# List the versions of a Scenario `ListScenarioVersions` `GET /api/scenarios/{scope}/{code}/versions` - [OpenAPI fragment](https://www.lusid.com/docs/api/lusid/endpoints/scenarios/ListScenarioVersions.json) - [Rendered page](https://www.lusid.com/docs/api/lusid/endpoints/scenarios/ListScenarioVersions) List the AsAt versions of a single Scenario definition, newest first: one entry per change, with the version number, the AsAt datetime it was written, and the user that wrote it. Scenarios are perpetual (AsAt-only), so a version's AsAt datetime identifies it completely: pass it as the asAt on GetScenario to view that version, or as the scenario reference's asAt on a valuation to price under it. ## Referenced schemas - [PagedResourceListOfVersion](https://www.lusid.com/docs/api/lusid/schemas/PagedResourceListOfVersion.txt) [< Scenarios](https://www.lusid.com/docs/api/lusid/endpoints/scenarios/llms.txt)
