Connecting HR systems without a large IT project is perfectly possible in many cases. Modern HR software offers standard integration options via APIs or ready-made connectors, allowing you as an HR professional to stay in control yourself. In this article, we answer the most frequently asked questions about HR integrations, from the easiest connections to the situations where you do need IT.
Which HR systems are easiest to integrate?
The easiest HR systems to integrate are platforms that work by default with open APIs or their own integration marketplace. Think of widely used HR suites such as Afas, Nmbrs, HiBob, or Personio. They offer ready-made connectors to payroll software, scheduling tools, and absence management systems, so you can get started without custom development.
The key word is "standard integration." The more a system is built on open standards, the less technical knowledge you need to connect it with other tools. Systems that have been working together in the same HR ecosystem for years often have pre-built connectors that you activate via a dashboard rather than programming them.
What to look for when choosing connectable HR software:
- Does the system have its own integration marketplace or app store?
- Are commonly used tools like Slack, Teams, or your LMS supported by default?
- Is documentation available that non-technical users can also understand?
- Does the vendor offer support when setting up the integration?
Systems that have been working together in the same HR ecosystem for years often have pre-built connectors that you activate via a dashboard. That saves considerably in time and cost compared to custom development.
What is an API integration and do you need IT knowledge for it?
An API integration is a standardized connection that allows two software systems to exchange data with each other. API stands for Application Programming Interface. In practice, it means: system A automatically sends information to system B, without anyone having to type it over manually. For basic integrations, you don't need IT knowledge if the vendor provides a user-friendly configuration environment.
The distinction lies in the type of API usage. There are two situations:
- Configuration via an interface: you click an integration in a dashboard, enter an API key, and set which data is synchronized. This requires no programming knowledge.
- Custom development via code: you build your own integration based on the API documentation. This does require technical knowledge and is reserved for more complex situations.
For most HR integrations — such as pushing new employees from your ATS to your HRIS or synchronizing leave records with your payroll processing — the first option is sufficient. Vendors are investing more and more in no-code configuration tools, precisely because HR teams want to be able to work independently.
How do you connect HR systems without involving IT?
Connecting HR systems without IT works best via three routes: through built-in integrations from the vendor, via a no-code integration platform such as Zapier or Make, or via an iPaaS solution specifically designed for HR workflows. In all three cases, you set up the integration through a visual interface, without writing any code.
The practical steps are generally as follows:
- Map out your systems. Which HR tools do you use and which data needs to flow between which systems?
- Check the integration marketplace. Does your HR system already offer a ready-made connector to the other system?
- Use a no-code platform. If there's no direct connector, connect both systems via a middleware layer such as Zapier or Make.
- Set up triggers and actions. Determine which event in system A triggers an action in system B — for example: new employee created, absence report submitted, or onboarding completed.
- Test with real data. Check whether the correct fields are being passed through and whether the timing is right.
- Monitor the integration. Set up error notifications so you know quickly when a synchronization fails.
Many HR teams use this approach to connect their employee satisfaction surveys to their HRIS, so that invitations are automatically sent at the right moment — such as after onboarding or at the end of a probation period. This saves manual work and increases response rates. Want to know how to continuously collect employee feedback and connect it to your HR processes? We explain that further below.
What are the risks of HR integrations without an IT department?
The main risks of HR integrations without IT are: data quality issues due to incorrect field settings, privacy risks when personal data is passed through unsecured, and integrations that silently stop without anyone noticing. These risks are manageable, but they do require deliberate choices when setting things up.
Specifically, what to watch out for:
- GDPR compliance: make sure both systems you are connecting comply with the GDPR. Do not process personal data through tools that store data outside the European Economic Area, unless appropriate safeguards are in place.
- Error handling: always set up error notifications. An integration that stops halfway through produces incomplete data, and this often only becomes apparent after the damage is done.
- Field definitions: check whether fields in both systems have the same meaning. A "start date" in system A might be the contract date; in system B it could be the first working day. That difference causes errors in reports.
- Access management: limit who can modify the integration. The fewer people who have administrator access, the smaller the chance of unintended changes.
The good news: most no-code platforms offer built-in logging and error notifications. Combine that with a short checklist when setting things up, and you'll catch most risks without needing IT to be involved.
When is an IT project for HR integration truly necessary?
An IT project is necessary when you are dealing with complex data models, legacy systems without a modern API, high volumes requiring real-time synchronization, or strict security requirements that demand custom configuration. In those cases, a no-code approach offers insufficient control or scalability.
Typical situations where IT does need to be at the table:
- You work with an ERP system that has no standard REST API and requires custom integrations.
- Your organization processes highly sensitive personal data, such as medical or payroll data, and imposes additional security requirements on the connection.
- The integration touches multiple systems simultaneously and requires a central data layer or data warehouse.
- You need real-time synchronization at high transaction volumes — for example, in an organization with thousands of employees and daily mutations.
- Compliance requirements, such as ISO 27001 requirements, stipulate that integrations must be documented, tested, and audited by a technical party.
The rule of thumb: if the integration can be set up once and contains little exception logic, you can do it yourself. As soon as you need rules, conditions, or transformations that go beyond "send field X to field Y," IT involvement is advisable.
How do you ensure HR data remains reliable after integration?
HR data remains reliable after an integration if you safeguard three things: a clear owner per data source, regular checks on data quality, and a process for resolving discrepancies. Reliable data is not just a technical issue — it is also an organizational one.
In practice, this means:
- Appoint a data source owner. Who is responsible for the accuracy of the data in system A? That person is also the first point of contact if something goes wrong in the integration.
- Monitor automatically. Use the logging of your integration platform to check daily whether the synchronization was successful and whether the expected number of records was passed through.
- Conduct periodic audits. Spot-check the data in both systems. Do names, employment records, and dates match?
- Document changes. Every modification to the integration — a new field, a changed trigger, a new condition — should be recorded. That way you always know why something was changed.
Reliable HR data is the foundation for reliable insights. If you connect employee feedback to HR data, you want to be sure that the link between an employee and their team is correct. Otherwise, you send a manager a report that isn't about their own team, and that undermines trust in the entire program.
How CYS Group helps connect HR data and employee feedback
CYS Group helps HR teams treat employee feedback not as a standalone survey, but as a continuous signal that connects to your existing HR processes. Our platform cx.management is designed to integrate with your HR environment — without requiring a large IT project.
What that means in practice:
- Automatic invitations at the right moments — such as after onboarding, on a work anniversary, or after a reorganization — based on triggers from your HR system.
- Team reports that managers can use directly, without HR having to compile them manually.
- Linking engagement scores to absence and turnover data, so you not only see that something is happening, but also where and why.
- Closed-loop follow-up via our case management: a signal from an employee leads to a concrete action, not a report that ends up in a drawer.
- GDPR-compliant and ISO 27001-certified, so you can be confident that personal data is processed securely.

Frequently Asked Questions
How long does it take on average to connect two HR systems via a no-code platform?
A simple connection via a no-code platform such as Zapier or Make is in many cases up and running within a day. Most of the time is spent mapping out the data flows and testing with real data, not on the technical configuration itself. For more complex integrations with multiple triggers and conditions, expect a few days to a week, depending on the number of systems you are connecting.
What are common mistakes when setting up HR integrations yourself?
The most common mistake is skipping the testing phase with real employee data. As a result, errors in field definitions or timing only become apparent in production, sometimes with consequences for payroll processing or absence registration. A second common mistake is the absence of error notifications and monitoring, which means a failed connection can go unnoticed for weeks. Always work with a fixed checklist when setting things up and configure automatic alerts right from the start.
Can I expand an existing HR integration later without having to rebuild everything from scratch?
Yes, that is one of the advantages of no-code integration platforms: you can extend existing workflows by adding extra steps, triggers, or conditions without rebuilding the entire connection. Make sure you document any changes so you always know what was adjusted and why. For larger expansions — such as adding a third system or processing sensitive data — it is wise to verify whether the existing setup still meets your GDPR and security requirements.
How do I know whether my HR system is GDPR-compliant when connecting it to an external platform?
First, check whether the external party offers a Data Processing Agreement (DPA) and whether data is stored within the European Economic Area. Also check whether the platform holds relevant certifications such as ISO 27001 or SOC 2. If in doubt, consult your privacy officer or Data Protection Officer (DPO) before activating the connection, especially when it involves special categories of personal data such as health or payroll information.
What is the difference between an iPaaS solution and a tool like Zapier or Make?
Zapier and Make are accessible no-code tools suitable for simple to moderately complex integrations, ideal for HR teams that want to get started quickly without technical knowledge. An iPaaS solution (Integration Platform as a Service) offers more control, scalability, and enterprise features such as advanced error handling, role-based access management, and extensive logging. For larger organizations with many systems, high data volumes, or strict compliance requirements, an iPaaS is generally the better choice.
Do I need to check the integration again every time a new employee joins or a system change is made?
Not for every new employee, because a properly configured integration processes new records automatically based on triggers. However, it is advisable to actively test the integration whenever system changes occur, such as an update to your HRIS or a change in field structure. In addition, schedule a periodic audit — for example every quarter — where you spot-check whether the data in both systems still matches.
Is it worthwhile to connect employee feedback to my HR system if we only have a small HR team?
Especially for small HR teams, the integration is valuable because it eliminates manual work that would otherwise take up a lot of time. Automatic invitations based on onboarding data or work anniversaries mean you no longer need to maintain separate lists or send emails manually. Furthermore, the integration ensures that feedback is directly linked to the correct employee and team, which improves the quality of reports without requiring any additional capacity.
