Shopware is one of the most popular open-source eCommerce platforms in Europe, developed by the German company Shopware AG. The company creates omnichannel solutions used by European leaders in B2B and B2C commerce. This software is used by over 100,000 stores, also from the Enterprise segment.

Shopware eCommerce platform is software that consistently follows the API-First approach. Compared to other systems, Shopware 6 has the advantage to control all store functions via API.

Shopware API interfaces enable integration with other systems such as ERP, CRM, and PIM, for integration with marketplaces, shipping and payment providers, it also enables safe sharing of the store platform to connect devices with customers and for sales in various sales channels.

Shopware API

With Shopware 6, you get a powerful API for integrating third-party systems into your eCommerce processes. However, establishing proper communication requires external applications to authenticate through individual security keys. By default, Shopware 6 lets you create those individual keys right within the system. Consequently, you get the ability to track changes associated with external apps.

Shopware 6 offers two HTTP-based REST APIs, each with its own individual use: Store API and Admin API.

Frontend-facing interactions – Store API

The Store API provides endpoints for all customer interactions like:

  • Searching products
  • Creating carts
  • Placing and viewing orders
  • Making payments
  • Managing wishlists

It is protected using an access key that can be shared with end-clients and a context key that must only be shared with one client.

Applications using the Store API:

  • shopware-pwa – a storefront PWA framework for Shopware 6 using Vue.js and Nuxt.js based on the Vue Storefront project (good solution e.g. for Shopware for fashion eCommerce)

Documentation: Shopware Store API

Backend-facing interactions – Admin API

The Admin API should be the one used to create integrations with third-party systems. It may be used for:

  • Synchronization
  • Automation
  • Integration

It is protected using backend credentials that cannot be shared with end-clients.

Applications using the Admin API:

  • Shopware Admin Panel

How to integrate Shopware with external platforms (external software)

This ready-for-integration platform lets you seamlessly connect applications using API access.

With Shopware 6 API you are able to connect applications to Shopware. To create API access, you should be logged in to your Shopware account and go to Settings > System > Integrations, then click on Create integration.
The next steps involve:

  1. Assigning a name to the integration
  2. Setting the permissions (whether the integration should have the permissions of the administrator)
  3. Setting the role (if there is any created)
  4. Receiving Access key ID and Secret access key

The security key should be saved in a safe place.

To manage the integration, you may click on the name of integration and then you can edit it. The integration may be also deleted. Remember, that after changing the integration details, you should regenerate both the Security key and the Access ID by clicking on the „Regenerate API access key.”

Differences between applications and plugins

Apps and plugins are collectively known as extensions in the Shopware ecosystem, but they differ from each other.


Apps permit you to register an external URL endpoint with a Shopware system to exchange API credentials and register webhooks that Shopware calls when something happens in a Shopware system.

Apps permit you to build an independent system within Shopware that will interact with the whole eCommerce ecosystem. Which is worth noting though apps will not allow PHP code execution relevant to a Shopware system. For that, you may need to use Shopware plugins.

How to create an app

To create Shopware integration like apps, read official Shopware documentation.


The main way to extend your Shopware 6 instance programmatically is by creating a plugin.

Plugins in Shopware are essentially an extension of Symfony bundles. Those plugins and bundles may provide their own resources e.g. controllers, assets, services or tests.  

A plugin is the main way to extend your Shopware 6 instance programmatically.

You can integrate plugins into Shopware and perform almost everything with them.
