Instructions
Step 1: Register Webhooks via API
import { WebflowClient } from"webflow-api";
const webflow = newWebflowClient({
accessToken: process.env.WEBFLOW_API_TOKEN!,
});
const siteId = process.env.WEBFLOW_SITE_ID!;
const webhookUrl = "https://your-app.com/webhooks/webflow";
asyncfunctionregisterWebhooks() {
const triggerTypes = [
"form_submission",
"site_publish",
"ecomm_new_order",
"collection_item_created",
"collection_item_changed",
];
for (const triggerType of triggerTypes) {
const webhook = await webflow.webhooks.create(siteId, {
triggerType,
url: webhookUrl,
// form_submission supports filtering to a specific form
...(triggerType === "form_submission" && {
filter: { name: "contact-form" }, // Filter by form name
}),
});
console.log(`Registered: ${triggerType} -> ${webhook.id}`);
}
}
// List existing webhooksasyncfunctionlistWebhooks() {
const { webhooks } = await webflow.webhooks.list(siteId);
for (const wh of webhooks!) {
console.log(`${wh.triggerType}: ${wh.url} (${wh.id})`);
}
}
// Delete a webhookasyncfunctiondeleteWebhook(webhookId: string) {
await webflow.webhooks.delete(webhookId);
}
Step 2: Webhook Endpoint with Signature Verification
# Terminal 1: Start your server
npm run dev
# Terminal 2: Expose via ngrok
ngrok http 3000
# Copy the https:// URL# Terminal 3: Register test webhook
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\": \"form_submission\",
\"url\": \"https://your-ngrok-url.ngrok.io/webhooks/webflow\"
}"# Now submit a form on your Webflow site — the webhook will hit your local server
Output
Webhook registrations for all needed trigger types
HMAC-SHA256 signature verification on every request
Type-safe event router handling all Webflow events
