We announced in October 2018 that developers could begin to create tools using the LCU API (https://www.riotgames.com/en/DevRel/league-client-apis-policy-update). After reviewing some of the applications that have been released and talking to our regional offices we will be making some changes.
- For the time being we will no longer allow players in Korea to use applications leveraging the League Client API.
- Before you release an application (or an update to your existing application) that uses the League Client API in any region, you must contact us and let us know.
- Only endpoints on our approved list are allowed for use by developers
We have also updated our policies to better reflect these changes https://developer.riotgames.com/league-client-apis.html
