Impulse

Spin the Wheel offers, exit-intent popups, countdown bars, and cookie banners all run on JavaScript, and Webflow does not ship ready-made versions of them. For tracking consent, Webflow's consent guide points to a third-party consent management platform (CMP) app, a CMP provider connected through the APIs, or a banner you build with custom code. Each widget script also needs targeting logic and storage, and someone has to maintain it on every page.

Impulse packages more than 40 widgets in one dashboard. Popups are one part of it; the same app also adds ecommerce bars, chat buttons, galleries and sliders, and trust tools such as cookie consent and age verification. Authorizing the Impulse app from the Marketplace connects the Impulse script to your site, and you then pick a widget in the Impulse dashboard and set its display rules before publishing. Leads collected in a popup form sync to Mailchimp, MailerLite, or GetResponse without an export step.

This integration suits marketers running promotions on Webflow ecommerce sites and agencies that reuse one toolkit across client projects. Solo founders can get lead capture running without a developer. Sites that need a cookie notice or an age gate get both from the same dashboard. Creative teams can use the gallery, slider, timeline, and PDF viewer widgets on portfolio sites.

How to integrate Impulse with Webflow

Impulse is a no-code widget and popup toolkit for websites and ecommerce stores, formerly sold as Plum, and its docs and script still use the Plum name in places. Its catalog groups the widgets into ecommerce tools (announcement, free shipping and countdown timer bars, sales and exit-intent popups, size charts), gamified popups (Spin the Wheel, Scratch Card, Pick a Gift, Lottery Ball), WhatsApp, Messenger and Instagram chat, design widgets (Image Slider, Photo Gallery, Before and After, Logo Showcase), documents (PDF Viewer, PDF FlipBook), and trust tools (Cookie Consent, Age Verification, Content Protection). The product tour says each widget reports views, clicks, and conversion rates in the Impulse dashboard.

Teams use Impulse when a Webflow site needs conversion and trust elements faster than a developer can build them. A retailer launching a holiday sale adds a countdown bar and an exit-intent coupon. A store selling age-restricted products adds an age verification gate.

Installation comes down to how the Impulse script reaches your pages. The Impulse app adds the script when you authorize it and covers every widget without code. Custom code lets you paste the Impulse embed line site-wide, on one page with a Code Embed element, or through Google Tag Manager. Impulse display variables let your own page JavaScript decide when a popup qualifies to show. Start with the app, and add an embed or display variables only when a setup needs tag-manager routing or custom conditions.

Install the Impulse app

The Impulse: 40-in-One App on the Webflow Marketplace is the route Impulse's own Webflow guide documents. Authorizing it connects the Impulse script to your site with no further setup. Installing apps takes the Site manager or Designer role, per Webflow's site roles table. The listing names no required Webflow plan.

To set up the integration:

1. Open the Impulse listing on the Webflow Marketplace and click Add to site. Or open the Apps panel, search for Impulse, and click Install on site.
2. Select the sites or Workspace to authorize. A Workspace authorization covers all of its current and future sites.
3. Sign in to Webflow if prompted, review the requested permissions, and click Authorize app.
4. Impulse opens its Apps page. Choose a template, customize it, and click Save.
5. Publish your site and check the widget on the live domain. If it does not appear, use Verify script connection in the widget's final setup step.

Once authorized, the app gives you these controls in the Impulse dashboard:

• Targeting rules: Widgets can trigger on exit intent, page, time on page, scroll depth, UTM parameters, and visitor location. Impulse's popup guide notes that exit intent works only on desktop.
• Lead sync: Popup form submissions sync to Mailchimp, MailerLite, and GetResponse, the email services Impulse documents.
• Trust widgets: Cookie Consent, Age Verification, and Content Protection install from the same dashboard as the popups.
• Teasers: A small teaser element keeps a campaign visible without opening the full popup.

The permissions on the listing are broad. The app requests read and write access to custom code, Webflow CMS data, forms, pages, sites, assets, users, and the ecommerce store, plus read access to the authorizing user and the site activity log. Webflow does not let you trim an app's permissions, only scope it to one site or a Workspace, per the Webflow Apps overview. To disconnect, go to Site settings > Apps & integrations and click Revoke.

We read the widget bundle Impulse serves on its own Webflow site and found no session-replay or third-party analytics code in it: no Sentry, Hotjar, Clarity, PostHog, Mixpanel, Meta Pixel, or Google Analytics calls. The bundle reports widget views and clicks to Impulse's own server, keeps state in browser storage and cookies, and calls GeoJS, a third-party IP geolocation service, when a geo rule is active or a visitor submits a popup form. It loads with the page, so account for it in your consent setup.

Add the Impulse embed code with custom code

Impulse's Tag Manager guide describes the embed as a single line of JavaScript and gives steps for Google Tag Manager, not for Webflow specifically. Use the embed instead of the app when every script on your site runs through a tag manager, or when a widget should load on one page only. Pasting custom code needs a Core, Growth, Agency, or Freelancer Workspace, or an active Site plan.

Paste the embed code into Site settings

1. Site-wide placement puts the Impulse script on every page. In the Impulse dashboard, open the account menu at the top right, select Your Embed Code, and copy the line.
2. The Custom code in head and body tags article covers both locations. Go to Site settings > Custom code, paste it into Head code or Footer code, and click Save changes.
3. Each code section accepts up to 50,000 characters. The script runs in preview but is not live until you publish. Publish the site, then click Verify script connection in Impulse.

Add the embed to one page with a Code Embed element

1. A Code Embed element scopes the script to a single page. Use it for a landing page that needs a Spin the Wheel popup and nothing else. Impulse's Tag Manager guide notes that it counts page views on every page where the script loads, so scoping the script also narrows what counts toward your Impulse pageview allowance. Open the Add panel and drag a Code Embed element onto the page.
2. Paste the embed line, then save and close the modal.
3. Publish the site and verify the connection in Impulse. Code Embed content will not run in expand canvas view, so check the published page rather than the canvas.

Load the embed through Google Tag Manager

1. Use this route if your team already manages marketing tags in one Google Tag Manager container. First, paste your GTM container snippet into Head code at Site settings > Custom code and publish. Create a new tag and choose Custom HTML.
2. Paste the embed code.
3. Select Support document.write.
4. Set the trigger to All Pages or Some Page Views. Pages outside the trigger you chose will not show popups.
5. Submit and publish the container.

Control popup display with Impulse display variables

Impulse's help center documents no public API or webhooks. It does document one client-side object for display conditions, which runs in page JavaScript and needs no server-side code. Use it when a popup should appear only for visitors your own page logic identifies.

Set popup display conditions with window.plumPopupVariables

Impulse's popup guide documents window.plumPopupVariables = {field1: value1, field2: value2…}. The object controls display conditions from your own code.

To implement this:

1. Add a Code Embed, or a Head code block in Site settings > Custom code. Put <script>window.plumPopupVariables = {field1: value1, field2: value2};</script> in it, with your own field names and values.
2. In the popup's Rules and Triggers tab, add a Variables condition with the same field names and values.
3. Publish the Webflow site and confirm the behavior on the live domain.

Test each condition on the published site before you launch the popup.

What you can build with the Impulse Webflow integration

These builds pair Impulse widgets with Webflow pages you already have.

• Gamified email capture: A Spin the Wheel popup on exit intent rewards a discount code for an email. The lead lands in Mailchimp through Impulse's native sync.
• Urgency on product pages: A Countdown Timer Bar and a Free Shipping bar sit above a product grid rendered with a Collection List. The countdown bar runs to the sale's end.
• Age and consent gates: An Age Verification gate and a Cookie Consent banner run on a Webflow store selling age-restricted products. Display rules scope each widget by page.
• Portfolio and content presentation: A creative studio presents case studies with a Before and After slider, Timeline, Logo Showcase, and PDF Viewer. You style each widget to match brand fonts and colors.

Popup leads and native form leads can land in the same list. To set up the Webflow form side, add a Mailchimp newsletter next to your Impulse popups.
