Connect Codex to Expensify

Give an AI agent your Expensify account as a tool and it can actually move expenses through the pipeline instead of just talking about them. It can create expenses, build reports, mark them reimbursed, run a reconciliation export, and update policies or expense rules on its own, calling each operation as it works. Wire it into a coding agent in NoClick and it can close out an expense cycle or fix a misconfigured policy without a person clicking through the Expensify UI.

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
