Browser to segment results by. This parameter must not be sent with any other segmentation parameters, i.e. any parameters in [device, source, attribute_id, attribute_value].

Device to segment results by. This parameter must not be sent with any other segmentation parameters, i.e. any parameters in [browser, source, attribute_id, attribute_value].

Source to segment results by. This parameter must not be sent with any other segmentation parameters, i.e. any parameters in [browser, device, attribute_id, attribute_value]. Campaign: Contains users that arrive on a URL containing a 'utm_campaign,' 'utm_source,' 'gclid,' or 'otm_source' query parameter. If the URL contains one of these parameters, the visitor will count as "Campaign" traffic even if they arrived through search. Direct: Includes all users who do not have any external referrer in their URL. Referral: Includes all users that come from another URL that doesn't count as Campaign.

ID of the attribute to segment results by. Requests containing attribute_id will return the results for all visitors that have attribute_value for the attribute represented by attribute_id. If present, the attribute_value parameter must also be present, and it cannot be sent with any other segmentation parameters, i.e. any parameters in [browser, device, source].

UTF-8 encoded value correlating to attribute_id. If present, the attribute_id parameter must also be present. This parameter also requires attribute_id to be set, and cannot be sent with any other segmentation parameters, i.e. any parameters in [browser, device, source].

(BETA) A string representation of a JSON Segment Conditions Expression. This parameter can be either URL-escaped stringified JSON or Base64-encoded stringified JSON using URL-safe alphabet (preferred). Segment Conditions Expressions consist of Logical Expressions and Match Expressions. Logical Expressions are represented as an array of the format [<operator>, <expression>...], where the supported operators are "and", "or" and "not". Match Expressions are represented as an object of the format {"attribute_id": <attribute_id>, "attribute_value": <value>[, "match_type": <match_type>]}, where supported values for match_type are "exact" match type will match only an exact string match between "value" string and the attribute value. "substring" match type will match if "value" is a substring of the attribute value. "prefix" match type will match if "value" is a string prefix of the attribute value. "regex" match type will match if "value" is a regular expression match for the attribute value. The default match_type is "exact".
