Service desk Custom API integration ITSM & ESM

Custom TOPdesk integration development

Appfront develops custom TOPdesk integrations that connect your service desk to monitoring, HR systems, identity providers and your own applications. Using TOPdesk's official REST API, we build stable integrations that speed up incident handling, eliminate manual work and keep your ITSM processes consistent.

What is a TOPdesk integration?

TOPdesk is the ITSM platform from the Dutch software vendor of the same name based in Delft, used worldwide by more than 10 million users. The platform supports ITIL processes such as incident management, change management, asset management and knowledge management, and is increasingly deployed beyond IT for facilities management, HR services and education.

A TOPdesk integration connects this service management platform to the other systems in your organisation. Monitoring tools automatically create incidents, assets are synchronised with your CMDB, the self-service portal retrieves employee data from HR systems, and changes are translated into tasks in project management tools. The result: less manual ticket handling, faster turnaround times and more reliable SLA reporting.

Appfront builds these integrations to measure using the official TOPdesk REST API. We align scope, routing logic and error handling with your actual service processes, rather than a generic connector that only solves part of the problem.

Incident automation

Incidents are automatically created, categorised and assigned based on source data from monitoring, email or forms. Less manual logging, faster response times.

Self-service portal

The TOPdesk self-service portal is enriched with data from HR and facilities systems. Employees submit requests with pre-filled details, the correct category and direct routing.

Asset integration

Assets in TOPdesk are synchronised with your CMDB, procurement system or device management platform. Configuration items stay up to date without manual entry.

Our development process for TOPdesk integrations

We work to a methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your service processes through to go-live and ongoing management, every step is focused on an integration that delivers immediate value to your service team.

1
Analysis & scope

We map your ITSM processes: which entities (incidents, changes, assets, people) need to be connected, in which direction data flows, and which routing logic applies.

2
Architecture

We design the integration architecture, choose the right authentication method (API token, OAuth, SAML) and set out a strategy for error handling, retries and fallback scenarios.

3
Development

Implementation with automated tests, structured logging and monitoring. You see working builds along the way, so we can adjust early based on real service data.

4
Go-live & management

Controlled go-live with data validation and a parallel run period, followed by ongoing management, proactive monitoring and further development of the integration.

What a TOPdesk integration delivers in practice

Every integration is developed specifically for your service processes. Below are the features we most often build for organisations that want to connect TOPdesk with the rest of their systems landscape.

Ticket synchronisation

Incidents and service requests from TOPdesk are synchronised bidirectionally with external ticketing systems, project management tools or customer portals. Status updates, notes and attachments flow through automatically.

Self-service portal

The TOPdesk self-service portal is linked to HR systems, Active Directory and facilities databases. Employees see only relevant forms, and their requests are automatically enriched with department and location details.

Asset management sync

Configuration items, hardware assets and software licences are synchronised between TOPdesk and your CMDB, MDM platform or procurement system. Changes in ownership, location or status are passed on automatically.

Monitoring integrations

Alerts from Zabbix, PRTG, Nagios, Datadog or Azure Monitor are automatically converted into incidents in TOPdesk. When the issue is resolved, the ticket is updated or closed, including the correct priority, category and assignment group.

Reporting & dashboards

Service data from TOPdesk is combined with operational data in custom dashboards or in tools such as Power BI, Looker Studio or Tableau. SLA compliance, lead times and workload become visible to management and team leads.

SSO & identity

TOPdesk is connected to your identity provider via SAML 2.0 or OpenID Connect. Employees log in with their existing credentials, and provisioning and deprovisioning happen automatically when people join or leave.

Typical use cases in practice

TOPdesk is used across a wide range of domains, from traditional IT service desks to facilities management and HR. The integration needs differ fundamentally from one domain to another. We see a number of patterns recur often.

IT service desks

The classic use case: TOPdesk as a central ITSM platform, connected to monitoring tools, Active Directory, endpoint management and knowledge bases. Incidents are created automatically from alerts, changes follow an automated approval flow, and SLA clocks run without manual starts. See also our wider services around API integrations.

Facilities management

TOPdesk is increasingly used for facilities requests: room bookings, faults in climate systems, cleaning requests or office moves. An integration with building management systems, IoT sensors or booking software makes it possible to automatically route requests to the right facilities team.

HR service delivery

HR departments using TOPdesk for internal service delivery connect the platform to their HRIS (AFAS, Visma, Workday). Joiners and leavers automatically trigger tasks: creating accounts, preparing hardware, ordering access passes. The entire onboarding chain runs through automated service flows.

Healthcare & education

In healthcare organisations and educational institutions, TOPdesk serves as the central point of contact for IT, facilities and medical equipment. Integrations with EHR systems, pupil administration or equipment management ensure that requests reach the service team with the right urgency and context, in compliance with privacy legislation and NEN 7510.

Technology we use

We build TOPdesk integrations using modern, well-maintained stacks. The precise choice depends on your existing IT landscape and preferences, so your own team can manage or further develop the integration. We are happy to work alongside your TOPdesk consultant and deliver clear documentation.

Why choose Appfront for your TOPdesk integration?

Appfront has extensive experience building API integrations for organisations in the Netherlands that want to automate their service management. We always start with a thorough analysis of your existing ITSM processes and systems landscape. An integration must not only work technically but also add practical value to the daily work of your service team.

For every integration, we write clear documentation and make sure your own team, or your TOPdesk consultant, can understand and manage the integration. No black box, but transparent code and clear agreements on monitoring, alerting and maintenance.

You work with a dedicated point of contact who understands both the technical and functional side of service management. This keeps communication lines short and speeds up decisions when choices need to be made about routing logic, prioritisation or escalation rules.

Security and privacy in TOPdesk integrations

Service management data regularly contains personal data, employee data and sometimes medical or other sensitive information, particularly in healthcare and education environments. Appfront treats this as a starting point for every integration: we do not store unnecessary data, we encrypt sensitive information both in transit and at rest, and we document data flows so that your record of processing activities stays up to date.

For integrations in the healthcare sector, we take NEN 7510 and its specific requirements for access control, logging and data minimisation into account. For all environments, authentication runs through secure methods, and API tokens are used with minimal permissions.

Frequently asked questions about TOPdesk integrations

Answers to the questions we get asked most often about custom TOPdesk integrations.

A TOPdesk integration is a technical integration that lets TOPdesk, the ITSM platform from Delft, exchange data with other systems in your organisation. It works through TOPdesk's official REST API. Think of automatically creating incidents from monitoring tools, synchronising assets with a CMDB, or linking the self-service portal to HR and facilities systems.

A custom integration makes sense when standard marketplace connectors do not meet your specific workflows. For example, with complex incident routing logic, bidirectional synchronisation with an external ticketing system, or when you want multiple TOPdesk environments to work together. Organisations that use TOPdesk beyond IT, for facilities management or HR, also frequently need integrations that go further than the standard offering.

The timeframe depends on complexity. A one-way integration, for example monitoring alerts that automatically create incidents, can be operational within a few weeks. Bidirectional synchronisation across multiple entities (incidents, changes, assets, people) typically takes six to ten weeks. After an intake meeting, we provide a realistic schedule.

We work with TOPdesk's official REST API and build the integration layer in Node.js, Python or .NET, depending on your existing IT landscape. Authentication runs through API tokens or OAuth. For SSO integrations, we use SAML 2.0 or OpenID Connect. The integration runs in Docker containers in your own cloud (Azure, AWS) or on-premise, with structured logging and monitoring.

Yes. We regularly build integrations between TOPdesk and monitoring platforms such as Zabbix, PRTG, Nagios, Datadog and Azure Monitor. Alerts are automatically converted into incidents in TOPdesk, including prioritisation, categorisation and assignment to the right operator group. When the issue is resolved, the incident is automatically updated or closed.

The investment depends on the number of systems to integrate, the complexity of the data flows and routing logic, the desired synchronisation frequency and the amount of custom work in the business rules. Ongoing management and monitoring also play a part. We always provide a clear quote following a no-obligation analysis of your situation.

Yes. All integrations are developed in line with GDPR and security best practices. We encrypt data in transit and at rest, use API tokens with minimal permissions, and limit the scope of personal data exchanged. For healthcare integrations, we also take NEN 7510 into account. Data flows are documented for your record of processing activities.

Yes. Appfront regularly takes over existing integrations, including those built by another party or developed in-house. We carry out a code and architecture review, document the integration and draw up an improvement plan. Common improvements include better error handling, retry mechanisms, monitoring and replacing outdated authentication methods.
