Systems that don't talk to each other. That's not a technical problem. It's a decision.
Every modern system has an API. Those who do not use them are sticking notes between machines. We build the connections that make your systems work as a team.
CSV export, manual import, errors, repeat.
Every morning someone exports a file from system A and imports it into system B. Maybe it even runs automatically, with a script from 2018 that nobody wants to touch. Sometimes it works. Sometimes it doesn't. And when it doesn't, someone notices three days later.
Almost all modern cloud and SaaS tools have open APIs. Systems that don't have one probably shouldn't exist anymore. An API is the way systems communicate with each other today, in real time, reliably, without manual intervention.
What CSV files and night scripts used to handle is now solved by a properly built interface. Faster, more stable, and without anyone having to check first thing Monday whether the import ran.
Not every API is the same. Here is what you need to know.
REST is the most common form. Separate endpoints for each object, easy to understand, widely used, well documented.
GraphQL goes a step further. A single endpoint per object, but flexible in what gets queried. Fewer requests, more control over the data that comes back.
SOAP is the older standard, still found mainly in enterprise environments. More verbose, but robust and good for complex transactions.
And then there are systems that have no API interfaces out of the box. There are ways around this too, as connectors exist for every database and all common programming languages. No system is an island if you know how to open it.
Three forms of interfaces we implement every day.
Three forms of interfaces we implement every day.
Direct system-to-system interfaces
CRM talks to ERP. Shop system talks to inventory. Accounting gets data straight from the source. No manual work, no delays, no errors from copy-paste.
The result: Data that is always current, in every system.
Middleware APIs
In more complex environments a central middleware makes sense. Instead of addressing each service individually, the middleware handles coordination. One request, multiple systems respond in the background. Logic is mapped centrally, not scattered.
The result: Fewer dependencies, more control, easier maintenance.
APIs for systems without an API
Not every system comes with an open interface. For legacy systems, older databases or proprietary software we build connectors that enable data access from the outside.
The result: No system stays an island.
Clean interfaces are not an IT task. They are the foundation for everything that comes after.
Automations need reliable data. AI projects need clean data foundations. Reporting needs a single source of truth. All of that only works when the systems in the background talk to each other stably.
We work with API interfaces every day, regardless of which systems, regardless of which industry. We develop custom interfaces, build middleware solutions and make sure data arrives where it is needed. Without manual work. Without error-prone workarounds. And without anyone having to check the import first thing Monday morning.
Three systems. One truth. No more manual exports.
A company runs a shop system, an ERP and a CRM. Customer data is manually synchronised between all three systems, daily, by one person who spends two hours on it. Errors happen regularly.
We build a middleware that connects all three systems. Customer data is automatically synchronised whenever a change occurs in any of the systems.
- Daily manual effort reduced from 2 hours to 0
- Data errors from duplicate maintenance eliminated
- New customer in shop: immediately available in CRM and ERP
- Changes in ERP: immediately visible in all systems
- Middleware documents every data transfer, full traceability
Typical challenges regarding API interfaces
API Development: When the System Has No Interface
API development for systems without an interface: why missing APIs are not a dead end, how to build them and what that means for your data.
CSV Export Automation – Without Manual Work
CSV export: why export, edit and import is not a process, what goes wrong with encodings and delimiters, and how APIs solve this for good.
Data Silos: When Every System Has Its Own Truth.
Breaking down data silos: why marketing, sales and accounting all have different numbers, and what missing interfaces have to do with it.
ERP Interface Integration – Without the Big IT Project
Why the 'too risky' argument in ERP interfaces is usually wrong, which data should actually flow, and what a clean CRM-ERP integration delivers.
What you usually ask us about API interfaces.
In most cases yes. We work with the existing interfaces and databases without touching the core system. If that's not possible, we'll talk to the provider/partner and find the best solution.
No problem. For most databases and systems there are connectors or access methods we can use. No system is completely closed off.
We build it so your team can maintain it. Documentation, clear structure, no vendor lock-in. Knowledge stays in your house. If nobody can take over this on your side we will find a solution.
We can set up a simple, direct connection between two systems that already have APIs in a short amount of time (as little as one day). More complex middleware solutions take a bit longer, as they require more preparation. Let’s discuss the scope and we’ll give you an exact estimate of how long it will take.
YOUR SYSTEMS DON'T TALK TO EACH OTHER. WE CHANGE THAT.
Tell us briefly which systems need to be connected, we will tell you in one conversation what is possible.
