Ecommerce API integration: connect your online store with your business systems
Ecommerce API integration lets the Shoppsy platform communicate directly with ERP systems, suppliers, warehouses and other business partners. Instead of moving product, price, stock and order data from one system to another by hand, an API for your ecommerce website lets systems exchange information and trigger processes on their own, with no extra work for your team.
No more manual data transfers with API integration for ecommerce
Every company uses a different mix of tools, suppliers and business processes. The problem starts when those systems don't talk to each other, and your employees become the link between them. A good API integration moves that link from people to technology.

Integration with the systems you already use
Whatever ERP, WMS, supplier or other business systems you use, we define how they communicate with the Shoppsy platform and automate the data exchange between them.
API integration methods: REST APIs, webhooks and custom connectors
There is no one-size-fits-all approach to API integration. Depending on the systems you use and the data you need to exchange, we choose the method that is the most reliable for your business:
REST API integration, when the connected system offers a documented ecommerce REST API
Webhooks, for instant notifications when an order, price or stock level changes
Middleware or integration platforms, when several systems need to share the same data
File-based exchange (XML, CSV) for suppliers and older systems without an API
Custom API integration and API development, when a system has no suitable interface
Every integration includes data validation, logging and error handling, so you always know what was exchanged and when.

What does the ecommerce API integration process look like?
1
System mapping
We map your systems, data sources and the points where communication needs to be established.
2
Defining the data
We decide what will be exchanged: products, prices, stock, orders, customers or other data.
3
Setting the rules
We define when data is sent, how often it is updated and which system is the source of each piece of information.
4
Building the connection
We connect the Shoppsy platform with the selected systems, and when a system doesn't have a suitable interface, we also develop the API.
5
Testing and launch
We check the data and test different scenarios, so the integration works reliably in everyday operations.
Connect your systems without complicated processes
From the first analysis to testing, we manage the entire integration, so data exchange between the Shoppsy platform and your systems runs reliably.
Your online store is only one part of the ecommerce process. Behind it are suppliers, ERP, warehouses, logistics, payments and many other systems that exchange information every day. When each of them works separately, the same information often has to be entered or checked in several places.
When they are connected through ecommerce APIs, information flows automatically and data reaches the system that needs it. This makes Shoppsy the central point of your ecommerce ecosystem, without having to replace your existing business systems.
When your online store becomes part of your business system
An online store doesn’t have to be an isolated sales platform. When it is connected with your ERP, suppliers, warehouses and other tools, it becomes part of a wider business system. Information created in one part of the business can be available in others, from purchasing and product management to sales and order fulfillment.
As an API-based ecommerce platform, Shoppsy adapts to your existing infrastructure and lets the API connect different systems, even when they weren’t originally designed to work together.

What does automated data exchange bring?
The value of an integration isn’t just the technical connection. You see it in everyday work: when a price change is transferred without anyone stepping in, when an order goes straight to the ERP or when stock levels are available wherever they are needed.
Frequently asked questions about ecommerce API integration
What is an ecommerce API?
An ecommerce API (Application Programming Interface) is an API for ecommerce websites: a set of rules that lets an online store and other software systems exchange data automatically. Ecommerce APIs are used to read and update products, prices, stock, customers, orders and payments without manual work. Whether it is your ecommerce platform API or the API of an external system, the role of an API in ecommerce is to keep all systems working with the same, up-to-date data.
What is API integration?
API integration uses an API to connect two or more systems so they share information automatically and manual work is kept to a minimum. In ecommerce, this can mean connecting your online store with an ERP, CRM, supplier, WMS, payment service or logistics system.
What are API integration services?
API integration services for ecommerce platforms cover the planning, development, testing and maintenance of the connections between your online store and the systems around it. With Shoppsy, ecommerce API integration services include system mapping, data rules, development of the connection, testing and ongoing support.
What are ecommerce integrations?
Ecommerce integrations are connections between your online store and other tools and systems your business relies on, such as ERP, CRM, warehouse management, suppliers, payment gateways, couriers and marketplaces. Most modern ecommerce integrations rely on an ecommerce integration API provided by one or both systems.
What data can be exchanged via API?
Depending on the specific integration, you can exchange data on products, prices, stock, customers, orders, payments and other business processes.
Which ecommerce APIs are essential for growth?
There is no single best ecommerce API, but for most growing online stores, the most important are the ERP API (products, prices, stock, orders and documents), payment and courier APIs, supplier APIs or feeds, and CRM or marketing APIs. Together they remove manual work and let you scale sales without growing your team at the same pace.
How do retailers use APIs for ecommerce and back-office integration?
Retailers use APIs to connect the online store with their back office: orders go automatically to the ERP and warehouse, stock and prices come back to the website, suppliers send updated catalogs, and payment and courier systems update order statuses. The result is one connected sales process across online and physical channels.
Can Shoppsy connect with my ERP system?
Yes, through a dedicated ERP integration tailored to the system you already use. You can find more details on the Shoppsy ecommerce ERP integration page.
Is it possible to connect several systems at once?
Yes. A single Shoppsy online store can communicate with several ERP, WMS, supplier, payment and logistics systems, depending on the architecture and needs of the project.
Can API integration automatically update products and stock?
Yes. If the connected system supports the right API communication, product, price and stock data can be pulled and updated in the Shoppsy platform automatically.
What happens if data exchange fails?
A well-designed integration plans for situations when something goes wrong. Data is validated before it is sent, and failed transfers are retried according to a predefined rule. Every exchange is logged, so error handling doesn't depend on a customer reporting a wrong price or stock level.
Should the integration be one-way or two-way, real-time or scheduled?
It depends on the process. Integrations can be one-way, for example only sending orders to the ERP, or two-way, when prices and stock are sent back to the online store. Data can be exchanged in near real time (for example via webhooks) or in scheduled batches, depending on how critical the data is and what the connected system supports.
When should you use middleware vs custom API integration?
Middleware or an integration platform makes sense when several systems need to share the same data and standard connectors already exist. Custom API integration is the better choice when your processes, pricing rules or systems are specific, or when a system has no ready-made connector. We often combine both approaches.
Is ecommerce API integration secure?
Yes, when it is set up correctly. We use secure, authenticated connections, limit access to only the data each system needs, and log every exchange. This protects your business and customer data while keeping the integration transparent.
How long does it take to build an API integration?
The timeline depends on the number of systems, the amount of data, the available API documentation and the complexity of business rules. Before development starts, we define the systems, data and processes the integration needs to cover.
How much does an ecommerce API integration cost?
The cost depends on the number of systems, the integration method, the quality of the available API documentation and the complexity of your business rules. After the initial analysis, we prepare a project estimate tailored to your needs.
How do you choose an ecommerce API integration provider?
Look for a provider with proven experience in ecommerce, not just general software integrations. They should understand ERP, warehouse and supplier processes, offer monitoring and support after launch, and be able to show real projects. It also helps if the same team manages your ecommerce platform, so integrations and the online store develop together.
