API integrations that make your software work together
Want to connect your software, app, CRM, ERP, portal or external tools? With an API integration, your systems exchange data securely, automate processes and make information available in the right place.
DTT develops, integrates and connects APIs for organisations that want control over their data and digital processes. From building an integration with an existing API to developing a custom API for partners, users or internal systems.

API integrations for apps, software and digital solutions
Having an API integration built is often the step that turns separate systems into one working digital whole. Think of an app that retrieves data from a CRM, a portal connected to an ERP system, or internal software that brings together information from multiple data sources.
DTT develops API integrations as part of broader digital solutions. That means we look not only at the technical integration itself, but also at its role within your product, organisation and future plans. If you have custom software built, for example, the quality of the integrations often determines how stable and scalable the solution ultimately becomes.
An API integration is also often important when you have an app created. The app needs to communicate securely with systems behind the scenes, such as user management, payment solutions, dashboards or external data sources. By setting this up properly from the start, you prevent integrations from holding back growth later on.
An API integration can also support AI integration, for example when existing software needs to be connected to AI models, internal data sources or automations. The result is not a separate technical add-on, but a solution that fits within your existing digital environment.
Whether you want to connect existing systems or have a custom API developed for partners and external applications, DTT provides a technical foundation that is reliable, secure and maintainable.
Why have an API integration built?
Less manual work: systems exchange data automatically.
Better data quality: information stays up to date and consistent.
Stable software integration: fewer errors, outages and data loss.
Ready for growth: easier to expand with new systems.
How we work
01
We investigate what needs to be connected
We start with your systems, data flows and processes. Which information needs to be available where? Which systems are leading? And where do errors, delays or duplicate work occur today?
This allows us to determine which API integration is needed and how to set it up smartly from a technical perspective.
02
We determine the best technical approach
Not every integration calls for the same solution. Sometimes an integration with an existing API is enough. In other situations, we develop middleware, build a custom API or set up an event-driven architecture.
We choose the approach that suits your organisation, software and future plans.
03
We develop, test and monitor the integration
DTT builds APIs with attention to security, documentation, versioning and error handling. After development, we test thoroughly and set up monitoring and alerting.
That way, you don’t just know the integration works, but also when action is needed.
What you can expect
A reliable connection between your systems
An API integration is about more than just passing data along. The integration needs to fit logically with your processes, handle information securely and keep working when software or data flows change. That is why we look at the entire chain, from source data to end user.
Developing, integrating and connecting APIs
DTT helps with a wide range of API challenges. We develop custom APIs using REST or GraphQL, integrate existing third-party APIs and connect systems that don’t naturally work together. Think of payments, identity, AI models, dashboards, CRM systems or ERP software.
A maintainable foundation for further growth
A good API is understandable for developers who join later. That is why we work with clear documentation, versioning, monitoring and well-defined management agreements. The result is a solution that works today and remains manageable tomorrow.
Frequently asked questions
When should you have an API integration built?
An API integration is worth considering when systems don’t work well together, data is transferred manually or information doesn’t match across different places. Think of an app that needs data from a CRM, a portal that has to be connected to an ERP system or a product you want to open up to external applications.
How much does an API integration cost?
The cost of an API integration depends on the number of systems, the quality of existing APIs, the volume of data, the security requirements and the desired error handling. A simple integration usually requires less development time than a project involving multiple systems, middleware and extensive business logic.
Can DTT also improve an existing API integration?
Yes. DTT can analyse, stabilise and extend existing integrations. We look at error messages, data quality, performance, logging, documentation and maintainability. This gives you more control over integrations that are currently unreliable or require a lot of maintenance.
Can you also develop a custom API?
Yes. DTT can develop a custom API for your organisation, product or platform. This allows you to make data or functionality available to other applications, partners or internal systems. We take security, access rights, documentation and versioning into account.
How long does it take to build an API integration?
The lead time depends on the complexity. A simple integration between two systems can be delivered faster than a project involving multiple data sources, middleware and extensive business logic. During the analysis phase, we clarify what is needed, which steps will follow and what timeline is realistic.
Is an API integration secure?
An API integration can be set up securely when authentication, authorisation, encryption, logging and error handling are properly implemented. DTT takes security into account from the start in every technical decision, so the integration matches the sensitivity of your data and the requirements of your organisation.
