Custom Shopware integration development
Appfront builds custom Shopware 6 integrations that connect your online shop with your ERP, PIM, accounting, CRM or bespoke application. Using the Admin API, Store API and the app system with webhooks, we synchronise products, stock, orders and customers in real time and reliably. You keep your shop and back office in sync, avoid duplicate data entry and, if you wish, build a headless storefront on top of the Store API.
What is a Shopware integration?
Shopware 6 is an open e-commerce platform built on Symfony with an API-first architecture. It is available as a self-hosted installation and as Shopware Cloud, and is used by B2C and B2B webshops, D2C brands and retailers. The platform offers two central interfaces: the Admin API for system-to-system integrations and the Store API for customer-facing, headless applications.
In practice, a custom integration means synchronising products and stock from an ERP or PIM, passing orders on to your accounting or fulfilment system, exchanging customer data with a CRM, and responding in real time to events in the shop via webhooks. The Admin API provides CRUD operations on virtually every Shopware entity, while the Store API powers a custom frontend.
Appfront builds in line with the official Shopware developer documentation and the OWASP ASVS security standard. We tailor the integration layer, sync logic and error handling to your actual processes, so the integration grows with your range and remains reliable even at peak volumes.
Admin API & Store API
Two complementary interfaces: the Admin API for product, order and stock synchronisation between systems, and the Store API for a headless storefront. Together they form the foundation of almost every Shopware integration.
App system & webhooks
With the app system, you register webhooks that send a POST request in real time whenever something happens in the shop, such as an order, a stock change or a new customer. We validate the signature so your backend can respond immediately and securely.
Self-hosted or Shopware Cloud
Whether you self-host Shopware or run it on Shopware Cloud, we connect through the same standardised APIs. That keeps your integration portable and lets it evolve as your hosting or platform situation changes.
Our development process for Shopware integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your shop, range and adjacent systems through to go-live and ongoing management, every step is aimed at an integration your team can understand and trust.
We map out which entities you want to synchronise (products, stock, orders, customers), in which direction, at what frequency, and which systems (ERP, PIM, accounting or CRM) need to connect on the Shopware side.
We design the integration architecture, choose between the Admin API, Store API and webhooks, set up OAuth2 authentication and define an error-handling and retry strategy.
Implementation with automated tests, structured logging and monitoring. You see working builds along the way.
Controlled go-live with data validation and a safety net, followed by ongoing management and further development.
What a Shopware integration delivers in practice
Every Shopware integration is set up specifically for your range, sales channels and adjacent systems. Below are the capabilities we most often deliver for organisations that use Shopware 6 as the core of their e-commerce.
Admin API & OAuth2
System-to-system integration via the Admin API with OAuth2 authentication (client credentials based on an integration with an access key and secret). CRUD operations on virtually every entity, so your back office and shop stay reliably in sync.
Store API & headless
Build a headless storefront on the Store API: a Vue.js, React or native frontend that queries products, categories, cart and checkout. The Store API is publicly accessible and only requires authentication for customer-specific endpoints.
Product & catalogue sync
Synchronise products, variants, categories, prices and media from an ERP or PIM into Shopware. Changes in your source flow controlled into the webshop, with field mapping and consistent keys per article.
Order sync to back office
Automatically pass new orders on to your accounting, fulfilment or ERP system, with order status feeding back to the shop. Via webhooks, your backend responds in real time to a placed or changed order, without manual re-keying.
App system & webhooks
Using the app system, you register webhooks for shop events. Shopware then sends a POST to your endpoint, accompanied by an HMAC signature that we validate against replay and tampering, so your integration only processes genuine, fresh events.
Customers & stock
Exchange customer data with your CRM and keep stock levels in step across channels in real time. A single central stock source prevents overselling, and customer data stays consistent across shop, CRM and back office.
Typical use cases in practice
A Shopware integration looks very different from one organisation to the next. We see a number of recurring patterns, and for each we have a working setup with attention to the right API choice, data mapping and sync frequency.
B2C webshops
Consumer-facing Shopware shops that draw their range, prices and stock from a central system and pass orders on to accounting or fulfilment. A single source of truth for products and stock prevents overselling. See also our API integrations and e-commerce development.
B2B webshops
Trade and wholesale businesses with customer-specific pricing, volume tiers and order history. The Admin API connects Shopware to the ERP for real-time stock and per-customer price lists, while orders flow back into the back office in a structured way.
D2C brands
Brands that sell directly to consumers and want a distinctive, often headless storefront. On the Store API we build a bespoke frontend in Vue.js or React, while stock, products and orders stay connected to the back office via the Admin API.
Retail & multichannel
Retailers who sell not only through their webshop but also via marketplaces, physical stores or a point-of-sale system. Webhooks keep stock levels in sync across all channels in real time, so a sale on one channel immediately updates availability on the others.
Technology we use
We build Shopware integrations with the official Admin API and Store API, the app system with webhooks and OAuth2 authentication, combined with the backend stack that suits you. The precise choice depends on your adjacent systems and hosting, so your own team can manage or further develop the implementation.
Why Appfront for your Shopware integration?
Appfront has extensive experience building API integrations for a wide range of organisations in the Netherlands. We always start with a thorough analysis of your existing systems and processes. An integration should not only work technically, but also add practical value to the way you work.
For every integration, we write clear documentation and make sure your own team, or any future supplier, can understand and manage it. No black box, just transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical and the functional side. This keeps communication short, prevents misunderstandings and speeds up decisions when choices need to be made during development.

Security and privacy in Shopware integrations
A Shopware integration processes customer and order data, plus business-sensitive data such as prices and stock levels. Appfront builds to the OWASP ASVS. That means, among other things: OAuth2 credentials held in secure vaults, scoped permissions per integration, validation of the webhook signature against replay attacks, and regular audits of the data flows.
Authentication to the Admin API runs via OAuth2 with an access key and secret, and we keep scopes as narrow as possible for each integration. We document the data flows between Shopware and your surrounding systems so that your record of processing activities is complete and you can demonstrably comply with the GDPR. We validate webhook payloads for signature and timestamp, so that only genuine and recent events are processed.
More on our security approach: information security policy and CVD policy.
- GDPR-compliant data processing and data minimisation
- Encryption in transit (TLS 1.2+) and at rest
- Role-based access and least-privilege principles
- Audit logs with traceable data flows
- Automatic retries and dead-letter queues
- Monitoring and alerting for anomalies
- Secrets management in line with best practice
- Documentation for your record of processing activities
Frequently asked questions about Shopware integrations
Answers to the questions we are asked most often about Shopware 6 integrations.
A Shopware integration is a technical link between your Shopware 6 online shop and another system, such as your ERP, PIM, accounting package, CRM or a bespoke application. Through the Admin API, products, stock, orders and customers are read and written programmatically; through the Store API, you can build a headless storefront that requests customer-facing data. The app system with webhooks pushes real-time updates whenever something changes in the shop. An integration can be simple (synchronising stock from a single source) or extensive (full order, product and customer sync across several systems).
Shopware 6 suits B2C and B2B webshops, D2C brands and retailers who want a flexible, Symfony-based e-commerce platform with an API-first architecture. It is particularly strong when you need bespoke functionality, serve multiple sales channels or want to build a headless storefront on the Store API. Shopware is available as a self-hosted installation and as Shopware Cloud. For very simple shops with no integration requirements, a lighter platform may be more appropriate; we are happy to discuss this with you.
For system-to-system integrations we use the Admin API, which provides CRUD operations on virtually every Shopware entity and authenticates via OAuth2 (client credentials based on an integration with an access key and secret). For customer-facing, headless applications we deploy the Store API. To respond to events in real time, we register webhooks through the app system and validate their signatures. We build the backend in the language that suits you best: PHP, Node.js, Python or .NET.
We work with the official Shopware 6 Admin API and Store API, the app system with webhooks, and OAuth2 for authentication. Shopware itself runs on Symfony (PHP). We build our integration layer in the stack that suits you — PHP, Node.js, Python or .NET — with message queues for asynchronous sync, structured logging and monitoring. For headless storefronts, we work with frameworks such as Vue.js or React on top of the Store API.
The cost depends on the complexity of the data flows, the number of systems to connect, the required sync frequency and the amount of custom business logic. Whether you self-host or use Shopware Cloud, and the need for ongoing maintenance, monitoring and support, also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation.
Yes. Shopware integrations process personal data (customers, orders) and commercially sensitive data (prices, stock), so security is central. Appfront builds in line with the OWASP ASVS: OAuth2 credentials stored in secure vaults, permissions scoped per integration, validation of webhook signatures and strictly separated rights. We document the data flows so that your record of processing activities remains complete and you can demonstrably comply with the GDPR.
Yes. Appfront regularly takes over existing Shopware integrations, even if they were originally set up by another party. We review the Admin API and Store API connections, the app and webhook configuration and the error handling, document the current setup and propose improvements. From that point on, we handle adjustments, extensions and monitoring, including timely rotation of OAuth2 credentials.
Shopware 6 is a good fit for B2C webshops, B2B trading companies, D2C brands and retailers with multiple sales channels. Typical use cases include synchronising stock and products from an ERP or PIM, passing orders on to accounting or fulfilment, building a headless storefront on the Store API, and responding to shop events in real time via webhooks. For organisations with strong integration or custom development needs, Shopware's API-first nature really comes into its own.
