Cardflo offers a Shopware payments plugin designed to integrate advanced payment orchestration into your Shopware store. This plugin provides secure, efficient transaction processing, smart routing capabilities, and support for a wide range of payment methods.
Merchants can enhance their Shopware checkout experience and optimise payment flows.
The Shopware plugin accelerates merchant onboarding and integrates diverse APMs alongside multi-acquirer partners. This enables real-time data monitoring and boosts checkout conversion, while ensuring faster transactions for your customers.
Shopware payments plugin overview
Shopware 6 merchants often require payment infrastructure that extends beyond a single acquirer connection. A dedicated payment plugin for this e-commerce platform facilitates an integration between the store front-end and a backend payment orchestration layer.
By deploying a plugin rather than a manual API integration, retailers can standardise the collection of sensitive cardholder data through secure iframes or hosted fields, maintaining PCI DSS compliance. The architecture allows the merchant to configure multiple payment service providers and alternative payment methods within the Shopware administration panel.
This centralisation helps manage complex transaction flows, including multi-currency settlement and automated reconciliation, while ensuring that the checkout process remains responsive. Integrating at this level ensures that the business can adjust its payment logic, such as smart routing or failover mechanisms, without modifying the underlying PHP framework or database schema of the Shopware installation.
How shopware payments plugin works
Plugin installation and configuration
The merchant installs the plugin zip file or via Composer in the Shopware 6 environment. Initial configuration involves entering API credentials and secret keys to establish a secure handshake between the store and the payment gateway. This process registers the merchant identity and synchronises supported currencies and basic transaction settings.
Payment method mapping
Within the Shopware admin, the merchant activates specific payment methods such as credit cards, SEPA, or digital wallets. These are mapped to specific sales channels, allowing for localised payment options based on the customer country or currency, which is critical for international B2B and B2C operations.
Checkout authorisation flow
When a customer initiates a transaction, the plugin handles the communication with the PSP. For card payments, it manages the 3DS authentication process and collects the authorisation code from the issuer. The plugin then updates the Shopware order status from 'open' to 'authorised' or 'paid' in real time.
Post-authorisation management
The plugin facilitates backend operations directly from the Shopware order overview. Merchants can trigger capture requests for delayed settlement or initiate partial and full refunds. This bidirectional sync ensures that the payment status in the gateway always matches the order status in the e-commerce database.
Why shopware payments plugin matters
Reduced Development Overheads
Developing a custom payment bridge for Shopware requires significant engineering resources to maintain security protocols and API versioning. Using a pre-built plugin ensures that the business can utilise standard hooks within the Shopware ecosystem, reducing the time required to go live. Maintenance and updates for new security standards, such as PSD2 or updated 3DS versions, are typically handled by the plugin provider, allowing the merchant to focus on core operations.
Optimised Conversion Rates
Checkout friction is a primary cause of cart abandonment in the Shopware environment. A robust plugin supports features like account updater services and network tokenisation, which help minimise declines for returning customers. By offering a variety of alternative payment methods and ensuring the payment interface is responsive and localised, merchants can better address regional consumer preferences, which directly impacts the successful completion of the authorisation process.
Shopware payments plugin use cases
European cross-border Shopware retailers
Shopware 6 merchants use Rule Builder conditions to vary checkout methods by sales channel, shipping country, currency or basket contents without maintaining separate storefront code. Cardflo configures the plugin to translate eligible conditions into payment-method availability and routes resulting card transactions through suitable acquirer partners.
Shopware storefront payment redirects
European Shopware stores offering iDEAL and other redirect-based methods must preserve cart, order and payment states when shoppers leave the storefront and return. Cardflo’s plugin manages redirect callbacks, transaction references and status updates so finance teams can reconcile completed, cancelled and abandoned payment attempts against Shopware orders.
Multi-store plugin configuration
Operators running several Shopware 6 sales channels need distinct currencies, payment methods and MID mappings while retaining one administration environment. Cardflo supports sales-channel-level plugin configuration and multi-acquirer routing, allowing each storefront to apply its approved acquirer setup without duplicating catalogue or checkout development.

Questions about Shopware payments plugin
How does the Shopware plugin handle Strong Customer Authentication (SCA)?
The plugin is designed to comply with PSD2 requirements by facilitating the 3D Secure 2. x protocol. During the checkout process, the plugin communicates with the issuer to determine if a challenge is required.
If necessary, it handles the redirect or modal window where the customer validates their identity. This reduces the risk of soft declines by ensures that the required authentication data is passed correctly to the acquirer throughout the authorisation flow.
Can I use the plugin to manage refunds for partial shipments?
Yes, the plugin supports partial capture and partial refund functionality within the Shopware order management interface. If a merchant is unable to fulfil a complete order, they can capture only the amount corresponding to the shipped goods.
Similarly, if a customer returns a single item from a multi-item order, the merchant can trigger a partial refund to the original payment method, which the plugin then communicates to the acquirer.
Does the plugin store credit card data on the Shopware server?
No, to maintain PCI DSS compliance, the plugin typically uses secure iframes or hosted fields. This means that sensitive cardholder data flows directly from the customer's browser to the payment processor's secure vault.
Only a non-sensitive token is stored within the Shopware environment. This architecture significantly reduces the compliance burden on the merchant as they never actually touch or store the raw card data.
How does the Shopware payment plugin use Rule Builder conditions?
The Shopware 6 plugin can use Rule Builder conditions to control which payment methods appear for an order.
E-commerce teams can configure availability by criteria such as sales channel, billing or shipping country, currency, customer group and order value, subject to the enabled method and acquirer partner setup.
This allows each storefront to present relevant card, wallet and local European payment options without maintaining separate checkout integrations.
Is it possible to use multiple acquirers with the Shopware plugin?
Yes, the plugin acts as a gateway to a payment orchestration layer where multiple acquirer connections can be configured. This allows the merchant to implement smart routing rules.
For example, transactions from a specific country can be sent to a local acquirer to minimise scheme fees and improve the likelihood of authorisation, while other transactions are routed through a different provider.
How are alternative payment methods (APMs) configured?
Alternative payment methods such as iDEAL, Bancontact, or various 'Buy Now Pay Later' options are managed within the payment method settings of the plugin. Once enabled and configured with the relevant PSP credentials, these methods appear as options in the Shopware checkout.
The plugin manages the specific redirect logic and lifecycle for each APM to ensure consistent order tracking.

A merchant acquirer is a licensed bank that holds your account, takes liability for transactions, and settles funds. The payment processor is the technology layer routing data between the checkout, card networks, and issuing banks. Every card payment requires both components to manage technical encryption and financial liability. They are often separate entities with distinct fee structures.

The payment gateway acts as the technological bridge, encrypting sensitive data between the website and the acquirer. Merchants need both components to ensure that electronic payments are accepted, authorised, and settled. Together, they create a seamless and secure payment experience for customers.
