Create experiments archive

Archive an ended experiment.

Hides the experiment from the default list view. The experiment can be restored at any time by updating archived=false. When the linked feature flag is still enabled, pass disable_feature_flag=true to also disable and archive it. Returns 400 if the experiment is already archived or has not ended yet.

Create experiments create exposure cohort for experiment

Mixin for ViewSets to handle approval-gate exceptions raised from decorated serializers.

Intercepts ApprovalRequired (409) and PolicyConflict (400) raised by the @approval_gate decorator on serializer methods and converts them into the same responses the viewset path produces (see decorators._result_to_response), so both paths share one contract.

Create experiments end

End a running experiment without shipping a variant.

Sets end_date to now and marks the experiment as stopped. The feature flag is NOT modified — users continue to see their assigned variants and exposure events ($feature_flag_called) continue to be recorded. However, only data up to end_date is included in experiment results.

Use this when:

  • You want to freeze the results window without changing which variant users see.
  • A variant was already shipped manually via the feature flag UI and the experiment just needs to be marked complete.

The end_date can be adjusted after ending via PATCH if it needs to be backdated (e.g. to match when the flag was actually paused).

Other options:

  • Use ship_variant to end the experiment AND roll out a single variant to 100%% of users.
  • Use pause to deactivate the flag without ending the experiment (stops variant assignment but does not freeze results).

Returns 400 if the experiment is not running.

Create experiments freeze exposure

Freeze exposure on a running experiment while metrics keep flowing.

Snapshots the already-exposed users into a static cohort and narrows the linked feature flag so only those users keep matching — new users can no longer enter the experiment. end_date is left null so long-term metrics (revenue/LTV/renewals/retention) keep accumulating. Enrolled users keep their assigned variant. The serialized status becomes 'exposure_frozen'.

Returns 400 if the experiment is not running, exposure is already frozen, the experiment is group-aggregated (group flags cannot be frozen with a person cohort), or the exposed set is too large to snapshot synchronously.

Create experiments launch

Launch a draft experiment.

Validates the experiment is in draft state, activates its linked feature flag, sets start_date to the current server time, and transitions the experiment to running. Returns 400 if the experiment has already been launched or if the feature flag configuration is invalid (e.g. fewer than 2 variants).

Create experiments metrics recalculation

Trigger a batch recalculation of all metrics for this experiment.

Returns 201 with the new pending recalculation, or 200 with the active one if a recalculation is already pending or in progress for this experiment. The response payload intentionally does not include the results array — at POST time the workflow has just been queued and no per-metric results exist yet. Clients should poll GET metrics_recalculation/{id}/ for results as the workflow progresses.

Retrieve experiments metrics recalculation

Mixin for ViewSets to handle approval-gate exceptions raised from decorated serializers.

Intercepts ApprovalRequired (409) and PolicyConflict (400) raised by the @approval_gate decorator on serializer methods and converts them into the same responses the viewset path produces (see decorators._result_to_response), so both paths share one contract.

Create experiments pause

Pause a running experiment.

Deactivates the linked feature flag so it is no longer returned by the /decide endpoint. Users fall back to the application default (typically the control experience), and no new exposure events are recorded (i.e. $feature_flag_called is not fired). Returns 400 if the experiment is not running or is already paused.

Create experiments reset

Reset an experiment back to draft state.

Clears start/end dates, conclusion, and archived flag. The feature flag is left unchanged — users continue to see their assigned variants.

Previously collected events still exist but won't be included in results unless the start date is manually adjusted after re-launch.

Returns 400 if the experiment is already in draft state.

Create experiments resume

Resume a paused experiment.

Reactivates the linked feature flag so it is returned by /decide again. Users are re-bucketed deterministically into the same variants they had before the pause, and exposure tracking resumes. Returns 400 if the experiment is not running or is not paused.
