`QBCore.Functions.CreateCallback`

QBCore server documentation with a FiveM Lua example.

Summary

Registers a server callback the client can call and await a response from — the clean request/response pattern in QBCore.

Returns

void

Parameters

namestringThe callback name.

handlerfunctionfunction(source, cb, ...) — call cb(result) to respond.

Example

-- SERVER
QBCore.Functions.CreateCallback('myscript:getBalance', function(source, cb)
  local Player = QBCore.Functions.GetPlayer(source)
  cb(Player.PlayerData.money.bank)
end)

-- CLIENT
QBCore.Functions.TriggerCallback('myscript:getBalance', function(bank)
  print('Bank: ' .. bank)
end)

Common pitfalls

Always call cb() exactly once, or the client waits forever.
Validate the source server-side — callbacks are still a network boundary.
