Dataset description

HMRC has developed an open data strategy, a detailed document laying out plans to publish information in a linkable and re-usable format with the aim to drive reform and improvement through transparency and citizen participation. (See 'Additional links') As part of this initiative, the Department has also released the Data Catalogue, an initial inventory of the datasets HMRC holds and processes. The catalogue is a refresh of the information released in the transparency implementation plan.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
