Cart REST API for WooCommerce – CoCart Lite


CoCart: The #1 REST API that handles the frontend of WooCommerce.

CoCart handles the shopping cart in any modern framework of your choosing. No local storing required. Powerful and developer friendly ready to build your headless store, without building an API.

Why should I use CoCart?

The question is why not! WooCommerce’s REST API is only created for store managers to control the backend of your store. So it’s not the API you need to allow your customers to shop.

If you are wanting to build a headless WooCommerce store then CoCart is your solution.

With the documentation provided, you’ll learn how to enable the ability to add products to a cart and allow your customers to manage it in no time.

Testimonials – Developers love it

CoCart, in my opinion, is the best frontend REST API for WooCommerce. Don’t just take my word for it though:

This plugin saved me tones of work and it is working amazingly! The plugin author provides fast and high quality support. Well done! @codenroll

Thanks for doing such a great work with this! Works exactly as expected and CoCart seems to have a nice community around it.

  • Empty Cart
  • Cart with Item


Minimum Requirements

  • WordPress v5.3
  • WooCommerce v4.3
  • PHP v7.0

Automatic installation

Automatic installation is the easiest option as WordPress handles the file transfers itself and you don’t need to leave your web browser. To do an automatic install of CoCart, log in to your WordPress dashboard, navigate to the Plugins menu and click Add New.

In the search field type “CoCart” and click Search Plugins. Once you’ve found the plugin you can view details about it such as the point release, rating and description. Most importantly of course, you can install it by simply clicking “Install Now”.

Manual installation

The manual installation method involves downloading the plugin and uploading it to your webserver via your favourite FTP application. The WordPress codex contains instructions on how to do this here.


Automatic updates should work like a charm; as always though, ensure you backup your site just in case.


Is CoCart free?

Yes! CoCart’s core features are absolutely free. CoCart Pro completes the full cart experience!

How do I start using CoCart?

You will first need WooCommerce v4.3 or higher installed with the REST API enabled. Then install CoCart and follow the documentation. That’s it!

Why should I use CoCart?

The question is why not! WooCommerce’s REST API is only created for controlling the backend of your store. Not the API your needing for your customers who only see the frontend.

If you are wanting to build a headless WooCommerce store then CoCart is your solution.

Who should use CoCart?

CoCart is perfect for store owners and developers. If you want to create an e-commerce app for mobile or a custom frontend shopping experience completely using the REST API, then you need to use CoCart.

Do I need to have coding skills to use CoCart?

As this plugin is built for developers, you will need to have some coding knowledge to use it. Checkout the documentation to get some understanding.

Where can I find documentation for CoCart?

You can find the documentation for CoCart on the CoCart REST API Docs.

Can I change the layout format/add/change details to the responses?

You certainly can. Filters are available to do just that. Checkout the tweaks plugin to view or maybe use the examples provided. View the documentation for more.

Is it compatible with WooCommerce Shipping and Tax plugin?

Not at this time. WooCommerce Shipping and Tax ignore any REST API from allowing the ability to calculate the taxes from TaxJar. Code has been contributed to the plugin that will allow third-party plugins enable this ability and awaiting feedback.

Why CoCart and not WooCommerce Store API?

WooCommerce Store API is not yet complete and stable in order to publish the first release of their API for public use. It is also limited for developers to use on many levels such as the body type the API can be requested in and support for guest customers which CoCart does have.

Their API is designed mainly to focus on their Gutenberg blocks they have developed while CoCart is designed to focus on supporting many frameworks and languages outside of WordPress to allow your store to be headless.

CoCart is also backed by a community to make the REST API better for all developers.

Do you have a JavaScript Library?

Yes we do. You can find it here. It’s very similar to WooCommerce’s JavaScript Library. The only difference is that it’s much up to date and doesn’t require authentication so guest customers can be supported. It supports CommonJS (CJS) and ECMAScript Modules (ESM). Requests are made with Axios library with support to promises.

Can I install/update CoCart via Composer?

Yes. The best method would be to install/update CoCart from the GitHub repository but you can also do so via

Does CoCart work for multi-site network?

Yes. Just install CoCart and activate it via the network and all sites will have CoCart enabled.

Can I enable white labelling for CoCart?

Yes you can. You will have to edit your wp-config.php file to add a new constant. Details can be found in the documentation.

Does CoCart work with the Dokan plugin?

Yes. The only feature you wont be able to use are coupons if you have CoCart Pro. This is because Dokan disables the use of coupons in WooCommerce. All other features are compatible.

Where can I report bugs?

Report bugs on the CoCart GitHub repository. You can also notify us via the support forum – be sure to search the forums to confirm that the error has not already been reported.

CoCart is awesome! Can I contribute?

Yes, you can! Join in on our GitHub repository and follow the development blog to stay up-to-date with everything happening in the project.

Is CoCart translatable?

Yes! CoCart is deployed with full translation and localization support via the ‘cart-rest-api-for-woocommerce’ text-domain.

Where can I get help or talk other users about CoCart core?

If you get stuck, you can ask for help in the CoCart support forum or join the CoCart Community on Slack where you will find like minded developers who help each other out. If you are in need of priority support, it will be provided by either purchasing CoCart Pro or the 14 day priority support.

Where can I find out about the pricing of CoCart Pro?

Find out all relevant pricing information over on the official site.

🔥 This is a HOTFIX!

  • Fixed: Merge guest customers cart with a registered customers cart once authenticated.
  • Dev: Triggers saved cart after authentication and updates user activity.
