API & integrations

Form backend API for HTML, React, and Next.js

Formiix is a drop-in form backend. POST JSON to one endpoint with your API key. Use the hosted builder, or keep your own UI and let Formiix store and analyze submissions.

Submit endpoint

https://formiix.site/api/submit accepts JSON. Authenticate with x-api-key or the key query parameter.

Email notifications

Optionally email yourself when a new submission arrives. Formiix stores the response in your dashboard; you can export JSON when you need it elsewhere.

No SDK required

If you can call fetch, you can use Formiix. Copy a snippet below and replace the API key from your dashboard.
