Hi everyone, with the announcement of League Classic we want to share a quick but important update regarding its data. League Classic match history data will not be available via the Riot API and to preserve the spirit of the mode, we ask that League Classic data not be aggregated or displayed to users in any form. However, League Classic will be supported as a valid map type in our Tournament API allowing for the creation and management of community-led League Classic tournaments.

Hey everyone, we wanted to let you know that we are deprecating leagueId within the Riot API. Since leagueId is going away, we will be retiring the endpoint /lol/league/v4/leagues/{leagueId} and recommend using the following endpoints instead: /lol/league/v4/challengerleagues/by-queue/{queue} /lol/league/v4/entries/{queue}/{tier}/{division} /lol/league/v4/grandmasterleagues/by-queue/{queue} /lol/league/v4/masterleagues/by-queue/{queue}

Hi all, we wanted to let you know that a recent issue with our Match-V5 API not respecting startTime and endTime query parameters has been fixed. Thanks to everyone who reported this issue and for bearing with us while we worked to resolve it!

Hi all, alongside LoL patch 25.17 we are adjusting our developer policies. There are a few specific use cases for LoL apps that will no longer be approved like notifying players of a power spike(e.g. Garen just leveled up to 6), dictating player actions, and tracking enemy ability/summoner spell cooldowns. You can out our full list of policies at developer.riotgames.com/poli….

Hey everybody, as a follow up to our last announcement about the endpoints being removed, we are going to be completely removing SummonerIDs and AccountIDs from all endpoint payloads on July 7th, 2025. If your app is dependent on them, please take steps to ensure that you can use PUUIDs moving forward. Also, please make sure to use this endpoint for RSO-related summoner requests: /lol/summoner/v4/summoners/me

Hi all, we are removing many endpoints from the Riot API associated with AcountIDs and SummonerIDs on June 20th. Moving forward, please use the PUUID equivalents of these endpoints which are already available! Endpoints being removed: /lol/league/v4/entries/by-summoner/{encryptedSummonerId} /lol/summoner/v4/summoners/by-account/{encryptedAccountId} /tft/league/v1/entries/by-summoner/{summonerId} /tft/summoner/v1/summoners/by-account/{encryptedAccountId} /tft/summoner/v1/summoners/{encryptedSummonerId} /lol/summoner/v4/summoners/{encryptedSummonerId}

Hey everyone, we’ve updated our policy around advertising in Riot games. Third party in-game advertisements are no longer allowed, this includes ads in overlays, during loading screens, and in the Riot Client. If you’re interested in our full list of policies, check out the documentation on our website for more info: developer.riotgames.com/poli…

Hi all, match history data for the new Brawl game mode will not be available through Riot's API when it releases. With Brawl being experimental, we are not in a place where this type of game mode can be supported and we believe that winrate-based data would be detrimental to the Brawl player experience for its duration. As a result of this, querying the Riot API for Brawl match data will result in a 403 error.

Hi everyone, we are aware of an ongoing issue with Swiftplay matches not being available through MATCH-V5 and are working to fix this. Until this problem is resolved, Swiftplay matches can still be accessed via the LOL-RSO-MATCH-V1 API, which uses RSO authentication.

Hi all, we will be removing the by summoner ID endpoint from clash-V1 with the release of the next LoL patch and replacing it with a by puuid endpoint. Everyone should plan to transition off the summoner ID endpoint prior to us deprecating it. Old endpoint: developer.riotgames.com/apis… New endpoint: developer.riotgames.com/apis…

Hey folks, the RSO issues should now be resolved. If you continue experiencing trouble with this, please let us know on our support site: support-developer.riotgames.…

Hi all, we're aware of the RSO issues some third parties are experiencing. We're working to fix this as quickly as we can and will let you know when it has been resolved.

Hi all! We’re excited to share that you can now access custom lobby match history using League of Legends enabled RSO clients. To protect player privacy, you can only get custom match history using RSO clients, NOT your product API key. Additionally, this comes with a new policy: Third party sites may not publicly display a player's match history from the custom match queue unless the player opts in to share this specifically for League of Legends. Otherwise, a player’s custom match data may only be made available to them using RSO. If you have any questions about this, feel free to send us a message on our support site: support-developer.riotgames.…
