On 23 January 2026, the European Commission closes the consultation on the draft implementing regulation under Regulation (EU) 2024/900 on the transparency and targeting of political advertising. The draft sets out arrangements for the European repository for online political advertisements, including a common data structure, standardised metadata, standardised authentication, and a common application programming interface. It establishes technical requirements for the organisation, management, and retrieval of information in the repository, covering metadata elements, unique value domains, interoperability with advertising repositories under Article 39 of the Digital Services Act, and the transparency database under Article 24(5), as well as compliance with data governance and accessibility standards. The draft further specifies registration and authentication protocols, application programming interface functionalities using SOAP or REST, security requirements for automated data transfers, and obligations for registered users to submit and correct data using unique identifiers.
