How do you send Svelte / SvelteKit form submissions to Form2Lead?

Use Form2Lead endpoints in Svelte and SvelteKit apps to process lead submissions reliably — a single fetch() POST, no SDK, no server code required.

Why use Form2Lead with Svelte / SvelteKit?

SvelteKit ships static by default with adapters like @sveltejs/adapter-static. Form2Lead keeps your SvelteKit app static while handling form submission backend work — spam filtering, email notifications, and a searchable lead dashboard.

Prerequisites

✔Svelte / SvelteKit project
✔Form2Lead endpoint URL

Step-by-Step Integration Guide

01. Bind Form Submission in Svelte

Post FormData to Form2Lead on submit.

<script>
  let submitting = false;
  let success = false;

  async function handleSubmit(e) {
    submitting = true;
    const formData = new FormData(e.target);
    const res = await fetch('https://form2lead.com/api/v1/f/YOUR_FORM_ID', {
      method: 'POST',
      body: formData,
      headers: { 'Accept': 'application/json' }
    });
    submitting = false;
    if (res.ok) success = true;
  }
</script>

{#if success}
  <p>Submission received!</p>
{:else}
  <form on:submit|preventDefault={handleSubmit}>
    <input name="name" required placeholder="Name" />
    <input name="email" type="email" required placeholder="Email" />
    <button type="submit" disabled={submitting}>Submit</button>
  </form>
{/if}

02. Add the Honeypot Spam Field

Include a hidden `_gotcha` input so Form2Lead silently drops automated bot submissions.

<input type="text" name="_gotcha" style="display:none !important" tabindex="-1" autocomplete="off" />
