Fivem Latent Callbacks

This script delivers a secure client-server callback system for FiveM that supports both standard and latent events, enabling safe handling of large payloads with bandwidth throttling.

Built-in protections include promise-based requests, duplicate ticket prevention, owner verification, strict event validation, and configurable rate limiting to block abuse. Use RegisterSecureCallback with validators for sensitive operations such as purchases or data checks.

• Promise-based sync or async callbacks
• Latent mode for capped large data transfers
• Duplicate protection and owner verification
• Rate limiting, payload caps, and concurrency controls
• Secure registration helper with validator support
