Replace value

This endpoint replaces the value and the Targeting Rules of a Feature Flag or Setting in a specified Environment identified by the <a target="_blank" rel="noopener noreferrer" href="https://app.configcat.com/sdkkey">SDK key</a> passed in the X-CONFIGCAT-SDKKEY header.

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

Important: As this endpoint is doing a complete replace, it's important to set every other field that you don't want to change to its original state. Not listing one means it will reset.

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

{
  "defaultValue": {
    "boolValue": false
  },
  "targetingRules": [
    {
      "conditions": [
        {
          "userCondition": {
            "comparisonAttribute": "Email",
            "comparator": "sensitiveTextEquals",
            "comparisonValue": {
              "stringValue": "test@example.com"
            }
          }
        }
      ],
      "percentageOptions": [],
      "value": {
        "boolValue": true
      }
    }
  ]
}

If we send a replace request body as below:

{
  "defaultValue": {
    "boolValue": true
  }
}

Then besides that the default served value is set to true, all the Targeting Rules are deleted. So we get a response like this:

{
  "defaultValue": {
    "boolValue": true
  },
  "targetingRules": []
}
