Experiment Variants

Manage variants on a parent experiment. Each variant is either a redirect (sends matched visitors to a new URL) or a dom_modifications set (declarative on-page mutations). Variants only mutate while the parent experiment is in draft status — once running, the variant set is locked.

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

experimentId*string

Parent experiment ID that will own this new variant.

Length1 <= length

name*string

Human-readable name for the new variant.

weight*integer

Traffic weight to assign to this variant. Weights are relative shares; the runtime normalizes by their sum. Must be a positive integer in the range 1..1_000_000.

Range1 <= value <= 1000000

variantType?|

Variant type to create. Use redirect for redirect tests or dom_modifications for on-page changes.

Value in"dom_modifications" | "redirect"

redirectUrl?|

Required for redirect variants. Use either a site-relative path such as /pricing-v2 or an absolute https:// URL. Cross-origin http:// URLs are rejected. Omit for DOM modification variants.

domModifications?array<>|

Required for DOM modification variants. Omit for redirect variants. Each entry is {selector, action, value}.

isControl?|

Mark this variant as the experiment control. Defaults to false. The API rejects the request with 409 if the experiment already has a control variant — to swap controls, first PATCH the existing control to clear isControl, then create or PATCH the new one with isControl: true. The auto-generated control variant created with each new experiment can be replaced this way. DELETE on the control returns 409.

Path Parameters

id*string

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

name?|

Updated variant name.

weight?|

Updated traffic weight relative to other variants. Must be a positive integer in the range 1..1_000_000.

Range1 <= value <= 1000000

variantType?|

Updated variant type — redirect or dom_modifications. Changing this also requires updating the matching payload field (redirectUrl or domModifications).

Value in"dom_modifications" | "redirect"

redirectUrl?|

Updated redirect URL for redirect variants. Use either a site-relative path such as /pricing-v2 or an absolute https:// URL. Cross-origin http:// URLs are rejected.

domModifications?array<>|

Updated declarative DOM mutations. Sending this field replaces the prior list — partial-array merging is not supported.

isControl?|

Promote or demote this variant as the control. Promoting a second variant while another already has isControl: true is rejected with 409 — clear the existing control first.
