#xAPI in the Simplest Data LRS

The Simplest Data LRS stores and retrieves learning activity using xAPI. The xAPI contract belongs to the LRS application and remains consistent across operating models.

#Discover supported versions

Shell

curl -fsS http://127.0.0.1:8000/xAPI/about

The LRS currently advertises 1.0.3 and 2.0.0. Use 2.0.0 for the primary documented path. The About resource does not require an X-Experience-API-Version header. Other /xAPI requests require a supported version header.

#Local / self-managed examples

Examples in this documentation use the Local / self-managed LRS at http://127.0.0.1:8000.

The default local runtime is unauthenticated. See LRS networking before exposing it beyond localhost.
