Systems and API integration: let your data flow between your tools

Does each tool do its job — while your teams still act as the go-between?

We design system integrations and APIs that sync the right data, trigger the right actions, and make errors visible. You keep the tools that work while removing the exports, copy-paste, and double entry that slow your operations.

Public and private APIs, synchronisations, webhooks, legacy systems, and external platforms.

When your software does not communicate, your teams compensate

Information exists in the CRM but must be copied into the operational tool. A status changes on a platform but nobody is notified. Accounting receives an export it has to clean. A mobile app and a web portal apply different rules. A partner asks for data you still prepare by hand.

These workarounds create silos, delays, and conflicting versions of the same information.

A reliable integration answers simple but essential questions:

  • which system owns each piece of data?
  • when should information be transmitted?
  • what action should follow its creation or update?
  • what happens if the destination system does not respond?
  • how do you avoid duplicates?
  • how do you find and fix a failed exchange?

Our work is not only making two APIs talk. We build an exchange your business can use and supervise over time.

What we can connect

Business management software

CRM, ERP, accounting, billing, planning, document management, customer support, or logistics platforms: we connect the tools that already structure your company so teams stop re-entering data between departments.

Web and mobile applications

We create a shared foundation so your web interfaces, mobile apps, extensions, and internal tools use the same data, permissions, and business rules.

Partner platforms and external services

We integrate the services your activity needs: payments, mapping, messaging, signature, identity, delivery, or industry platforms. When integration brings specific constraints, we translate them into rules your teams can control.

Legacy systems and file exchanges

Not every system has a modern API. Depending on what is available, we can work with structured imports and exports, secure files, an accessible database, webhooks, or an intermediate layer. The chosen approach depends on the reliability and rights offered by the existing system.

APIs for your clients and partners

Your product can become integrable by other companies. We design public APIs with authentication, permissions, versioning, usage limits, consistent responses, and developer documentation.

Several forms of integration, one operational goal

Real-time synchronisation

A change immediately triggers an exchange. This fits when status must be visible quickly, an action depends on the data, or a user is waiting for confirmation.

Scheduled synchronisation

Data is grouped and exchanged at defined intervals. This can be better for large volumes, reporting, or systems that cannot process updates immediately.

Event-triggered workflow

Creating a customer, validating an order, or closing a mission launches a sequence of actions: file creation, notification, document generation, or transmission to a partner.

Central API

When several interfaces use the same product, a central API helps keep rules, rights, and data consistent. It can also open selected capabilities to clients or partners without exposing your internal tools.

An integration must also work when something goes wrong

A demo can stick to the happy path. A production integration must handle the rest.

We typically include:

  • validation of data format and consistency;
  • duplicate prevention on retries;
  • automatic retries after a temporary interruption;
  • logging of important exchanges;
  • alerts when an action needs intervention;
  • permissions limited to data that is actually needed;
  • handling of limits and constraints imposed by external services;
  • a versioning strategy when the API must evolve;
  • documentation that makes the integration understandable and maintainable.

That reliability is what turns a technical connection into operational infrastructure.

Our integration method

1. Map systems and responsibilities

We identify the software involved, data owners, available formats, volumes, exchange frequency, and access constraints. We decide which source is authoritative for each piece of information.

2. Define data and exchange rules

We specify what goes in, what goes out, required transformations, and triggered actions. Incomplete cases, duplicates, and corrections are handled at this stage.

3. Build the integration or API

We build the connection layer with a clear separation between business rules and the quirks of each external service. That structure makes testing and future changes easier.

4. Test without disrupting operations

We use available test environments and representative scenarios. Rollout is progressive when the exchange touches a critical process or a large volume of data.

5. Monitor and document

We make exchanges traceable, plan useful alerts, and document the flows. Your team should be able to tell a pending update from a temporary error and a case that needs correction.

What you get

  • a map of systems and data flows;
  • clear ownership for each piece of data;
  • an integration adapted to your real constraints;
  • controls for errors, duplicates, and interruptions;
  • appropriate authentication and permissions;
  • logs and alerts useful for operations;
  • tests covering normal paths and exceptions;
  • technical and operational documentation;
  • support during deployment.

Integrations used in real products and operations

taap.it — A public API to automate client work

We designed the API architecture that powers the mobile app and browser extension, while giving clients and partners controlled public access to product capabilities. The project includes authentication, workspaces, permissions, versioning, and a multilingual documentation portal.

TaxiGer — Connecting taxi operations to a regulatory platform

Data entered by drivers in TaxiGer feeds administrative workflows and, in Flanders, the required transmissions to the official Chiron platform. The integration avoids managing trips, service status, and regulatory data separately.

IHPO and Electro Dépôt — Linking in-store terminals to existing logistics

Bookings entered on terminals are validated by teams, then sent to the central logistics system. Stores get a customer-ready journey without replacing the delivery infrastructure already in place.

Institut Jules Bordet — Helping specialised systems work together

In a hospital environment, we worked on integrating radiotherapy and imaging tools with existing information systems. The priority was data consistency, cross-service workflows, and the validations required in a clinical context.

MonPIF — Connecting ChatGPT to a specialised educational knowledge base

We structured the educational frameworks of the Fédération Wallonie-Bruxelles so they can be queried by people and by other systems. A working MCP connector lets ChatGPT search that base before generating an activity tied to a level, subject, or competence. The same data feeds both the public Explorer and AI-assisted workflows.

API, automation, or business application?

  • Your tools work, but data still moves manually: choose systems and API integration.
  • The issue is mainly a chain of tasks, approvals, and documents: explore business process automation.
  • You lack a central interface to run operations and roles: explore our custom business applications.

Frequently asked questions about systems and API integration

Can any software be connected?

Feasibility depends on the access the vendor provides: API, webhooks, exports, imports, or other authorised mechanisms. We check those options before recommending an approach. When a system is fully closed, we clearly explain the limits and alternatives.

What if our software has no API?

An integration can sometimes use structured files, a secure exchange, an accessible database, or a vendor-provided module. We favour documented, stable methods. Fragile click-simulation automations are only considered with a clear understanding of their risks.

Do we need real-time data sync?

Not always. Real time is useful when an immediate action depends on it. Scheduled sync can be simpler and more robust for reporting or bulk processing. We choose frequency based on the business need, not a technical effect.

How do you avoid duplicates and inconsistent data?

We define a source of truth, stable identifiers, and replay rules. The same operation can be resent without running twice, and conflicts are flagged instead of hidden.

Can you build a public API for our clients?

Yes. We can design the exposed operations, authentication, permissions, versioning, usage limits, and documentation. A public API is treated as a product in its own right, with an adoption path and stability commitments.

Who can maintain the integration after go-live?

We produce documentation and a code structure designed for maintenance. Depending on your organisation, we can handle follow-up, work with your technical team, or prepare a progressive handoff.

Your teams should not act as the API between your tools

Show us the systems you use, the data being retyped, and the actions that still depend on an export or an email. We will determine the most reliable way to connect them.
