Commission Delegated Regulation (EU) 2025/645 of 1 April 2025 supplementing Regulation (EU) 2023/1804 of the European Parliament and of the Council as regards common technical requirements for a common application programme interface

1 An application programme interface (API) referred to in Article 20(3) of Regulation (EU) 2023/1804 shall comply with the following common technical requirements: (a) it shall be technically compatible, where relevant, with recharging and refuelling points for alternative fuels software management systems and national access points; (b) it shall facilitate usability for data users in order to support the development of high-quality information services on alternative fuels; (c) it shall be scalable and capable of handling growing amounts of real-time data over time; (d) it shall be robust and be able to cope with errors during execution; (e) it shall be secure and include relevant protection measures to prevent unintended access to data; (f) it shall undergo regular testing and validation to ensure continued compatibility and reliability; (g) it shall be scalable to support integration in a dedicated web portal of a common European access point to function as a data gateway facilitating the access to data referred to in Article 20(2) of Regulation (EU) 2023/1804.

2 Where operators of publicly accessible recharging points and refuelling points or, in accordance with the arrangements between them, the owners of those points rely on a protocol solution for the API referred to in Article 20(3) of Regulation (EU) 2023/1804, developed by another market actor or third-party provider, they shall ensure, in addition to paragraph 1, that such protocol solution complies with the following common technical requirements: (a) it shall contain a detailed and publicly accessible technical development plan with transparent schedules to inform technical implementation and continuity over time; (b) it shall provide up-to-date publicly accessible documentation and guidelines for seamless integration and usage by data users; (c) it shall provide comprehensive training and technical support to data users to facilitate the successful development and implementation of information services; (d) it shall be technically compatible, where relevant, with the architecture requirements of the national access points (NAPs); (e) it shall be scalable with a view to integration in a dedicated web portal of a common European access point for alternative fuels data.

3 Where at the date of entry into force of this Regulation, Member States have already prescribed the use of a specific API based on national technical requirements in their territory, such national technical requirements for the API shall apply only in so far as they comply with this Regulation.

This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union. It shall apply from 14 April 2025.
