apidays Paris 2026 will take place from 1 to 3 December 2026 at CNIT Forest in Paris, France. The event is the Paris edition of apidays, a long-running international conference series focused on APIs, held for more than 12 years. In 2026, the organisers place artificial intelligence at the centre of the programme, but with a specific angle: sovereignty, resilience and operational continuity.
The event is framed around the idea of the “Sovereign autonomous API Stack.” According to the conference description, apidays Paris 2026 responds to a digital environment that is increasingly “agent-orchestrated,” where AI agents act autonomously through APIs. The event’s main concern is how to build such systems without depending on foreign cloud infrastructure or opaque external services. Topics highlighted include local infrastructure, regional data residency, security, governance, API management, AI-driven automation, sustainability and emerging technology trends.
The audience is broad but clearly technical and strategic: developers, API architects, technology decision-makers, and business leaders. The programme is designed to combine practical implementation with strategic debate. It includes hands-on workshops, real-world case studies, and a large speaker programme. The event advertises more than 300 sessions and 300 speakers, with around 4,000 participants and 1,500 companies expected.
apidays Paris 2026 is also organised as a multi-event format. Alongside the main conference, ticket holders gain access to partner events including Hacking APIs Conference Paris, GenerationAI Paris and Green IO Paris. This structure suggests a wider focus on the technical, security and environmental dimensions of digital infrastructure.
Among the speakers mentioned on the page is Nat Sakimura, chairman of the OpenID Foundation and a well-known identity and privacy standards expert. That points to the event’s interest in identity, trust and standards as core building blocks of AI-enabled public and private services.
