# ListOpenCypherQueries


Lists active openCypher queries. See [Neptune openCypher status endpoint](https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-opencypher-status.html) for more information.

When invoking this operation in a Neptune cluster that has IAM authentication enabled, the IAM user or role making the request must have a policy attached that allows the [neptune-db:GetQueryStatus](https://docs.aws.amazon.com/neptune/latest/userguide/iam-dp-actions.html#getquerystatus) IAM action in that cluster.

Note that the [neptune-db:QueryLanguage:OpenCypher](https://docs.aws.amazon.com/neptune/latest/userguide/iam-data-condition-keys.html#iam-neptune-condition-keys) IAM condition key can be used in the policy document to restrict the use of openCypher queries (see [Condition keys available in Neptune IAM data-access policy statements](https://docs.aws.amazon.com/neptune/latest/userguide/iam-data-condition-keys.html)).
