Woocommerce Abandoned Cart API: How to Implement It in Your Software in 2025​

Abandoned carts are a significant challenge for eCommerce businesses, leading to lost revenue and decreased conversion rates. To help merchants recover these lost sales, WooCommerce provides the Abandoned Cart API, allowing software developers and service providers to integrate automated solutions for customer retention.

With this API, developers can track abandoned carts, retrieve product and customer data, and launch email campaigns, push notifications, or special discount offers to encourage customers to complete their purchases. This functionality is particularly valuable for CRM systems, marketing automation platforms, eCommerce SaaS solutions, and loyalty programs.

In this article, we’ll explore the capabilities of WooCommerce Abandoned Cart API, how to integrate it, and how software providers can leverage it to enhance their eCommerce solutions.

Key Features of WooCommerce API

The WooCommerce API is a powerful tool that enables software developers and service providers to integrate their solutions with WooCommerce stores. It facilitates business process automation, data exchange, and eCommerce platform expansion, including integration with CRM, ERP, and marketing tools. However, there are some essential features to keep in mind when working with this API:

1. RESTful API with Extensive Functionality

WooCommerce API follows a RESTful architecture and supports CRUD operations (Create, Read, Update, Delete) via HTTP requests (GET, POST, PUT, DELETE). It responds in JSON format, which helps to integrate with external services and allows you to work with:

• Products and categories;
• Orders and transactions;
• Customers and user roles;
• Coupons and discounts;
• Shipping and tax settings.


2. Authentication and Security

WooCommerce API supports multiple authentication methods:

• OAuth 1.0 – Secure but complex to implement;
• Basic Authentication – Uses API keys but requires HTTPS;
• JWT Authentication – Uses token-based authentication for secure access.

Developers must ensure proper security measures to prevent unauthorized access to store data.

3. Flexibility and Customization

One of WooCommerce API’s biggest strengths is its flexibility and customization options:

• Adding new endpoints using WordPress hooks;
• Modifying API responses to fit business logic;
• Creating custom plugins to extend WooCommerce functionality.

This makes WooCommerce API an ideal choice for SaaS providers looking to deliver customized solutions for eCommerce businesses.

4. No Strict API Rate Limits

Unlike many other eCommerce APIs, WooCommerce does not impose strict request limits. However, for better performance, developers should:

• Use pagination when handling large datasets;
• Editing API responses regarding business logic;
• Optimize API requests to prevent unnecessary processing.

This is particularly important for large-scale WooCommerce stores with thousands of products and orders.

This type of API is a very flexible and powerful tool for developers and SaaS providers that allows you to integrate WooCommerce stores with other services. Its flexibility, support for webhooks, and customization options make it ideal for advanced eCommerce solutions. However, developers have to deal with authentication, performance, multi-store integration, and functionality limitations.

Implementation of the WooCommerce Abandoned Cart API

Using the WooCommerce Abandoned Cart API helps reduce abandoned carts, optimize your marketing campaign, and increase conversion rates. You can implement this API method using two main approaches: creating the integration yourself or using a third-party service.

Developing an Integration In-House

Internal integration with this kind of API can provide full control over abandoned cart data collection and processing processes. However, this approach has several drawbacks that can affect the cost, efficiency, and support of the integration:

• Long development period – Implementation of a custom solution requires time, resources and technical knowledge;
• Need for constant updates – WooCommerce continues to release updates that may change the database structure or API, requiring developers to adapt the integration;
• Additional testing costs – Integration requires very detailed testing to prevent performance, security and compatibility issues;
• Lack of official support – This eCommerce platform is open-source, so developers must solve technical problems on their own;
• Insufficient documentation – This API method lacks detailed documentation for abandoned carts, making integration more difficult.

Using API2Cart for integration

API2Cart is a service and powerful solution that provides an API to integrate WooCommerce and 40+ other eCommerce platforms, including Shopify, Magento, BigCommerce, OpenCart, PrestaShop, and others, at once, through a single API.

You can use API2Cart to retrieve data about abandoned carts and automate the recovery process, instead of developing your own integration with the WooCommerce Abandoned Cart API. The integration does not require complex coding and API changes every time WooCommerce is updated.
