How to fetch feature flag definitions without using the admin API key

Question

When using Admin API, it's possible to fetch the feature flag definitions. Is it possible to fetch feature flag definitions definitions for one Environment only using the SDK API key?

Answer

It is possible to use the SDK HTTP call to fetch all the feature flags definitions that are added to the Environment's SDK API key.

Important Note: This call is not published, therefore the structure might change without notice.

The curl below will fetch all feature flags' information in a JSON structure. The payload is gzipped:

curl -H "Authorization: Bearer [SDK APIKey]" -H "Accept-Encoding: gzip, deflate, br" -H "Accept: application/json" https://sdk.split.io/api/splitChanges?since=-1 | gunzip
