Recommended use
This endpoint can return a large amount of information. Specifying one or multiple environments with the
envparameter can decrease response time and overall payload size. We recommend using this parameter to return only the environments relevant to your query.
LaunchDarkly supports the expand query param to include additional fields in the response, with the following fields:
evaluation includes evaluation information within returned environments, including which context kinds the flag has been evaluated for in the past 30 daysmigrationSettings includes migration settings information within the flag and within returned environments. These settings are only included for migration flags, that is, where purpose is migration.For example, expand=evaluation includes the evaluation field in the response.
