Urn → Splits.io

Urn does not support the generic Splits.io Exchange Format, so it cannot output runs in the standard format.

However, Splits.io has limited support for reading Urn's proprietary format. These files use the extension .json.

Splits.io → Urn

Urn doesn't support the Splits.io Exchange Format, so it can't read most runs from Splits.io.

However, Splits.io can try to export runs in Urn format. Look for the "Urn" option when exporting a run from Splits.io.

You can request runs from the API in Urn format using this header:

Accept: application/urn

Runs returned in Urn format include the header:

Content-Type: application/urn
