How to integrate Elfsight Countdown Timer Widget with Webflow

Countdown timers create urgency for product launches, flash sales, and event registrations. Elfsight Countdown Timer Widget integrates with Webflow to display fixed-date countdowns, personalized visitor timers, and number counters across your site.

Use inline embed codes for standard timer implementations or build with Webflow's Custom Code API when you need CMS-driven countdowns or programmatic timer deployment across multiple pages.

Use inline embed and widget code

Add countdown timers to any Webflow page by copying the embed code from your Elfsight dashboard. And pasting the code into a Webflow Custom Embed element.

This method works for Countdown to Date timers, Personal Countdown timers, and Number Counter displays. The timer loads asynchronously and responds to viewport changes automatically.

Timer types you can embed:

• Countdown to Date timers for product launches, webinars, or events where all visitors see the same deadline (with optional daily, weekly, monthly, or yearly repeats)
• Personal Countdown timers that create unique countdowns for each visitor, persisting across sessions for personalized promotions or trial periods
• Number Counter displays that increase or decrease to showcase available seats, subscriber counts, or inventory levels
• Custom styled timers using five built-in templates or CSS overrides

Elfsight widgets are designed to optimize performance through asynchronous loading.

Build with Webflow’s APIs and Elfisght’s widget platform

Connect Webflow's Custom Code API with Elfsight's widget platform when you need programmatic timer control or CMS-driven countdowns. This approach requires custom JavaScript development to coordinate timer behavior with your content.

Use Webflow's REST APIs to manage content and inject timer code programmatically across collection pages or templates.

Manage timer deployment with Custom Code API

Deploy timer scripts across your site using Webflow's Custom Code endpoints. This method centralizes timer management and creates consistent implementations across multiple pages or templates.

The Custom Code API lets you register scripts globally or inject code at page level. Use POST /v2/sites/{site_id}/registered_scripts to add the Elfsight platform script, then control individual timer placement through page-specific custom code with PUT /v2/pages/{page_id}/dom/custom_code.

Custom Code API capabilities:

• Register global scripts with POST /v2/sites/{site_id}/registered_scripts to load Elfsight's platform script across all pages
• Inject page-specific code using PUT /v2/pages/{page_id}/dom/custom_code for timer containers
• Manage site-wide settings with GET /v2/sites/{site_id}/custom_code/registered_scripts to audit timer implementations
• Authenticate requests following Webflow's authentication reference with Bearer tokens

This approach works well when you manage multiple Webflow sites with standardized timer implementations or need to deploy timers programmatically based on business logic.

Create dynamic CMS-driven countdowns

Build countdown timers that pull target dates from Webflow CMS collections. This pattern combines Webflow's CMS API with client-side JavaScript to render timers dynamically and requires custom integration work.

Fetch collection items using Webflow's CMS endpoints, extract date fields, then initialize Elfsight timers with those values through custom JavaScript. Your content team updates dates in the CMS, and timers reflect changes after page refresh or client-side polling.

Implementation pattern:

• Fetch CMS data with GET /v2/collections/{collection_id}/items to retrieve event dates and timer configurations
• Create collection items using POST /v2/collections/{collection_id}/items when adding new events programmatically
• Update timer dates via PUT /v2/collections/{collection_id}/items/{item_id} for event reschedules
• Build custom JavaScript to initialize and control timers based on CMS data

This approach works for event management systems, product launch calendars, or multi-location stores with timezone-specific countdowns. You can create one CMS collection for events and render unique timers on each collection template page.

What you can build

Integrating Elfsight Countdown Timer Widget with Webflow creates time-sensitive experiences across landing pages, product launches, event registrations, and recurring promotional campaigns.

• Product launch pages: Display countdowns across hero sections, product cards, and checkout pages to create urgency for limited-edition releases or pre-order campaigns
• Event registration sites: Build timezone-aware countdowns for webinars, conferences, or workshops that automatically update based on visitor location and CMS-managed event schedules
• Flash sale campaigns: Use recurring timers that reset daily or weekly for promotional cycles
• Membership portals: Show trial expiration timers, beta access countdowns, or feature unlock schedules
