GetUserRank
public BackendReturnObject GetUserRank(string rankUuid, string userInDate);
public BackendReturnObject GetUserRank(string rankUuid, string userInDate, int gap);
The URank ranking method can only look up NULL groups in grouped leaderboards.
If you want to check leaderboards according to groups, use the Leaderboard method. 
Parameters
| Value | Type | Description | Default | 
|---|---|---|---|
| rankUuid | string | uuid of the ranking to look up | - | 
| userIndate | string | inDate of the user to look up | - | 
| gap | int | Number of rank holders above/below to be looked up together (0 - 25) | 0 | 
The rankUuid value can be checked using the following methods:
- Create a ranking in BACKND Console and check the uuid value from the information of the ranking
 - Check the uuid value using the Look up ranking information of all users method
 
The userIndate value can be checked using the following methods:
- Check the inDate of your friend
 - Check the inDate of a guild member
 - Check using the owner_inDate column of the public table
 - Check by sharing the inDate of a user
 
Description
Looks up the user's rank in the ranking using a uuid value and userIndate.
- If there is a tie between users (with the same rank), users with the same ranks may be returned when the gap method is used for the lookup.
 
Example
Synchronous
// Look up the ranking of the user only
Backend.URank.User.GetUserRank("rankUuid", "userIndate");
// Look up the ranking including three users above and below
// If the user is the 4th, the 1st - 7th users are looked up.
Backend.URank.User.GetUserRank("rankUuid", "userIndate", 3);
Asynchronous
// Look up the ranking of the user only
Backend.URank.User.GetUserRank("rankUuid", "userIndate", callback => {
    // Post-process
});
// Look up the ranking including three users above and below
// If the user is the 4th, the 1st - 9th users are looked up
Backend.URank.User.GetUserRank("rankUuid", "userIndate", 5, callback => {
    // Post-process
});
SendQueue
// Look up the ranking of the user only
SendQueue.Enqueue(Backend.URank.User.GetUserRank, "rankUuid", "userIndate", callback => {
    // Post-process
});
// Look up the ranking including three users above and below
// If there are 10 users in the ranking and the user is the 9th,
// the 6th - 10th users are looked up
SendQueue.Enqueue(Backend.URank.User.GetUserRank, "rankUuid", "userIndate", 3, callback => {
    // Post-process
});
