Move products, stock and orders between OpenCart and the systems your business relies on. We design API connections and custom workflows around clear data rules, practical testing and a plan for failures.
Illustrative data flow. Direction, timing and ownership are defined for each project.
Less copying. More control.
01
Reduce repetitive entry
Agree which information should move automatically instead of re-entering it in several systems.
02
Keep the rules consistent
Define product identifiers, stock ownership, price rules and order statuses before connecting systems.
03
Make exceptions visible
Plan how staff can recognise failed exchanges and what happens when a request needs attention.
THE CONNECTIONS YOUR BUSINESS NEEDS
What would you like to connect?
These are workflows we can assess and build around. Feasibility depends on API access, documentation, licences and the capabilities of each system.
System or workflow
Typical information
What we define first
ERP and inventory
Products, stock, orders and status changes
Which system owns each field and how updates are matched.
Accounting
Order, customer and invoice-related data
Required fields, tax mapping and how corrections are handled.
Suppliers and dropshipping
Catalogues, availability, prices and order transfers
Feed quality, identifiers, update frequency and fulfilment rules.
Shipping and fulfilment
Delivery services, shipment data and tracking updates
Supported carrier APIs and the steps your team needs.
Marketplaces and business tools
Listings, orders and operational data
Channel requirements, permissions and API limits.
REAL INTEGRATION WORK
InPost: connecting OpenCart with parcel delivery.
OCS developed the official OpenCart module in direct cooperation with InPost. The project includes integration with the InPost API and Parcel Locker synchronisation.
These screenshots show delivery settings and service management in the OpenCart administration. They illustrate this project, rather than a standard package included in every integration.
BUILT AROUND YOUR OPERATIONS
01
Start with the workflow, not the connector
A useful integration starts with a specific task: import a supplier catalogue, send paid orders to an ERP or exchange shipping information. We map the systems and agree the result before choosing how to build it.
Identify the source of truth for products, stock, prices and orders.
Map identifiers, required fields, currencies, taxes and status values.
Check API documentation, sample data, authentication and access permissions.
02
Choose the right timing for each exchange
Not every workflow needs an immediate API request. Scheduled feeds can suit catalogue updates, while supported webhooks or API calls may suit order events. We choose around your requirements and the external system.
Agree the update frequency and acceptable delay.
Account for pagination, API limits and timeouts.
Define how changes, cancellations and repeat requests are recognised.
03
Design for the requests that fail
The successful request is only part of the work. Missing fields, an unavailable service or a repeated callback should have a defined outcome. We agree the safeguards and recovery tools that belong in your project.
Validate incoming and outgoing data before processing.
Scope useful logs and error visibility without exposing credentials.
Define retry rules, duplicate protection and manual follow-up where needed.
04
Test the business journey and plan the handover
We test representative data and failure scenarios against the agreed scope. Launch planning covers access, deployment timing and any existing processes that need to change.
Use a sandbox or test environment where available.
Check normal transactions, invalid data and interrupted exchanges.
Agree documentation, responsibilities and maintenance when an external API changes.
From your requirements to a working connection
01
Discover
Share the systems, the task and the information that needs to move.
02
Define
Review API access, map the data and agree scope, cost and checks.
03
Build and test
Develop the agreed connection and verify normal and failure scenarios.
04
Launch and hand over
Deploy at an agreed time and explain operation, ownership and follow-up.
Can you connect my ERP, accounting system or supplier?+
We can assess it once we know the system and required workflow. API documentation, access, licensing and supported operations determine what is possible. We do not assume every system has a ready-made connector.
Can you improve an existing connector?+
Yes, we can review an existing integration and its code where access and licences allow it. We explain whether adapting it or building a new connection is the more practical approach.
Will stock and orders update in real time?+
Only where the systems and agreed design support it. We define update frequency, event handling and acceptable delays. Some workflows are better served by scheduled exchanges.
What happens if the API is unavailable?+
The scope should define timeouts, logs, retries and the way failed exchanges are brought to staff attention. Recovery and duplicate handling are designed around the workflow.
Can this work with Journal and multiple stores?+
We review your OpenCart version, extensions, custom code and store configuration first. Journal and multistore requirements are included where they affect the connection.
How much does a custom integration cost?+
The price depends on the systems, data mapping, business rules and testing needed. We agree the investigation or development scope and pricing before starting.
Who maintains it when an external API changes?+
We agree ownership and ongoing support during the project. Third-party API changes, new requirements and monitoring are not automatically included without an explicit maintenance agreement.
