User ID

A user's User ID (also written userid) is an immutable ID linked to their user account.

Format

All user IDs will start with the string U- (the letter "U" signifying "user" while other letters like "G" or "R" will mean "group" and "record" for the most common).

There are currently two user IDs formats.

Regular user ID

Most Resonite user IDs will be a Snowflake ID, following the format U-<snowflake>.

For instance, a regular user ID might look like U-fX3pKe7AYYQ.

Username user ID

In the case of migrated accounts or system accounts such as the Resonite bot, the user ID string can appear in a different format.

In such cases, it will follow the format U-<username>.

For instance, a username user ID might look like U-Frooxius.

Never ever assume a user ID will match a username.

Use

It is generally recommended to not display this ID in user-facing scenarios (facets, worlds, ect) and instead display the username of the user by using the UserUsername ProtoFlux node.

As the user ID is immutable, it can be recommended to use it for cloud variables and components such as ValueUserOverride.

Finding a user ID

Finding user IDs can be simple and done in multiple ways:

• Logging onto the Resonite account website will display your own user ID
• Using the UserFromUsername ProtoFlux node in combination with a UserUserID node (this will only work in sessions where the user is present)
• Using a user inspector (this will also only work for users present in the session)
• Use the API to search and find users
• Use a tool such as marsmaantje's user searcher (resrec:///U-marsmaantje/R-c671fca0-7b46-413f-a116-d57b8fbdbeba)
