Webflow deploy integration

Webflow Deploy Integration

Overview

Deploy Webflow Data API v2 integrations to Vercel, Fly.io, or Google Cloud Run with secure token management, health checks, and webhook endpoint configuration.

Prerequisites

• Working Webflow integration (tested locally)
• Production API token with minimal scopes
• Platform CLI installed (vercel, fly, or gcloud)

Instructions

Vercel Deployment

# Store Webflow secrets in Vercel
vercel env add WEBFLOW_API_TOKEN production
vercel env add WEBFLOW_SITE_ID production
vercel env add WEBFLOW_WEBHOOK_SECRET production

# Link and deploy
vercel link
vercel --prod

// vercel.json
{
  "env": {
    "WEBFLOW_API_TOKEN": "@webflow-api-token",
    "WEBFLOW_SITE_ID": "@webflow-site-id"
  },
  "functions": {
    "api/**/*.ts": {
      "maxDuration": 30
    }
  },
  "headers": [
    {
      "source": "/api/webhooks/webflow",
      "headers": [
        { "key": "Access-Control-Allow-Origin", "value": "https://api.webflow.com" }
      ]
    }
  ]
}

Vercel serverless function for webhook endpoint:

// api/webhooks/webflow.ts (Vercel Edge/Serverless)
import type { VercelRequest, VercelResponse } from "@vercel/node";
import crypto from "crypto";

export default async function handler(req: VercelRequest, res: VercelResponse) {
  if (req.method !== "POST") {
    return res.status(405).json({ error: "Method not allowed" });
  }

  // Verify webhook signature
  const signature = req.headers["x-webflow-signature"] as string;
  const rawBody = JSON.stringify(req.body);
  const expected = crypto
    .createHmac("sha256", process.env.WEBFLOW_WEBHOOK_SECRET!)
    .update(rawBody)
    .digest("hex");

  if (signature !== expected) {
    return res.status(401).json({ error: "Invalid signature" });
  }

  const { triggerType, payload } = req.body;
  console.log(`Webhook received: ${triggerType}`);

  // Handle different trigger types
  switch (triggerType) {
    case "form_submission":
      await handleFormSubmission(payload);
      break;
    case "ecomm_new_order":
      await handleNewOrder(payload);
      break;
    case "site_publish":
      await handleSitePublish(payload);
      break;
  }

  res.status(200).json({ received: true });
}

Fly.io Deployment

# fly.toml
app = "my-webflow-app"
primary_region = "iad"

[env]
  NODE_ENV = "production"
  PORT = "3000"

[http_service]
  internal_port = 3000
  force_https = true
  auto_stop_machines = "suspend"
  auto_start_machines = true
  min_machines_running = 1

  [[http_service.checks]]
    grace_period = "10s"
    interval = "30s"
    method = "GET"
    path = "/api/health"
    timeout = "5s"

# Set Webflow secrets
fly secrets set WEBFLOW_API_TOKEN=your-prod-token
fly secrets set WEBFLOW_SITE_ID=your-site-id
fly secrets set WEBFLOW_WEBHOOK_SECRET=your-webhook-secret

# Deploy
fly deploy
fly status

Google Cloud Run Deployment

# Dockerfile
FROM node:20-slim AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

FROM node:20-slim
WORKDIR /app
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/package.json ./

EXPOSE 3000
CMD ["node", "dist/index.js"]

# Store secrets in GCP Secret Manager
echo -n "your-prod-token" | \
  gcloud secrets create webflow-api-token --data-file=-

echo -n "your-site-id" | \
  gcloud secrets create webflow-site-id --data-file=-

# Build and deploy
gcloud builds submit --tag gcr.io/$PROJECT_ID/webflow-service

gcloud run deploy webflow-service \
  --image gcr.io/$PROJECT_ID/webflow-service \
  --region us-central1 \
  --platform managed \
  --allow-unauthenticated \
  --set-secrets="WEBFLOW_API_TOKEN=webflow-api-token:latest,WEBFLOW_SITE_ID=webflow-site-id:latest" \
  --min-instances=1 \
  --max-instances=10

Register Webhook After Deployment

Once deployed, register your webhook URL with Webflow:

# Get your deployed URL
WEBHOOK_URL="https://your-app.vercel.app/api/webhooks/webflow"

# Register webhooks for the events you need
for TRIGGER in form_submission site_publish ecomm_new_order; do
  curl -X POST "https://api.webflow.com/v2/sites/$WEBFLOW_SITE_ID/webhooks" \
    -H "Authorization: Bearer $WEBFLOW_API_TOKEN" \
    -H "Content-Type: application/json" \
    -d "{
      \"triggerType\": \"$TRIGGER\",
      \"url\": \"$WEBHOOK_URL\"
    }"
  echo " -> Registered $TRIGGER"
done

# Verify webhooks registered
curl -s "https://api.webflow.com/v2/sites/$WEBFLOW_SITE_ID/webhooks" \
  -H "Authorization: Bearer $WEBFLOW_API_TOKEN" | jq '.webhooks[].triggerType'

Health Check Endpoint

// api/health.ts — works on all platforms
import { WebflowClient } from "webflow-api";

export async function healthCheck() {
  const checks: Record<string, any> = {};
  const start = Date.now();

  // Webflow API connectivity
  try {
    const webflow = new WebflowClient({
      accessToken: process.env.WEBFLOW_API_TOKEN!,
    });
    const { sites } = await webflow.sites.list();
    checks.webflow = {
      status: "connected",
      sites: sites?.length,
      latencyMs: Date.now() - start,
    };
  } catch (error: any) {
    checks.webflow = {
      status: "disconnected",
      error: error.statusCode,
      latencyMs: Date.now() - start,
    };
  }

  return {
    status: checks.webflow.status === "connected" ? "healthy" : "degraded",
    services: checks,
    env: process.env.NODE_ENV,
    timestamp: new Date().toISOString(),
  };
}

Output

• Application deployed to chosen platform
• Webflow API token securely stored as platform secret
• Webhook endpoints registered and verified
• Health check endpoint monitoring Webflow connectivity
• HTTPS enforced on all endpoints

Error Handling

Issue	Cause	Solution
Secret not found at runtime	Wrong secret name	Verify with fly secrets list or vercel env ls
Webhook 401	Signature mismatch	Check WEBFLOW_WEBHOOK_SECRET matches
Cold start timeout	Webflow API slow on first call	Set min instances > 0
Health check fails	Token not loaded	Verify secret mounting in container
Deploy timeout	Large image	Use multi-stage Docker build
