xAPI Versioning
SQL LRS supports xAPI versions 1.0.3 and 2.0.0. The version used is determined by the X-Experience-API-Version header in the request. Use the LRSQLSUPPORTEDVERSIONS environment variable or the supportedVersions LRS configuration property to set which versions are supported. By default, both versions are supported. For more information see the configuration documentation.
Strict Versioning
Note that by default, responses to requests with an X-Experience-API-Version header set to 1.0.3 may contain statements in 2.0.0 format. To ensure that 2.0.0 statements are downgraded to 1.0.3 format use the LRSQL_ENABLE_STRICT_VERSION environment variable or the enableStrictVersion LRS configuration property. For more information see the configuration documentation.
Reaction Versioning
Reactions generate version 1.0.3 statements by default but you can configure this by setting the LRSQL_REACTION_VERSION environment variable or the reactionVersion LRS configuration property. For more information see the configuration documentation. Note that creating reactions under 2.0.0 and then restricting the LRS to version 1.0.3 only will lead to errors in the LRS Admin UI frontend. To recover from this situation reenable 2.0.0 support and delete any incompatible reactions before returning to 1.0.3 only.
