — client component with fetch and inline status

'use client' component using useState for a 4-state status machine. Lets you show a spinner, inline errors, optimistic resets — at the cost of a hydration boundary. Use NEXT_PUBLIC_SPLITFORMS_KEY and rely on splitforms' domain-locking for safety. Use the same wiring for the lead magnet download fields on this page.

pattern-b.tsxtsx17 lines
01"use client";
02import { useState } from "react";
03export default function ContactForm() {
04  const [s, setS] = useState<"idle" | "loading" | "ok" | "err">("idle");
05  return (
06    <form onSubmit={async (e) => {
07      e.preventDefault(); setS("loading");
08      const fd = new FormData(e.currentTarget);
09      fd.append("access_key", process.env.NEXT_PUBLIC_SPLITFORMS_KEY!);
10      const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
11      setS((await r.json()).success ? "ok" : "err");
12    }}>
13      <input name="email" type="email" required />
14      <button disabled={s === "loading"}>{s === "loading" ? "…" : "Send"}</button>

§ 06Questions9 answered

Lead Magnet Download on Next.js — FAQ.

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

01Does this lead magnet download work on Next.js?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any Next.js site without server-side code, plugins, or SDKs. Drop the snippet into a Next.js page or component and submissions land in your inbox via splitforms.com.
02How much does the lead magnet download cost on Next.js?
Free for 1,000 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 4-year plan (15,000 submissions/mo for 48 months). The same pricing applies regardless of which framework hosts the form.
03Can I customize the fields?
Yes. The template ships with sensible defaults (first name, work email, company, what's your role?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.
04How does spam protection work on the lead magnet download?
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 Next.js as on any other framework.
05Can I send the lead magnet download submissions to Slack or Discord?
Yes. Webhooks are free on every plan, 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 Next.js 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.
07Should I redirect to the PDF or email it?
Email it. Redirects to a Drive / S3 link mean the user gets the PDF without confirming the email — and the email might be a typo or a temporary address. Email delivery confirms the address by requiring an open. Add a 'didn't get it?' resend button on the thank-you page for the rare typo case.
08Can I integrate with ConvertKit / HubSpot / Mailchimp?
Yes — webhook the JSON into the ESP. ConvertKit's 'tags' map naturally to lead-magnet topics; HubSpot's 'lists' do the same. The nurture sequence triggers on tag-add and the topic-specific drip starts immediately. Most B2B teams use this exact pattern.
09Is gating content GDPR-safe?
If you have EU visitors, the consent for marketing email needs to be explicit and unbundled — meaning a separate checkbox 'I want to receive emails about [topic]' that's not pre-checked and not bundled with 'I accept the download'. Bundled consent has been challenged in EU rulings; unbundled is the safe play.
