How to Use the Vimeo Player API to Control Video on Your Website

If you've ever embedded a Vimeo video and wished you could actually control it with JavaScript, the Vimeo Player API is what you're looking for. Not just play and pause. Things like triggering playback based on user actions, pausing one video when another starts, or resetting a video back to the beginning when a modal closes.

The Vimeo Player API (also called the Vimeo SDK) gives you a clean, promise-based interface to do all of that. And it's a lot simpler to set up than most people expect.

Here's how to get started.

What the Vimeo Player API Actually Does

When you drop a Vimeo iframe on a page, you get a video. That's it. You can't control it with JavaScript out of the box.

The Vimeo Player API changes that. It wraps your existing iframe in a JavaScript object and gives you methods to control playback, listen for events, and query the player's state. Think of it as a remote control for your embedded video.

It works by communicating with the iframe through the browser's postMessage API behind the scenes. You don't need to know how that works. You just need to know that it means there's a small initialization step before you can start issuing commands.

How to Load the SDK

The easiest way is to pull it in from Vimeo's CDN. Add this script tag before your closing </body> tag:

<script src="https://player.vimeo.com/api/player.js"></script>
```

If you're working in a JavaScript project with a bundler like Vite or webpack, you can install it via npm instead:
```
npm install @vimeo/player

For most Webflow projects, the CDN approach is the right call.

Setting Up Your Iframe

You can use an iframe you've already placed on the page. The SDK will attach to it. Give it an ID so you can target it easily:

<iframe
  id="my-video"
  src="https://player.vimeo.com/video/YOUR_VIDEO_ID?h=YOUR_HASH"
  frameborder="0"
  allow="autoplay; fullscreen; picture-in-picture; clipboard-write; encrypted-media"
  allowfullscreen>
</iframe>
```

If you want the video to autoplay, add `muted=1&autoplay=1` to the URL. Browsers block autoplay with sound by default, so muted is required for autoplay to work.
```
https://player.vimeo.com/video/YOUR_VIDEO_ID?h=YOUR_HASH&muted=1&autoplay=1

Creating a Player Instance

Once the SDK is loaded and your iframe is on the page, you create a player instance by passing the iframe element to Vimeo.Player:

const iframe = document.getElementById('my-video');
const player = new Vimeo.Player(iframe);

That's it. You now have a player object you can control with JavaScript.

The Methods You'll Use Most

The API has a lot of methods, but these are the ones you'll reach for regularly.

Play and pause:

player.play();
player.pause();

Reset the video back to the start:

player.setCurrentTime(0);

Unload the player entirely (stops playback and resets the video, great for modals):

player.unload();

Mute and unmute:

player.setMuted(true);
player.setMuted(false);

All of these return promises, which matters more than it might sound.

Why Promises Matter Here

Every method in the Vimeo Player API is asynchronous. That means when you call player.play(), it doesn't happen instantly. It sends a message to the iframe and waits for a response.

If you try to chain actions together without accounting for this, things break in ways that are hard to debug. Using .then() lets you wait for one action to complete before triggering the next:

player.pause().then(function() {
    // this runs after the video has actually paused
    doSomethingElse();
});

You should also handle errors with .catch() so your UI doesn't get stuck if something goes wrong:

player.unload().then(function() {
    modal.style.display = 'none';
}).catch(function() {
    modal.style.display = 'none';
});

In both cases above the modal closes, whether the unload succeeded or not. That's intentional. You want your UI to keep working even if the API hits an issue.

Waiting for the Player to Be Ready

This is the part that trips people up most often. The SDK needs time to establish a connection with the iframe before it can accept commands. If you call player.play() immediately after creating the player instance, it might silently fail.

The fix is player.ready(), which returns a promise that resolves once the connection is established:

player.ready().then(function() {
    player.play();
});

You don't need to wrap every single method call in ready(). Once the player is initialized, subsequent calls work fine. But for anything you want to fire right away on page load or on a timed trigger, wrapping it in ready() is the safe move.

Listening for Events

The API also lets you respond to what the player is doing. Some useful events:

// fires when the video starts playing
player.on('play', function() {
    console.log('playing');
});

// fires when the video pauses
player.on('pause', function() {
    console.log('paused');
});

// fires when the video ends
player.on('ended', function() {
    console.log('ended');
});

This is useful when you want to trigger something else on your page based on what the video is doing, like showing a CTA after the video ends, or tracking engagement.

A Note on Multiple Players

If you have more than one Vimeo video on the same page, each iframe needs a unique ID. When you create player instances, make sure each one is targeting the right element:

const popupPlayer = new Vimeo.Player(document.getElementById('video-popup'));
const heroPlayer  = new Vimeo.Player(document.getElementById('video-hero'));

Mixing these up is a common source of confusion. You'll call pause() on what you think is one video and something completely different stops playing. Unique, descriptive IDs save a lot of debugging time.

Putting It All Together

Here's a simple example that plays a video when a button is clicked and pauses it when another button is clicked:

const iframe = document.getElementById('my-video');
const player = new Vimeo.Player(iframe);

document.getElementById('play-btn').addEventListener('click', function() {
    player.ready().then(function() {
        player.play();
    });
});

document.getElementById('pause-btn').addEventListener('click', function() {
    player.pause();
});

Clean, readable, and it handles the initialization timing correctly.

The Vimeo Player API Is Worth Learning

If you're building anything beyond a basic video embed, knowing how to control Vimeo with JavaScript opens up a lot of possibilities. Modal popups that autoplay and reset. Videos that pause when the user scrolls away. Custom controls that match your brand instead of the default Vimeo UI.

The SDK is well documented, actively maintained, and works reliably across modern browsers. Once you understand the promise-based pattern, the rest clicks quickly.
