Update value

PATCH 
/v2/settings/:settingKeyOrId/value

This endpoint updates the value of a Feature Flag or Setting with a collection of JSON Patch operations in a specified Environment.

Only the defaultValue, targetingRules, and percentageEvaluationAttribute fields are modifiable by this endpoint.

The advantage of using JSON Patch is that you can describe individual update operations on a resource without touching attributes that you don't want to change. It supports collection reordering, so it also can be used for reordering the targeting rules of a Feature Flag or Setting.

For example: We have the following resource of a Feature Flag.

{
  "defaultValue": {
    "boolValue": false
  },
  "targetingRules": [
    {
      "conditions": [
        {
          "userCondition": {
            "comparisonAttribute": "Email",
            "comparator": "sensitiveTextEquals",
            "comparisonValue": {
              "stringValue": "[email protected]"
            }
          }
        }
      ],
      "percentageOptions": [],
      "value": {
        "boolValue": true
      }
    }
  ]
}

If we send an update request body as below:

[
  {
    "op": "replace",
    "path": "/targetingRules/0/value/boolValue",
    "value": true
  }
]

Only the first Targeting Rule's value is going to be set to false and all the other fields are remaining unchanged.

So we get a response like this:

{
  "defaultValue": {
    "boolValue": false
  },
  "targetingRules": [
    {
      "conditions": [
        {
          "userCondition": {
            "comparisonAttribute": "Email",
            "comparator": "sensitiveTextEquals",
            "comparisonValue": {
              "stringValue": "[email protected]"
            }
          }
        }
      ],
      "percentageOptions": [],
      "value": {
        "boolValue": false
      }
    }
  ]
}
