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

This endpoint removes a Feature Flag or Setting from a specified Config, identified by the configId parameter.

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

Only the name, hint and tags attributes are modifiable by this endpoint. The tags attribute is a simple collection of the tag IDs attached to the given setting.

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.

For example: We have the following resource.

{
  "settingId": 5345,
  "key": "myGrandFeature",
  "name": "Tihs is a naem with soem typos.",
  "hint": "This flag controls my grandioso feature.",
  "settingType": "boolean",
  "tags": [
    {
      "tagId": 0, 
      "name": "sample tag", 
      "color": "whale"
    }
  ]
}

If we send an update request body as below (it changes the name and adds the already existing tag with the id 2):

[
  {
    "op": "replace", 
    "path": "/name", 
    "value": "This is the name without typos."
  }, 
  {
    "op": "add", 
    "path": "/tags/-", 
    "value": 2
  }
]

Only the name and tags are updated and all the other attributes remain unchanged. So we get a response like this:

{
  "settingId": 5345, 
  "key": "myGrandFeature", 
  "name": "This is the name without typos.", 
  "hint": "This flag controls my grandioso feature.", 
  "settingType": "boolean", 
  "tags": [
    {
      "tagId": 0, 
      "name": "sample tag", 
      "color": "whale"
    }, 
    {
      "tagId": 2, 
      "name": "another tag", 
      "color": "koala"
    }
  ]
}

This endpoint returns the list of the Settings that has the specified Tag, identified by the tagId parameter.

This endpoint returns the value of a Feature Flag or Setting in a specified Environment identified by the environmentId parameter.

The most important attributes in the response are the value, rolloutRules and percentageRules. The value represents what the clients will get when the evaluation requests of our SDKs are not matching to any of the defined Targeting or Percentage Rules, or when there are no additional rules to evaluate.

The rolloutRules and percentageRules attributes are representing the current Targeting and Percentage Rules configuration of the actual Feature Flag or Setting in an ordered collection, which means the order of the returned rules is matching to the evaluation order. You can read more about these rules here.

This endpoint replaces the whole value of a Feature Flag or Setting in a specified Environment.

Only the value, rolloutRules and percentageRules attributes are modifiable by this endpoint.

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

For example: We have the following resource.

{
  "rolloutPercentageItems": [
    {
      "percentage": 30,
      "value": true
    },
    {
      "percentage": 70,
      "value": false
    }
  ],
  "rolloutRules": [],
  "value": false
}

If we send a replace request body as below:

{
  "value": true
}

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

{
  "rolloutPercentageItems": [],
  "rolloutRules": [],
  "value": true
}

The rolloutRules property describes two types of rules:

• Targeting rules: When you want to add or update a targeting rule, the comparator, comparisonAttribute, and comparisonValue members are required.

• Segment rules: When you want to add add or update a segment rule, the segmentId which identifies the desired segment and the segmentComparator members are required.

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

Only the value, rolloutRules and percentageRules attributes 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.

{
  "rolloutPercentageItems": [
    {
      "percentage": 30,
      "value": true
    },
    {
      "percentage": 70,
      "value": false
    }
  ],
  "rolloutRules": [],
  "value": false
}

If we send an update request body as below:

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

Only the default value is going to be set to true and all the Percentage Rules are remaining unchanged. So we get a response like this:

{
  "rolloutPercentageItems": [
    {
      "percentage": 30,
      "value": true
    },
    {
      "percentage": 70,
      "value": false
    }
  ],
  "rolloutRules": [],
  "value": true
}

The rolloutRules property describes two types of rules:

• Targeting rules: When you want to add or update a targeting rule, the comparator, comparisonAttribute, and comparisonValue members are required.

• Segment rules: When you want to add add or update a segment rule, the segmentId which identifies the desired segment and the segmentComparator members are required.

This endpoint returns the value of a Feature Flag or Setting in a specified Environment identified by the environmentId parameter.

The most important fields in the response are the defaultValue, targetingRules, and percentageEvaluationAttribute. The defaultValue represents what the clients will get when the evaluation requests of our SDKs are not matching to any of the defined Targeting Rules, or when there are no additional rules to evaluate.

The targetingRules represents the current Targeting Rule configuration of the actual Feature Flag or Setting in an ordered collection, which means the order of the returned rules is matching to the evaluation order. You can read more about these rules here.

The percentageEvaluationAttribute represents the custom User Object attribute that must be used for percentage evaluation of the Feature Flag or Setting.

This endpoint replaces the value and the Targeting Rules of a Feature Flag or Setting in a specified Environment identified by the SDK key 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": []
}

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.

            "comparator": "sensitiveTextEquals",
            "comparisonValue": {
              "stringValue": "test@example.com"
            }
          }
        }
      ],
      "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": {

      ],
      "percentageOptions": [],
      "value": {
        "boolValue": false
      }
    }
  ]
}

This endpoint returns the value of a specified Config's Feature Flags or Settings identified by the configId parameter in a specified Environment identified by the environmentId parameter.

The most important attributes in the response are the value, rolloutRules and percentageRules. The value represents what the clients will get when the evaluation requests of our SDKs are not matching to any of the defined Targeting or Percentage Rules, or when there are no additional rules to evaluate.

The rolloutRules and percentageRules attributes are representing the current Targeting and Percentage Rules configuration of the actual Feature Flag or Setting in an ordered collection, which means the order of the returned rules is matching to the evaluation order. You can read more about these rules here.

This endpoint replaces the values of a specified Config's Feature Flags or Settings identified by the configId parameter in a specified Environment identified by the environmentId parameter.

Only the value, rolloutRules and percentageRules attributes are modifiable by this endpoint.

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

For example: We have the following resource.

{
  "settingValues": [
    {
      "rolloutPercentageItems": [
        {
          "percentage": 30,

      ],
      "rolloutRules": [],
      "value": false,
      "settingId": 1
    }
  ]
}

If we send a replace request body as below:

{ 
  "settingValues": [
    {
      "value": true,
      "settingId": 1
    }
  ]
}

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

{

    {
      "rolloutPercentageItems": [],
      "rolloutRules": [],
      "value": true,
      "setting": 
      {
        "settingId": 1
      }
    }
  ]
}

The rolloutRules property describes two types of rules:

• Targeting rules: When you want to add or update a targeting rule, the comparator, comparisonAttribute, and comparisonValue members are required.

• Segment rules: When you want to add add or update a segment rule, the segmentId which identifies the desired segment and the segmentComparator members are required.

This endpoint returns all Feature Flag and Setting values of a Config identified by the configId parameter in a specified Environment identified by the environmentId parameter.

The most important fields in the response are the defaultValue, targetingRules. The defaultValue represents what the clients will get when the evaluation requests of our SDKs are not matching to any of the defined Targeting Rules, or when there are no additional rules to evaluate.

The targetingRules represents the current Targeting Rule configuration of the actual Feature Flag or Setting in an ordered collection, which means the order of the returned rules is matching to the evaluation order. You can read more about these rules here.

The percentageEvaluationAttribute represents the custom User Object attribute that must be used for percentage evaluation of the Feature Flag or Setting.

This endpoint batch updates the Feature Flags and Settings of a Config identified by the configId parameter in a specified Environment identified by the environmentId parameter.

Only those Feature Flags and Settings are updated which are part of the request, all the others are left untouched.

Important: As this endpoint is doing a complete replace on those Feature Flags and Settings, which are set in the request. It's important to set every other field that you don't want to change in its original state. Not listing a field means that it will reset.

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

{
  "settingFormulas": [
    {
      "defaultValue": {
        "boolValue": false
      },
      "targetingRules": [
        {
          "conditions": [
            {
              "userCondition": {
                "comparisonAttribute": "Email",

                  "stringValue": "test@example.com"
                }
              }
            }
          ],
          "percentageOptions": [],
          "value": {
            "boolValue": true
          }
        }
      ],
      "settingId": 1
    }
  ]
}

If we send a batch replace request body as below:

{ 
  "updateFormulas": [
    {
      "defaultValue": {
        "boolValue": false
      },
      "settingId": 1
    }
  ]
}

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

{
  "settingFormulas": [
    {
      "defaultValue": {
        "boolValue": false
      },
      "targetingRules": [],
      "setting":

        "settingId": 1
      }
    }
  ]
}

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

This endpoint removes a Webhook identified by the webhookId parameter.

This endpoint updates a Webhook identified by the webhookId parameter with a collection of JSON Patch operations.

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.

For example: We have the following resource.

{
  "webhookId": 6,
  "url": "https://example.com/hook",
  "httpMethod": "post",
  "content": "null",
  "webHookHeaders": []
}

If we send an update request body as below (it changes the content field and adds a new HTTP header):

[
  {
    "op": "replace", 
    "path": "/content", 
    "value": "Some webhook content."
  }, 
  {
    "op": "add", 
    "path": "/webHookHeaders/-", 
    "value": {
      "key": "X-Custom-Header", 
      "value": "Custom header value"
    }
  }
]

Only the content and webHookHeaders are updated and all the other attributes remain unchanged. So we get a response like this:

{
  "webhookId": 6,
  "url": "https://example.com/hook",
  "httpMethod": "post",
