Feature Flag Setup¶

A Feature Flag is a statement in your code that specifies how the app should behave when the flag is “on” or “off”. This logic can be used multiple times in your code.

Android (Java)¶

if (Apptimize.isFeatureFlagOn("new_feature_flag_variable")) {
   // ON
} else {
   // OFF
}

Android (Kotlin)¶

val userId = "1234abcd";
if (Apptimize.isFeatureFlagEnabled("new_feature_flag_variable", userId)) {
  // ON
} else {
  // OFF
}

iOS (Objective-C)¶

if ([Apptimize isFeatureFlagOn:@"new_feature_flag_variable"]) {
   // ON
} else {
   // OFF
}

iOS (Swift)¶

if (Apptimize.isFeatureFlag(on: "new_feature_flag_variable")) {
   // ON
} else {
   // OFF
}

JavaScript¶

if (Apptimize.isFeatureFlagEnabled("new_feature_flag_variable")) {
   // ON
} else {
   // OFF
}

Node.js¶

var userId = "1234abcd";
if (Apptimize.isFeatureFlagEnabled("new_feature_flag_variable", userId)) {
   // ON
} else {
   // OFF
}

Python 3¶

userId = "1234abcd"
if Apptimize.isFeatureFlagEnabled("new_feature_flag_variable", userId):
   # ON
else:
   # OFF

Rest API¶

curl -X GET \
-H "ApptimizeApiToken: <ApiToken>" \
https://api.apptimize.com/v1/users/1234abcd/feature-flags/new_feature_flag_variable

Roku¶

userId = "1234abcd"
m.requestId = m.apptimize.callFunc("isFeatureFlagEnabled", {userid: userId, name: "new_feature_flag_variable", customAttributes: {}})

' Requires setup of setcontent callback as described in Roku installation steps
function setcontent(message as object)
apptimizeResponse = message.getData()
if (apptimizeResponse.id = m.requestId) then
  ?"Feature Flag: ";apptimizeResponse.response.isFeatureFlagEnabled
end if
end function

The variable name used (new_feature_flag_variable in the example above) should match the variable name within the “Create Code” tab of your feature flag. This links the Feature Flag in the Apptimize dashboard to your app’s code. We recommend using the “Create Code” option to generate the snippet you will use to avoid errors.
