To integrate Replit with Typeform, you typically either receive data from Typeform (via webhooks) or send data to Typeform’s API (via REST calls). The simplest and most “Replit-native” way is to create a small Node.js server inside your Repl that listens for Typeform webhooks, using Replit Secrets for the credentials, and a workflow or explicit run command to start it.
Typeform supports webhooks, which means when someone submits a form, Typeform can send the data to your URL. In Replit, you host a tiny Express server that can receive this POST request, verify it, and process the data (for example, save it to a database or trigger another API). You can also use the Typeform APIs to create or retrieve forms or responses if you have an API token.

npm install express axios
index.js (or server.js), start an Express app that listens on 0.0.0.0 (this is important for Replit visibility) and a port that you explicitly define, for example process.env.PORT or 3000. Then, register a route like /typeform-webhook that handles Typeform POST payloads.
import express from "express"
import axios from "axios"
const app = express()
app.use(express.json()) // to parse JSON payload
app.post("/typeform-webhook", async (req, res) => {
const payload = req.body
// Typeform sends the submitted data here
console.log("Received Typeform submission:", payload)
// Example: send the response data elsewhere or perform logic
// If you want to fetch submission details via Typeform API:
try {
const responseId = payload.form_response?.token
const result = await axios.get(`https://api.typeform.com/forms/${payload.form_response.form_id}/responses?included_response_ids=${responseId}`, {
headers: {
Authorization: `Bearer ${process.env.TYPEFORM_TOKEN}`
}
})
console.log("Verified response from Typeform API:", result.data)
} catch (err) {
console.error("API error:", err.message)
}
res.sendStatus(200)
})
const PORT = process.env.PORT || 3000
app.listen(PORT, "0.0.0.0", () => {
console.log(`Listening on port ${PORT}`)
})
In practice, integrating Replit with Typeform means making one of two explicit connections: either sending API requests from Replit to Typeform using your TYPEFORM\_TOKEN, or receiving form submissions via a webhook endpoint hosted inside your Repl. Everything is explicit and controlled — secrets are stored in Replit Secrets, ports are bound to 0.0.0.0, and Replit’s live URL acts as your public endpoint. This setup is stable for light-to-medium traffic and perfect for prototypes or internal tools.
1
Use Replit as a live backend that listens for Typeform webhooks. Each time a user submits a form, Typeform sends the form data as a POST request to your Replit server. You bind your Express server to 0.0.0.0 and expose a port like 3000 through the Replit interface. The data can then be stored in a hosted database (like Firebase or Supabase) or in a local Replit persistent file. Secrets (e.g. API keys) are managed using Replit Secrets, so they remain hidden in code.
// index.js
import express from "express"
const app = express()
app.use(express.json())
app.post("/typeform-webhook", (req, res) => {
console.log("New form response:", req.body)
res.sendStatus(200) // Must respond quickly to Typeform
})
app.listen(3000, "0.0.0.0", () => console.log("Server running on port 3000"))
2
Use Replit to connect Typeform’s form data with communication APIs (like SendGrid or Twilio) for automatic follow-ups. The Typeform webhook triggers a Replit endpoint, and the backend script sends an email, SMS, or Slack message. This setup allows quick post-form engagement without manual steps. All tokens and credentials are stored as environment variables in Replit Secrets. You can test the flow by submitting a Typeform and watching the Replit logs for real-time messages.
// index.js
import express from "express"
import fetch from "node-fetch"
const app = express()
app.use(express.json())
app.post("/typeform-hook", async (req, res) => {
const email = req.body.form_response.answers.find(a => a.type === "email")?.email
if(email){
await fetch("https://api.sendgrid.com/v3/mail/send", {
method: "POST",
headers: {
"Authorization": `Bearer ${process.env.SENDGRID_KEY}`,
"Content-Type": "application/json"
},
body: JSON.stringify({
personalizations: [{ to: [{ email }] }],
from: { email: "[email protected]" },
subject: "Thanks for your response!",
content: [{ type: "text/plain", value: "We got your input!" }]
})
})
}
res.sendStatus(200)
})
app.listen(3000, "0.0.0.0", () => console.log("Ready for Typeform webhooks"))

Build an interactive dashboard UI powered by Replit that visualizes data pulled from the Typeform REST API using your personal access token. The frontend (HTML/React) fetches data from your Replit backend, which queries Typeform’s API every time the page loads. You can chart response counts, average times, or display submission summaries. This gives a live analytical view without exporting spreadsheets. Replit ensures live updates, and you can deploy it as a persistent web app.
// server.js
import express from "express"
import fetch from "node-fetch"
const app = express()
app.get("/responses", async (req, res) => {
const resp = await fetch("https://api.typeform.com/forms/{FORM_ID}/responses", {
headers: { Authorization: `Bearer ${process.env.TYPEFORM_TOKEN}` }
})
const data = await resp.json()
res.json(data)
})
app.listen(3000, "0.0.0.0", () => console.log("Dashboard backend running"))

1
Store your Typeform API key inside Replit Secrets by opening the “Secrets” tab (🔑 icon on left sidebar), adding a new secret named TYPEFORM_API_KEY, and pasting the key as the value. This way, the key never appears in your source code. Then access it from your running code using process.env so it stays private, even if the Repl is public or shared.
Replit Secrets act as secure environment variables. They persist across runs but are hidden from anyone viewing the code. They load automatically when the Repl executes. Always read them via code instead of hardcoding values. For example, in Node.js you can safely request Typeform’s API:
import fetch from "node-fetch"
const TYPEFORM_API_KEY = process.env.TYPEFORM_API_KEY
// Make an authorized request to Typeform API
const response = await fetch("https://api.typeform.com/forms", {
headers: { Authorization: `Bearer ${TYPEFORM_API_KEY}` }
})
const data = await response.json()
console.log(data)
2
The Typeform API fetch request fails with a CORS error in Replit because Typeform’s servers reject browser-based (client‑side) requests from unknown origins. Browsers enforce CORS (Cross‑Origin Resource Sharing) to block web pages from directly calling external APIs unless the API allows it via specific headers. Replit hosts frontends on its own domain, so without the proper CORS headers from Typeform, the browser blocks the request before it even reaches Typeform’s endpoint.
To make it work, shift the fetch call from the browser code into your Replit backend (Node.js, Python, etc.). That backend acts as a secure proxy: it sends the request server‑to‑server using your Typeform API key stored in Replit Secrets, then returns the data to your frontend.
// Example Express route in Replit backend
import express from "express"
import fetch from "node-fetch"
const app = express()
app.get("/forms", async (req, res) => {
const r = await fetch("https://api.typeform.com/forms", {
headers: { Authorization: `Bearer ${process.env.TYPEFORM_TOKEN}` }
})
const data = await r.json()
res.json(data)
})
app.listen(3000, "0.0.0.0") // expose port for Replit preview
Then call /forms from your client. This approach aligns with Replit’s explicit workflows and avoids CORS entirely.

To automatically send Typeform responses into your Replit backend or Replit Database, use Typeform’s webhooks. You create a live endpoint in your Repl (for example with Express.js), then register this public URL in your Typeform settings. Each time a form is submitted, Typeform will send a POST request with the response data. Your Replit app receives this JSON payload, processes it, and saves it to the Replit Database or another service.
import express from "express"
import Database from "@replit/database"
const app = express()
const db = new Database()
app.use(express.json())
app.post("/typeform", async (req, res) => {
const response = req.body.form_response // Typeform body structure
await db.set(`response_${response.token}`, response.answers)
res.status(200).send("Saved")
})
app.listen(3000, "0.0.0.0", () => console.log("Webhook listening"))
Expose your Repl’s web server URL and paste it into Typeform → Connect → Webhooks, pointing to /typeform. Now each submission automatically reaches your running Repl, where you can debug and persist data instantly.
Typeform webhooks must reach a publicly accessible endpoint. On Replit, your server must bind to 0.0.0.0 and use the mapped port shown under “Open in new tab” or “Webview”. A common mistake is binding to localhost or not running the server while Typeform tries to send data — webhook requests will silently fail.
import express from "express";
const app = express();
app.use(express.json());
app.post("/typeform", (req, res) => {
console.log(req.body); // handle Typeform submission
res.sendStatus(200);
});
app.listen(process.env.PORT || 3000, "0.0.0.0");
Never hardcode Typeform API tokens or webhook secrets directly in your code. Storing credentials inside files exposes them publicly since Repls are often visible. Instead, use Replit Secrets so credentials load as environment variables at runtime.
TYPEFORM\_TOKEN.process.env.TYPEFORM\_TOKEN inside your code.const res = await fetch("https://api.typeform.com/forms", {
headers: { Authorization: `Bearer ${process.env.TYPEFORM_TOKEN}` }
});
Typeform can sign requests with a secret so you can verify they’re genuine. Many developers skip this step, leaving the endpoint open to fake POSTs. The verification is simple: compute the HMAC-SHA256 of the raw request body using the TYPEFORM\_SECRET and compare it to the signature header.
import crypto from "crypto";
function verifySignature(secret, body, signature) {
const expected = crypto.createHmac("sha256", secret).update(body).digest("base64");
return expected === signature;
}
Replit’s filesystem is ephemeral — code persists, runtime data may not. Developers sometimes store Typeform responses in local JSON files or memory. After a restart, that data disappears. Use a persistent external database (like Supabase, Firebase, or external APIs) for storing form submissions safely.
// Save received Typeform submission to external API
await fetch("https://your-backend.example.com/submissions", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify(req.body)
});
