Introducing the Forminit Python SDK

By Forminit in Changelog • Published February 28, 2026

We’re releasing the official Python SDK for Forminit. Handle form submissions from any Python application — Flask, Django, FastAPI, or plain Python.

Install

pip install forminit

Requires Python 3.8+.

Quick example

import os
from forminit import ForminitClient

client = ForminitClient(api_key=os.environ["FORMINIT_API_KEY"])

response = client.submit("YOUR_FORM_ID", {
    "fi-sender-fullName": "John Doe",
    "fi-sender-email": "john@example.com",
    "fi-text-message": "Hello from Python!",
})

if response.get("error"):
    print("Error:", response["error"]["message"])
else:
    print("Submission ID:", response["data"]["hashId"])

That’s it. Your form data is now in the Forminit dashboard with email notifications, validation, and everything else handled automatically.

Works with your framework

The SDK supports both sync and async usage, so it fits right into whatever you’re already using:

  • Flask — Use request.form.to_dict() and submit directly
  • Django — Use request.POST.dict() and submit directly
  • FastAPI — Use the async client for non-blocking submissions

Tracking included

Pass UTM parameters and ad click IDs to keep attribution data with every submission:

response = client.submit("YOUR_FORM_ID", form_data, tracking={
    "utm_source": "google",
    "utm_medium": "cpc",
    "gclid": "EAIaIQobChMI...",
})
