Stancer

Stancer is a French API-first payment platform backed by Iliad, the telecommunications group behind Free. Designed as a native European alternative to US payment processors, it offers competitive transaction rates, card tokenisation, and online checkout integration with GDPR compliance built in by design.

The Stancer API supports TLS 1.2 and HTTP/2, with libraries for major languages and full documentation for custom integrations. Card-on-file tokenisation enables recurring and subscription billing without merchants storing raw card data, while a physical Verifone terminal option extends the same API experience to in-store payments.

Key benefits:

• Card tokenisation for recurring billing without storing sensitive card data
• Developer API with TLS 1.2, HTTP/2, and multi-language SDKs
• Recurring and subscription billing via card-on-file tokens
• In-store terminal support alongside the online API
• GDPR-native compliance with European data residency by default
• Competitive pricing as a direct European alternative to US processors

Stancer is headquartered in France and built entirely within the EU, offering European data residency as a core feature. As a subsidiary of the French group Iliad, it operates under Banque de France oversight and PCI DSS compliance — a privacy-first payment infrastructure for European developers.
