question

The Id of the Entity returned from GetMatch is the title_player_account id, and I am assuming that you want to retrieve the opponent’s profile using GetPlayerProfile, which uses the PlayFabId ( the same as the master_player_account id), is that correct?

If that’s your case, so the question now is how to get the PlayFab Id (master_player_account id) from the title_player_account id. The GetProfile API can retrieve it, it’s returned in GetEntityProfileResponse -> Profile -> Lineage -> MasterPlayerAccountId, so that you can use it with GetPlayerProfile to retrieve the opponent’s profile data. However, one thing to note is, by default, a player entity cannot use GetProfile to retrieve other player’s entity profile, you have two options:

1. Use the server side logic to retrieve & return the PlayFabId back to the client side, for instance, using CloudScript. And, you can even retrieve & return the opponent’s profile as well, leaving all the job to server side.
2. Add the following policy statement into the ENTITY GLOBAL TITLE POLICY ( Under GameManager -> Settings -> API Features), or do it with SetGlobalPolicy:

{
    "Action": "Read",
    "Effect": "Allow",
    "Resource": "pfrn:data--*!*/Profile/*",
    "Principal": "*",
    "Comment": "allow title player access other's profiles ",
    "Condition": {
      "CallingEntityType": "title_player_account"
    }
  }

So that you can retrieve the opponent’s PlayFab Id directly from the client side, and proceed with GetPlayerProfile.
