Goal

This guide explains how to manage the lifecycle of a feature flag using the Automation API. Configure the first flag by completing the following steps:
  1. Create a feature flag using the create a new feature flag endpoint.
  2. Add a rollout rule to the development environment using the update a feature flag configuration endpoint.
  3. Update the rollout rule using the update a single rule by ID endpoint.

​
Requirements

​
Prerequisites

Before using the Automation API, ensure the following information is available:

​
Access token

The Automation API requires an access token. Obtain a token by following the instructions in Obtaining an access token.

​
siteCode

Find the siteCode by navigating to Admin > Projects in the bottom-left corner.
SiteID

​
1. Create a feature flag

Create a feature flag called test_feature_flag_post, for example, with the variable test_variable. Because this request does not specify environmentConfigurations, the system automatically generates configurations for the development, staging, and production environments. Endpoint: 
POST https://api.kameleoon.com/feature-flags
See the Create a new feature flag endpoint. Example: 
curl -L -X POST 'https://api.kameleoon.com/feature-flags' \
-H 'Content-Type: application/json' \
-H 'Accept: */*' \
-H 'Authorization: Bearer <ACCESS_TOKEN>' \

2. Update the feature flag

Update the feature flag to add a TARGETED_DELIVERY rollout rule to the development environment with the following configuration:
Endpoint: 
PATCH https://api.kameleoon.com/feature-flags/:siteCode/:featureKey
