counts as a breaking change — see API Versioning.
08-07-2026 (v3.0.0)Initial release of major version v3. v3 is now the current major version

This release introduces breaking changes for two Core Resources endpoints:

GET /consent(list consents) - End Users:
GET /end-users(list end users)
Banking and Energy endpoints are unchanged from v2.
New in v3: cursor-based pagination (page[before], page[after],
page[size]) and a links object on the consents and end-users list
responses.
