Table 1. Parameters
Parameter		Required	Description
Headers	`Authorization`	Yes	Information about authentication access token in format "Bearer `<accessToken>`" (see details in Authentication API).
Query	`select`	No	Comma-separated list of properties from the entity structure that should be returned in a response. Allows you to return a partial object. This parameter can be used to include the following fields: entity label (using the `label` keyword) entity secondaryLabel (using the `secondaryLabel` keyword) entity or relation attributes (prefixing `entities` or `relations` before the `attributes` keyword) Note: The `select` parameter supports all attributes. The following query returns data for all fields: `select=label,secondaryLabel,entities.attributes,relations.attributes` Note: Data is also returned for all fields if the `select` parameter is not used in the request.
	`graphTypeURIs`	No	Comma-separated list of graph types URIs for graphs to be traversed. For more information, see Configuring Graph Types.
	`relationTypeURIs`	No	Comma-separated list of relation type URIs (see details in Relation Types) for relation to be traversed.
	`entityTypeURIs`	No	Comma-separated list of entity type URIs (see details in Entity Types) for relation to be traversed.
	`deep`	No	Limits traversing deep levels. Default is `1`.
	`max`	No	Limits the amount of entities to be returned from the API. If the number of entities does not fit into the specified level, then only entities from previous levels are returned.
	`returnInactive`	No	Flag to traverse inactive entities/relationships Default is `false`.
	`filterLastLevel`	No	Flag to NOT count relationships from the last level of deep to the next level after the last. In a response it affects these entity parameters: `untraversedRelationsCount` and `traversedRelationsCount`. Default is `true`.
	`options`	No	Comma-separated list of different options which affect entity's JSON content in the response. Available options: `sendHidden`: disabled by default; entity's JSON contains hidden attributes if this option is enabled. `ovOnly`: return only attribute values that have the `ov=true` flag. `nonOvOnly`: return only attribute values that have the `ov=false` flag. If you have a nested or reference attribute value, where `ov=true`, but sub-attributes, where `ov=false`, then these sub-attributes will not appear in the response.
