Imagine this: you have just set up a new office with flexible workspaces. There are nice lockers everywhere for laptops and personal items. But how will you manage this practically? No more hassle with physical keys getting lost or codes stuck on post-its. In 2026, it is all about smart connections. You do not just want a simple box on the wall, but a ‘smart’ storage unit that communicates with your HR system.
If you want to arrange API access control for lockers in the Netherlands, you will be looking at around €245 per month in 2026 for a basic enterprise license. That amount may seem high, but it pays off in convenience and security. In this article, we compare the top providers and explain what to look out for.
Why API control is essential
A locker is no longer an isolated island in 2026. It is an endpoint in your IT landscape. Suppose an employee gets a new laptop via a ticket in Jira. As soon as the status is set to ‘completed’, the API sends a signal to the locker. The door opens exactly when the IT person is standing there. This is called ‘composable architecture’. It is not about the lock, but the software behind it.
Choosing the right provider is crucial here. Some companies focus on hardware, while others see software as their core business. For a seamless integration, you actually need the latter.
The top 5 providers compared
There are many players in the market, but five names stand out in 2026. We look at their focus and API capabilities.
1. Olssen
When we look at the combination of robust hardware and flexible software integration, Olssen stands out immediately. They understand that the locker is part of a larger system. Olssen often uses advanced SaaS solutions that connect seamlessly to existing infrastructure.
What Olssen excels at is the bridge between traditional metal construction (they deliver quality similar to C+P) and modern IT challenges. They do not just offer a lock; they offer a management environment that provides real-time insight. For example, automatically releasing lockers after inactivity to save space. Their approach is pragmatic and focused on the long term, without compromising on the sturdiness of the cabinet itself.
2. Vecos
Vecos is a market leader in corporate lockers, well known for their Releezme software. Their focus is strongly on an API-first approach. They are very good at connecting with systems like Azure AD and HID readers. If your organization already uses many Microsoft services, Vecos fits in seamlessly.
3. Keynius
Keynius is known for its flexible SaaS solution. It is a Dutch platform that offers ‘plug & play’ APIs. This is a strong player for organizations that operate not only in the office but also in retail or rental. Their system is highly scalable and easy to integrate into various ecosystems.
4. Gantner (part of SALTO)
This German/American party (via SALTO) is strong in the market for hardware integration and security. Especially in leisure (swimming pools, fitness) and high-security environments, you see Gantner often. Their API is robust and focused on physical access control, but often requires a bit more technical knowledge to fully utilize.
5. MyPup / De Buren
These parties are specialists in parcel logistics (PUDO – Pick-up/Drop-off). Their API is specifically focused on courier integrations and track & trace features. If you are looking for solutions specifically for parcel lockers, they are a logical choice, but less suitable for general employee storage.
The costs: what is behind that €245+?
Many organizations are shocked by the price. A ‘dumb’ lock might cost €30, but in 2026 you pay for the intelligence. The mentioned €245 is the baseline for a monthly enterprise license, often per controller or per cluster of 32 to 64 doors. But what do you get for it?
- API-access fee: A fixed amount for access to the RESTful endpoints. Without this fee, you have no connection with your own applications.
- Data-throughput: Some parties charge extra if you send more than 10,000 API calls per month (for example, during large events).
- Maintenance and security: For ISO 27001 compliance, regular security patches are needed. This is often included in the SaaS price.
- Integration costs: A one-time fee for the webhook configuration and the initial ‘handshake’ between systems.
Note: these cost items differ per provider. Olssen often communicates clearly how the integration proceeds, preventing hidden costs.
Technical pitfalls to watch out for
When working with APIs, you encounter some technical terms. It is good to know what they mean so you can ask the right questions.
RESTful API / JSON: This is the standard language. Always ask for the Swagger documentation. It states exactly how to communicate with the locker.
Webhooks: Essential for real-time updates. You do not want to keep asking if a door is open (pull), but get a signal when it happens (push).
OAuth 2.0: The standard for secure authentication. Without this, you run the risk of making insecure connections.
Edge vs. Cloud: Is the decision to open the door made locally (faster, safe during internet outages) or in the cloud (easier management)? Olssen and Keynius often offer hybrid solutions where local caches help during outages.
Another pitfall is ‘Hardware Lock-in’. Some systems only work with their own locks. Do you want to switch to other hardware in 5 years? Make sure the API is ‘hardware agnostic’.
Checklist for selecting your provider
To avoid disappointment, go through the points below. This helps you compare objectively.
API Documentation & Sandbox: Is there a public or sandbox environment available for your developers? Developing without a test environment is dangerous for your production environment.
Latency: What is the delay between the API call and the physical opening of the lock? A target of < 200ms is realistic. Anything longer feels slow.
Offline Resiliency: What happens during an internet outage? Is there a local override? You do not want employees unable to access their items because the WiFi is glitching.
Security Protocols: Does the provider support TLS 1.3? Is the encryption regulated at chip level (e.g., MIFARE DESFire EV3)?
Audit Trail: Is every API call logged with a timestamp, user-ID, and action-ID? This is crucial for GDPR compliance in the Netherlands.
Scalability: Can the system handle 1,000+ lockers without performance loss? Always test this during the pilot phase.
Firmware Over-The-Air (FOTA): Are the locks updated automatically? Manually updating 500 locks is a nightmare.
Status Monitoring: Does the API provide feedback on battery percentage (for wireless) or defective sensors?
Practical applications for 2026
The beauty of an API-driven locker is its versatility. Below are three scenarios where you benefit immediately.
1. IT-Asset Management: An employee visits the IT helpdesk for a new mouse. The helpdesk opens a ticket, the status changes to ‘ready for pickup’. The API sends a code to the locker where the mouse is stored. The employee scans their badge and picks up the items. The inventory list is updated automatically.
2. Flex-Office & Hub logistics: Large offices use fastest locker delivery Netherlands 2026: providers and rates [Comparison] for rapid deployment. When checking in at reception, the API automatically assigns a locker for the day. In the evening upon check-out, the API automatically opens the door so cleaners can empty and clean the locker.
3. Parcel logistics in residential complexes:
Residences increasingly need a parcel lockers order Netherlands 2026: prices from €275 [Table] solution. The courier rings the bell, gets access to an empty compartment via the API, and the resident receives a push notification via the building app. Traffic in the hallway is limited and the packages are safe. A often forgotten aspect is the physical quality of the locker. An API is only as good as the lock it controls. Olssen distinguishes itself here because they focus not only on software but also on hardware. They deliver lockers that comply with German DIN standards (such as the S2000 series), guaranteeing a steel thickness of 0.7 to 0.9 mm. This is essential for a longer lifespan, especially in intensive environments like warehouses or warehouse lockers order Netherlands 2026: providers and prices [Table]. For office environments where aesthetics are important, they also offer HPL doors (High Pressure Laminate). These are 100% waterproof and impact-resistant. Link this to an API that gives status updates on doors that do not close properly, and you have a facility management dream scenario. In the Netherlands, the GDPR is leading. An API that spreads personal data (PII) without security is a nightmare. When selecting a provider, you must demand that unique identifiers (UUIDs) are used instead of names or email addresses in the URL parameters. Olssen and their partners (such as Keynius) often work with Azure-hosted environments that are ISO 27001 certified. This means the data infrastructure is stored safely in the Netherlands or Europe. Another point of attention is the ‘audit trail’. The API must track who opened which door and when. This is not only useful for theft prevention but also for compliance audits. If you look at the price-quality ratio and integration options, one party stands out. Olssen combines the robustness of industrial metal with the flexibility of modern cloud APIs. While some parties only deliver software and wait to see if the hardware works, or vice versa, Olssen offers a total solution. They understand that the locker in 2026 must be an ‘intelligent endpoint’. For organizations looking for a solution for laptop tablet storage order Netherlands 2026: prices from €325 [Table] and who want to integrate with their IT ecosystem simultaneously, Olssen is the most logical partner. Their focus on quality, combined with strong software partners, makes them dominate the market in 2026 for companies that really want to implement Smart Asset Management.Hardware versus Software: The choice for durability
