“We need to connect our new VMS to our ERP and HRIS, it should be simple, right?”
Sounds familiar?
For CIOs and IT teams, this kind of request happens during the implementation of a new tool. But behind every integration lies a maze of security rules, legacy systems, APIs, and data governance policies that make even small projects complex to deliver.
Eleven VMS changes that equation with its API-Powered architecture. It connects securely and non-intrusively to your existing IT ecosystem, giving teams full control and zero lock-in. Integration evolves as your ecosystem does.
What Makes an API-Powered Integration Strategy Essential?
How you integrate new solutions is just as important as the solution itself. An API-Powered approach is no longer a “nice-to-have”, it’s the foundation of a secure, scalable, and future-proof IT strategy.
Here’s why:
Decoupling brings control
Traditional integrations often lock organizations into rigid middleware or vendor frameworks that are costly to maintain. An API-Powered approach keeps systems lightweight, independent, and fully under IT’s control.Evolutive design: Scale and adapt as systems or regulations evolve
As business models, compliance rules, or internal systems evolve, API-Powered integrations evolve with them, adding new use cases without breaking existing ones.Client ownership: zero-maintenance costs
With APIs, clients build and own their own interfaces. This eliminates dependency on external vendors for updates or fixes and reduces hidden long-term costs.
The Eleven VMS API Advantage
Secure and Modern Authentication
In enterprise integrations, security starts with authentication. Eleven VMS implements the OAuth2.0 authorization framework, the gold standard for machine-to-machine connections. Every request is verified through a short-lived access token (around one day) which minimizes exposure and eliminates the risks tied to static, long-term credentials.
At the same time, Basic Authentication is being phased out, reinforcing Eleven VMS’s commitment to a security-first, future-proof integration model aligned with modern enterprise standards.
Stability at Scale
Procurement data flows are often high-volume and business-critical. That's what, on a regular basis (cf. Interface Audit), our APIs are attending daily from 70k to 100 k API Calls, and the trend is increasing constantly.
To support IT teams in managing safe deployments, Eleven VMS provides dedicated testing and production environments, allowing developers to validate integrations in controlled conditions before going live. In other words, Eleven VMS speaks the same language as modern DevOps: controlled CI/CD pipelines, predictable load, and zero surprises in production.
Non-Intrusive Integration
One of the biggest concerns for CIOs is how new systems will interact with existing infrastructure. Eleven VMS APIs are designed to be non-intrusive, meaning they integrate seamlessly into even the most complex and security-conscious ecosystems.
No disruptive architectural changes are required. Instead, APIs fit into existing IT governance and security policies, ensuring that Eleven VMS becomes an enabler, not a disruptor.
Beyond APIs: Practical Benefits for IT Teams
A Bidirectional Model
Our clients can make Eleven VMS to consume their APIs, or consume the Eleven VMS one, it is our bidirectional flexibility. It ensures that integration adapts to their IT architecture, not the other way around for a non-intrusive connection model where IT leaders remain in full control of how systems interact.
Ownership & Zero Maintenance
Eleven VMS gives clients full ownership of their connectors to make the integration belong to the IT team, with no hidden maintenance costs or lock-ins.
As Eleven VMS evolves, API enhancements are backward-compatible, so connectors can continue to function without disruption.
Master Data Consistency
APIs allow the propagation of ERP and e-procurement master data, such as order number, vendor codes, or cost centers, directly into Eleven VMS objects.
This ensures every transaction is accurate, compliant, and traceable, while maintaining a single source of the truth across your ecosystem.
Continuous Enhancement
Integration isn’t a one-time project and must evolve alongside business and IT needs. Eleven VMS continuously releases new API features, all designed for non-disruptive adoption. Clients gain access to new capabilities immediately, without breaking existing workflows.
Visual Comparison: Traditional Integration vs. API-Powered with Eleven VMS
With its API-Powered design, Eleven VMS empowers IT teams to integrate securely, independently, and at scale, making APIs the preferred and most powerful approach.
That said, API-Powered doesn’t mean API-only. Depending on your organization’s architecture, maturity, and data governance, other integration models, such as middleware or webhooks, can complement APIs to achieve a fully connected ecosystem.
