How it works

Up in 3 steps

No tutorials, no docs deep-dives. You will be live in under two minutes.

Create a workspace

Create a form

Inside your workspace, create a form. Submito generates a unique slug URL that is your submission endpoint.

Send & receive

From your server, POST to the slug URL with your API key. Submissions land in your inbox and dashboard instantly.

route.ts

await fetch("https://submito.dev/api/v1/my-slug/submit", {
  method: "POST",
  headers: {
    "x-api-key": process.env.SUBMITO_API_KEY,
    "Content-Type": "application/json",
  },
  body: JSON.stringify(formData),
});

FAQ

Common questions

Do I need a backend or server?: Yes. Submito is a backend-to-backend API. Your server collects the form data and forwards it to Submito via a POST request with your API key. This keeps your key secure and your integration clean.
What kind of data does it support?: Any JSON payload your server sends — contact forms, newsletter signups, feedback, surveys, order data. If you can serialize it, Submito handles it.
Does it work with my framework?: Yes. Submito works with any server-side framework — Next.js server actions, Express, Fastify, Laravel, Django, and more. If it can make an HTTP POST request, it integrates with Submito.
Is there a free plan?: Yes. The free plan includes 100 submissions per month. Early-access members on the waitlist also get 50% off the annual Pro plan when we launch.
How does spam protection work?: Submito enforces rate limiting at the API level on every request. Abuse is blocked server-side before a submission is ever processed — no captcha or extra client-side configuration needed.
