lib.callback / lib.callback.await

Summary

Type-safe client↔server callbacks via ox_lib. Cleaner than manual event round-trips for request/response patterns.

Returns

any — the value returned by the other side.

Example

-- CLIENT asks SERVER
local result = lib.callback.await('myscript:getBalance', false)

-- SERVER registers
lib.callback.register('myscript:getBalance', function(source)
  local Player = QBCore.Functions.GetPlayer(source)
  return Player and Player.PlayerData.money.bank or 0
end)

Common pitfalls

• await yields — use inside a thread.
• Still validate the source server-side; callbacks aren't a security boundary.
• Requires ox_lib.
