Connect Codex to WhatsApp

Give a coding agent your WhatsApp Business account as a tool and it handles your messaging on its own. It can list recent chats and read chat messages, edit a sent message, create and manage message templates, download media and resolve a media URL, and pull account, profile, and phone number info, calling each as a tool while it works. Connect it to a hosted agent in NoClick and it reads a thread, then edits or templates a reply without a step-by-step from you.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing
Good at well-scoped, concrete tasks
Strong at API and data manipulation
Familiar to teams already on OpenAI tooling
