Metadata

MetadataAPI

Migration strategy

The Metadata API in Altinn 2 shows which services are available in the solution and metadata about them. In Altinn 3 the concept of “service” will be replaced by the concept of “resources” and the resources will be available in a Resource Administration.

What are the consequences for consumers

This API will remain available, but as services are migrated from Altinn 2 to Altinn 3 you will need to adopt equivalent, new APIs in Altinn 3.
