Feature flags

The feature flags API allows you to list, create, modify, and delete feature flags, their statuses, and their expiring targets programmatically.

Anatomy of a feature flag

The feature flag API allows you to control percentage rollouts, target specific contexts, or even toggle off a feature programmatically. By looking at the representation of a feature flag, we can see how to do any of these tasks.

Sample feature flag representation

Every feature flag has a set of top-level attributes, as well as an environments map containing the flag rollout and targeting rules specific to each environment. Top-level attributes include things like the flag's name, description, tags, and creation date. To learn more, read Using feature flags.

For reference, here's a complete feature flag representation. Below we break this down and explain each attribute in detail.

Top-level attributes

Most of the top-level attributes have a straightforward interpretation. For example, to change the name of a feature, update the feature flag with the name attribute set to the new name:

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

The variations array represents the different variation values that a feature flag has. For a boolean flag, there are two variations: true and false. Multivariate flags have more variation values, and those values could be any JSON type: numbers, strings, objects, or arrays. In targeting rules, the variations are referred to by their index into this array. Below are some specific examples.

Per-environment configurations

Each entry in the environments map contains a JSON object that represents the environment-specific flag configuration data available in the flag's Targeting tab. For example, to toggle off a feature flag in your production environment, use the following JSON patch operation:

[
    { "op": "replace", "path": "/environments/production/on", "value": false }
]

To learn more, read Targeting contexts.

Each section of the Targeting tab corresponds to a different attribute of the per-environment configuration data, as shown here:

Individual context targets

The targets array in the per-environment configuration data represents the individual context targeting rules on the Targeting tab. To learn more, read Targeting contexts.

Each object in the targets array represents a list of context keys assigned to a particular variation. For example:

{
    ...
    "environments" : {
        "production" : {
            ...
            "targets": [
                {
                    "values": ["sandy@example.com"],
                    "variation": 0
                }
            ]
        }
    }
}

This targets array here means that any context instance with the key sandy@example.com receives the first variation listed in the variations array. Recall that the variations are stored at the top level of the flag JSON in an array, and the per-environment configuration rules point to indexes into this array. If this is a boolean flag, sandy@example.com is receiving the true variation.

Targeting rules

The rules array corresponds to the custom targeting rules section of the Targeting tab. This is where you can express complex rules on attributes with conditions and operators. For example, a rule like "roll out the true variation to 80% of contexts whose email address ends with gmail.com could be expressed here. To learn more, read Creating targeting rules.

The fallthrough rule

The fallthrough object is a special rule that contains no conditions. It is the rollout strategy that is applied when none of the individual or custom targeting rules match. In the LaunchDarkly UI, it is called the "Default rule."

The off variation

The off variation represents the variation to serve if the feature flag is turned off, meaning the on attribute is false. For boolean flags, this is usually false. For multivariate flags, set the off variation to whatever variation represents the control or baseline behavior for your application. If you don't set the off variation, LaunchDarkly will serve the fallback value defined in your code.

Percentage rollouts

The weight attribute defines the percentage rollout for each variation. Weights range from 0 (a 0% rollout) to 100000 (a 100% rollout). The weights are scaled by a factor of 1000 so that fractions of a percent can be represented without using floating-point. For example, a weight of 50000 means that 50% of contexts that don't otherwise match any targets will receive that variation. The sum of weights across all variations should be 100%.

List feature flags
Get a list of all features in the given project. By default, each feature includes configurations for each environment. You can filter environments with the env query parameter. For example, setting env=production restricts the returned configurations to just your production environment. You can also filter feature flags by tag with the tag query parameter.


Filtering flags


You can filter on certain fields using the filter query parameter. For example, setting filter=query:dark-mode,tags:beta+test matches flags with the string dark-mode in their key or name, ignoring case, which also have the tags beta and test.


The filter query parameter supports the following arguments:


    

  • query is a string that matches against the flags' keys and names. It is not case sensitive.
    • 

  • archived is a boolean with values of true or false that filters the list to archived flags. Setting the value to true returns only archived flags. When this is absent, only unarchived flags are returned.
    • 

  • type is a string allowing filtering to temporary or permanent flags.
    • 

  • status is a string allowing filtering to new, inactive, active, or launched flags in the specified environment. This filter also requires a filterEnv field to be set to a valid environment. For example: filter=status:active,filterEnv:production.
    • 

  • tags is a + separated list of tags. It filters the list to members who have all of the tags in the list. For example: filter=tags:beta+test.
    • 

  • hasExperiment is a boolean with values of true or false that returns any flags that are used in an experiment.
    • 

  • hasDataExport is a boolean with values of true or false that returns any flags that are exporting data in the specified environment. This includes flags that are exporting data from Experimentation. This filter also requires that you set a filterEnv field to a valid environment key. For example: filter=hasDataExport:true,filterEnv:production
    • 

  • evaluated is an object that contains a key of after and a value in Unix time in milliseconds. This returns all flags that have been evaluated since the time you specify in the environment provided. This filter also requires you to set a filterEnv field to a valid environment. For example: filter=evaluated:{"after": 1590768455282},filterEnv:production.
    • 

  • filterEnv is a string with the key of a valid environment. You can use the filterEnv field for filters that are environment-specific. If there are multiple environment-specific filters, you should only declare this parameter once. For example: filter=evaluated:{"after": 1590768455282},filterEnv:production,status:active.
    • 



By default, this returns all flags. You can page through the list with the limit parameter and by following the first, prev, next, and last links in the returned _links field. These links will not be present if the pages they refer to don't exist. For example, the first and prev links will be missing from the response on the first page.


Sorting flags


You can sort flags based on the following fields:


    

  • creationDate sorts by the creation date of the flag.
    • 

  • key sorts by the key of the flag.
    • 

  • maintainerId sorts by the flag maintainer.
    • 

  • name sorts by flag name.
    • 

  • tags sorts by tags.
    • 

  • targetingModifiedDate sorts by the date that the flag's targeting rules were last modified in a given environment. It must be used with env parameter and it can not be combined with any other sort. If multiple env values are provided, it will perform sort using the first one. For example, sort=-targetingModifiedDate&env=production&env=staging returns results sorted by targetingModifiedDate for the production environment.
    • 

  • type sorts by flag type
    • 



All fields are sorted in ascending order by default. To sort in descending order, prefix the field with a dash ( - ). For example, sort=-name sorts the response by flag name in descending order.

Update feature flag
Perform a partial update to a feature flag. The request body must be a valid semantic patch or JSON patch.


Using semantic patches on a feature flag


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.


The body of a semantic patch request for updating feature flags takes the following properties:


    

  • comment (string): (Optional) A description of the update.
    • 

  • environmentKey (string): (Required for some instructions only) The key of the LaunchDarkly environment.
    • 

  • instructions (array): (Required) A list of actions the update should perform. Each action in the list must be an object with a kind property that indicates the instruction. If the action requires parameters, you must include those parameters as additional fields in the object. The body of a single semantic patch can contain many different instructions.
    • 



Instructions


Semantic patch requests support the following kind instructions for updating feature flags.



Click to expand instructions for turning flags on and off


These instructions require the environmentKey parameter.


turnFlagOff


Sets the flag's targeting state to Off.


Use this request body:


{
  "environmentKey": "environment-key-123abc",
  "instructions": [ { "kind": "turnFlagOff" } ]
}



turnFlagOn


Sets the flag's targeting state to On.


Use this request body:


{
  "environmentKey": "environment-key-123abc",
  "instructions": [ { "kind": "turnFlagOn" } ]
}








Click to expand instructions for working with targeting and variations


These instructions require the environmentKey parameter.


Several of the instructions for working with targeting and variations require flag rule IDs, variation IDs, or clause IDs as parameters. Each of these are returned as part of the Get feature flag response. The flag rule ID is the _id field of each element in the rules array within each environment listed in the environments object. The variation ID is the _id field in each element of the variations array. The clause ID is the _id field of each element of the clauses array within the rules array within each environment listed in the environments object.


addClauses


Adds the given clauses to the rule indicated by ruleId.


Parameters


    

  • ruleId: ID of a rule in the flag.
    • 

  • clauses: Array of clause objects, with contextKind (string), attribute (string), op (string), negate (boolean), and values (array of strings, numbers, or dates) properties.
    • 



Use this request body:


{
    "environmentKey": "environment-key-123abc",
    "instructions": [{
        "kind": "addClauses",
        "ruleId": "a902ef4a-2faf-4eaf-88e1-ecc356708a29",
        "clauses": [{
            "contextKind": "user",
            "attribute": "country",
            "op": "in",
            "negate": false,
            "values": ["USA", "Canada"]
        }]
    }]
}



addPrerequisite


Adds the flag indicated by key with variation variationId as a prerequisite to the flag in the path parameter.


Parameters


    

  • key: Flag key of the prerequisite flag.
    • 

  • variationId: ID of a variation of the prerequisite flag.
    • 



Use this request body:


{
    "environmentKey": "environment-key-123abc",
    "instructions": [{
        "kind": "addPrerequisite",
        "key": "example-prereq-flag-key",
        "variationId": "2f43f67c-3e4e-4945-a18a-26559378ca00"
    }]
}



addRule


Adds a new targeting rule to the flag. The rule may contain clauses and serve the variation that variationId indicates, or serve a percentage rollout that rolloutWeights, rolloutBucketBy, and rolloutContextKind indicate.

Click to expand instructions for updating the flag lifecycle


These instructions do not require the environmentKey parameter. They make changes that apply to the flag across all environments.


archiveFlag


Archives the feature flag. This retires it from LaunchDarkly without deleting it. You cannot archive a flag that is a prerequisite of other flags.


{
  "instructions": [ { "kind": "archiveFlag" } ]
}



deleteFlag


Deletes the feature flag and its rules. You cannot restore a deleted flag. If this flag is requested again, the flag value defined in code will be returned for all contexts.


Use this request body:


{
  "instructions": [ { "kind": "deleteFlag" } ]
}



restoreFlag


Restores the feature flag if it was previously archived.


Use this request body:


{
  "instructions": [ { "kind": "restoreFlag" } ]
}






Using JSON Patches on a feature flag


If you do not include the header described above, you can use JSON patch.


When using the update feature flag endpoint to add individual targets to a specific variation, there are two different patch documents, depending on whether there are already individual targets for the variation.


If a flag variation already has individual targets, the path for the JSON Patch operation is:


{
  "op": "add",
  "path": "/environments/devint/targets/0/values/-",
  "value": "TestClient10"
}



If a flag variation does not already have individual targets, the path for the JSON Patch operation is:


[
  {
    "op": "add",
    "path": "/environments/devint/targets/-",
    "value": { "variation": 0, "values": ["TestClient10"] }
  }
]



Required approvals


If a request attempts to alter a flag configuration in an environment where approvals are required for the flag, the request will fail with a 405. Changes to the flag configuration in that environment will require creating an approval request or a workflow.


Conflicts


If a flag configuration change made through this endpoint would cause a pending scheduled change or approval request to fail, this endpoint will return a 400. You can ignore this check by adding an ignoreConflicts query parameter set to true.

Copy feature flag


Copying flag settings is an Enterprise feature


Copying flag settings is available to customers on an Enterprise plan. To learn more, read about our pricing. To upgrade your plan, contact Sales.




Copy flag settings from a source environment to a target environment.


By default, this operation copies the entire flag configuration. You can use the includedActions or excludedActions to specify that only part of the flag configuration is copied.


If you provide the optional currentVersion of a flag, this operation tests to ensure that the current flag version in the environment matches the version you've specified. The operation rejects attempts to copy flag settings if the environment's current version  of the flag does not match the version you've specified. You can use this to enforce optimistic locking on copy attempts.


Request 
path Parameters
projectKey
required
string <string> 
The project key


 
featureFlagKey
required
string <string> 
The feature flag key. The key identifies the flag in your code.
