Additional Context (if applicable)

Hello, i have an issue, I am just trying to obtain an eg1 token at the https://account-public-service-prod.ol.epicgames.com/account/api/oauth/token URL I have included the grant_type param as authorization_code and the code param as the one I obtain from https://www.epicgames.com/id/api/redirect?responseType=code&clientId=ec684b8c687f479fadea3cb2ad83f5c6 (logged in) (fortnitePCGameClient id)

However, I keep getting a "Malformed grant type in token request" on the response

I don't know if i am missing any steps I also tried the token_type eg1 param (described in the docs) with no success (same error)

Is there something wrong I am doing? Also, I believe the eg1 token is needed to access https://events-public-service-live.ol.epicgames.com/ which is what I am trying to do, if it isnt or there is any other recommended way to get this token could you tell me? Like alternate grant types (I couldnt get device auth working too, the required Auth isnt really described well in here, as i got this errors.com.epicgames.common.authentication.authentication_failed error)

Hi,

1. yes the authorization code is sensitive
2. you are supplying the "grant_type" and "code" as a query parameter (in the url) but they need to be in the "Body" as ``. Check out the example requests how to auth here. In postman it's done like this:
3. regarding eg1 tokens, i would recommend to always use them, you can easily get info about the session without sending a request (to the verify api) and certain apis require you to supply an eg1 token

hope this helps

Yeah, I seem to have fixed the issue Could you help me with something else? https://events-public-service-live.ol.epicgames.com/api/v2/games/FNFestival/leaderboards/season003_54a2b46e-7fc7-4ec9-869f-e011fd8b41a6/54a2b46e-7fc7-4ec9-869f-e011fd8b41a6_Solo_Vocals/scores?accountId=3554e7171c554bdc8b38edb226fe6b0f&fromIndex=0&findTeams=false I try accessing this

Using the eg1 token (Bearer eg1) i got, this response { "errorCode": "com.epicgames.api.malformed_data", "errorMessage": "com.fasterxml.jackson.databind.exc.MismatchedInputException: No content to map due to end-of-input\n at [Source: (byte[])\"\"; line: 1, column: 0]" }

I dont recognize this kind of error

[LeleDerGrasshalmi]

you disabled the content length header, so the api doesnt know anything about a body/payload, so it fails to parse it.

[tposejank]

Yeah, seem to have got it right after countless attempts! Thanks Lele!

[tposejank]

By the way, I can't seem to find docs about the festival leaderboards, would you like if I made some?

[LeleDerGrasshalmi]

np and you dont need to add them, i will eventually add them
