API Development & Integration Services
Secure REST APIs and integrations that connect your store, CRM, ERP, and third-party services and automate data exchange.
Web Development Scalable Secure Performance Reliable Long-Term Support
Web Development
We build the APIs and integrations that keep a company's systems telling the same story - the website, the store, the ERP, the CRM, the accounting package, the carriers, and whatever internal application everything else has to agree with.
That means custom REST APIs where you need to expose your own functionality, and middleware where two systems cannot talk to each other directly.
When custom integration work is the right call
If a supported connector exists and it fits, use it. Custom integration is worth paying for when the data does not survive the trip, or when nobody owns what happens the day it fails.
Worth doing
The cases where custom integration pays for itself:
The same information is entered into two systems by hand, every day- Ready-made connectors exist but drop, flatten or mis-map the fields your business actually runs on
- Two systems use different data structures or business rules and need middleware to translate between them
- You need to expose your own functionality to a partner, an app or another platform through a documented API
- A legacy application has to reach modern cloud services without being replaced
- The current integration works until it does not, and nobody finds out before a customer does
Not a fit
We will say so if you land here:
- A supported connector already does the job properly
- The source system has no API, no export and no database access - there is nothing to integrate with
- The data itself is unreliable; an integration only spreads the problem faster
What you get
- Custom REST APIs with a clear endpoint structure, versioning, consistent formats, and documentation your own developers can work from
- Middleware that transforms formats, maps entities, validates incoming data and handles the exceptions
- Synchronization that fits the process: real-time, event-driven, queued, scheduled, or batch import and export
- Security built in - OAuth 2.0 or JWT authentication, API keys, role-based access, HTTPS, input validation, rate limiting, audit logging and safe error handling
- Error handling, logging and monitoring, so a failed run is visible and can be re-run instead of passing silently
- Automated tests covering both the individual endpoints and the end-to-end business scenario
- The repository, the hosting and the service accounts - in your name, documented
What we connect it to
The systems differ from client to client; the data rarely does. Typical work keeps products and prices, stock levels, customer accounts, orders, shipments, invoices and payments in step - between ERP, CRM, PIM and warehouse systems, online stores, accounting software, payment providers, shipping carriers, marketing platforms and third-party SaaS services, as well as internal applications over their own APIs.
How we build it
- We start from the business process, not the endpoint list - what has to be true in both systems, and when
- Data models, endpoints, authentication, error handling and synchronization method are designed before implementation begins
- Built in .NET, a stack we know deeply, so the integration stays maintainable long after launch
- Tested for the failure cases as well as the happy path, because integrations fail at the edges
- Deployed with monitoring and error tracking, so problems surface before your customers find them
- Maintained as the systems on either end change their own APIs
Frequently Asked Questions About API Development & Integrations
Can you integrate with our existing software?
In most cases, yes. We work with modern APIs and with legacy systems, provided there is some workable method of exchanging data. We look at your environment first and recommend the approach that fits it.
Do you only develop REST APIs?
REST is the most common choice for business applications, but a project may involve other communication methods depending on the systems at either end. We pick the one the systems can actually support.
Can you integrate multiple systems in one project?
Yes. Many projects connect several platforms at once - an ERP, a CRM, a store, accounting software, logistics providers - through one integration architecture rather than a pile of separate scripts.
How do you secure API integrations?
Measures depend on the systems involved but commonly include encrypted communication, authentication, authorization, access controls, input validation, rate limiting, logging and secure error handling.
Can existing integrations be improved?
Yes. We regularly take over existing APIs and integrations to improve their performance, reliability, maintainability, security and compatibility with newer systems.
Who owns the code, and do you support it afterwards?
You do - the code, the repository, the hosting and the service accounts. Emporica continues with maintenance, monitoring and enhancements as your systems evolve, but you are never dependent on us to keep the integration running.
