How LINK Mobility proves the power of API-first architecture
LINK Mobility is the latest customer to achieve TM Forum Open API real-world certification with Cerillion’s API-first technology – a milestone that highlights how standards-based architecture is reshaping modern BSS/OSS and delivering real value in production environments.
When systems are built around Open APIs from the start, they’re easier to integrate, faster to evolve, and far more resilient in live operations.
We’re proud to share that LINK Mobility has become the latest Cerillion customer to achieve real-world certification for its Open APIs, offering another clear proof point of these benefits playing out at scale.
Six separate Open APIs deployed within LINK’s production environment have now been certified, adding to a growing portfolio of customers with real-world certifications, underlining the maturity and depth of our API-first architecture.
Real-world certifications are a critical benchmark for the industry. They demonstrate not only compliance with TM Forum standards but also the proven use of Open APIs in live customer environments. Unlike product conformance certifications, where vendors validate their APIs in controlled development or test labs, real-world certifications offer tangible proof that Open APIs are embedded within the product, form the core of the solution, and actively support day-to-day operations.
With LINK Mobility now joining our expanding group of certified customers, Cerillion has become the leading BSS/OSS vendor in terms of the number of customers achieving TM Forum real-world certification. This is a direct reflection of our long-standing commitment to delivering solutions built natively on Open APIs rather than retrofitted to them.
For operators and digital service providers, this matters. Open, standards-based integration reduces complexity, accelerates transformation, and ensures long-term interoperability. Our certifications with LINK Mobility reinforce that API-first is a core design principle, proven in live environments across multiple customers.
