Patch experiment

Update an experiment. Updating an experiment uses the semantic patch format. To make a semantic patch request, you must append `domain-model=launchdarkly.semanticpatch` to your `Content-Type` header. To learn more, read [Updates using semantic patch](https://launchdarkly.com/docs/api#updates-using-semantic-patch). ### Instructions Semantic patch requests support the following `kind` instructions for updating experiments. #### updateName Updates the experiment name. ##### Parameters - `value`: The new name. Here's an example: ```json { "instructions": [{ "kind": "updateName", "value": "Example updated experiment name" }] } ``` #### updateDescription Updates the experiment description. ##### Parameters - `value`: The new description. Here's an example: ```json { "instructions": [{ "kind": "updateDescription", "value": "Example updated description" }] } ``` #### startIteration Starts a new iteration for this experiment. You must [create a new iteration](https://launchdarkly.com/docs/api/experiments/create-iteration) before calling this instruction. An iteration may not be started until it meets the following criteria: * Its associated flag is toggled on and is not archived * Its `randomizationUnit` is set * At least one of its `treatments` has a non-zero `allocationPercent` ##### Parameters - `changeJustification`: The reason for starting a new iteration. Required when you call `startIteration` on an already running experiment, otherwise optional. Here's an example: ```json { "instructions": [{ "kind": "startIteration", "changeJustification": "It's time to start a new iteration" }] } ``` #### stopIteration Stops the current iteration for this experiment. ##### Parameters - `winningTreatmentId`: The ID of the winning treatment. Treatment IDs are returned as part of the [Get experiment](https://launchdarkly.com/docs/api/experiments/get-experiment) response. They are the `_id` of each element in the `treatments` array. - `winningReason`: The reason for the winner Here's an example: ```json { "instructions": [{ "kind": "stopIteration", "winningTreatmentId": "3a548ec2-72ac-4e59-8518-5c24f5609ccf", "winningReason": "Example reason to stop the iteration" }] } ``` #### archiveExperiment Archives this experiment. Archived experiments are hidden by default in the LaunchDarkly user interface. You cannot start new iterations for archived experiments. Here's an example: ```json { "instructions": [{ "kind": "archiveExperiment" }] } ``` #### restoreExperiment Restores an archived experiment. After restoring an experiment, you can start new iterations for it again. Here's an example: ```json { "instructions": [{ "kind": "restoreExperiment" }] } ```
