Return value

Parameter and Type	Child Attribute	Description

Example Return Value

["6661191859", "6666781105", "7555673865"]

Description

Get an array of experiment IDs that are currently active on the page for the visitor. If the visitor is excluded from an experiment due to traffic allocation, the experiment is considered active and they will be bucketed into a variation, but no visual changes will be applied. This situation is referred to as isInExperimentHoldback in the getExperimentStates API:

state.getExperimentStates()[{experiment_id}].isInExperimentHoldback

getRedirectInfo()

If a redirect variation was executed on the previous page, all the details of that experiment are accessible on the next page through the getRedirectInfo() function.

Syntax

state.getRedirectInfo();

Return value

Parameter and Type	Child Attribute	Description
null or RedirectInfoObject	N/A	The object contains all the details about a redirect experiment that ran on the previous page.
experimentId string	Child attribute of type RedirectInfoObject	The ID of the redirect experiment. Required.
variationId string	Child attribute of type RedirectInfoObject	The ID of the redirect variation. Required.

  "referrer": "https://www.google.com/"
}

Description

If a redirect variation was executed on the previous page, all the details of that experiment are accessible on the next page through the getRedirectInfo() function. Most analytics integrations use this information to correct referrer values.

getDecisionString()

Get a single string describing the campaign/experiment decision for a given campaign ID.

Syntax

state.getDecisionString(config);

Parameters

Parameters and Type	Child Attribute	Description
config DecisionConfigObject	N/A	An object with configuration fields for the function. Required.
campaignId string	Child attribute of type DecisionConfigObject	Indicates the campaign to get the decision string for. Required.
shouldCleanString Boolean	Child attribute of type DecisionConfigObject	If true, any character that matches the regex `/[^a-zA-Z0-9\.\~\!\*\(\)\']+/g` is replaced with `_`. Default is false.
maxLength number	Child attribute of type DecisionConfigObject	The maximum length of the returned string. If the combined length of names and IDs is longer than the maxLength, the names will be individually truncated, with favor given to the campaign name. Default is 255 characters.

Return value

Parameter and Type	Child Attribute	Description
string	N/A	For personalization campaign decisions, the string returned is a concatenation of the decision campaign, experiment, and variation names and IDs, and holdback status. For A/B experiment decisions, the string returned is a concatenation of the decision experiment and variation names and IDs. More details on naming conventions for third-party integrations.

Example Call

state.getDecisionString({
  "campaignId": "6676370413"
});

Example Return Value

"Example personalization campaign(6676370413):Example experiment(6666781105):Variation #1(6626731852):holdback"

Description

Get a single string describing the campaign/experiment decision for a given campaign ID. This is often used to send campaign decision data to third-party analytics integrations. This function takes a campaign ID as a parameter; if the campaign in question is an AB test, make sure to still pass the campaign ID, and this API will return only the information that is relevant to an A/B test. This makes it so that code consuming this API does not have to conditionalize on whether the decision is for an AB test or a personalization campaign.

getDecisionObject()

Get an object with strings that describe the campaign/experiment decision for a given campaign ID.

Syntax

state.getDecisionObject(config);

Parameters

Parameter and Type	Child Attribute	Description
config DecisionConfigObject	N/A	An object with configuration fields for the function. Required.
campaignId string	Child attribute of type DecisionConfigObject	Indicates the campaign to get the decision string for. Required.
shouldCleanString Boolean	Child attribute of type DecisionConfigObject	If true, any character that matches the regex `/[^a-zA-Z0-9\.\~\!\*\(\)\']+/g` is replaced with `_`. Default is false.
maxLength number	Child attribute of type DecisionConfigObject	The maximum length of the returned string. If the combined length of names and IDs is longer than the maxLength, the names will be individually truncated, with favor given to the campaign name. Default is 255 characters.

Return value

Parameter and Type	Child attribute	Description
GetDecisionObjectReturn	N/A	For personalization campaign decisions, the object returned contains values for the decision campaign, experiment, and variation names and IDs, and holdback status. For A/B experiment decisions, the object returned contains values for the decision experiment and variation names and IDs.
campaign string or undefined	Child attribute of type GetDecisionObjectReturn	A string representing the decision's campaign name and ID. Not included if campaign is an AB test.
experiment string	Child attribute of type GetDecisionObjectReturn	A string representing the decision's experiment name and ID.
variation string	Child attribute of type GetDecisionObjectReturn	A string representing the decision's variation name and ID.

  "campaignId": "6676370413"
});

Example Return Value

{
  "campaign": "Shopping Cart (6676370413)",
  "experiment": "New Visitors (3243212353)",
  "variation": "Variation #1 (2344343121)",
  "holdback": false
}

Description

Get an object with strings that describe the campaign/experiment decision for a given campaign ID. This is often used to send campaign decision data to third-party analytics integrations. This function takes a campaign ID as a parameter; if the campaign in question is an AB test, make sure to still pass the campaign ID, and this API will return only the information that is relevant to an A/B test.
