Your goal	Recommended path	Installation
Use Codex App, Codex CLI, or Claude Code	Create a key and import it into CC Switch	CC Switch and the target client
Generate product images	Creative Studio	None

Path 1: use Codex or Claude Code

This path needs an API key from the correct plan group. CC Switch imports and switches provider settings, but it does not install the target client.

Prepare the target client

For Codex CLI or Claude Code, install the LTS version of Node.js from nodejs.org. Skip Node.js if Codex App is already installed.

Codex CLI: npm install -g @openai/codex
Claude Code: npm install -g @anthropic-ai/claude-code

Install only the client you plan to use. An installed Codex App does not require a second CLI installation.

Create a key from the correct plan group

Open Key Management and create a key. Use a Claude-group key for Claude Code and a Codex / GPT-group key for Codex. Never paste a complete key into chat, a support ticket, or a screenshot.

Import into CC Switch and enable

Open the key row's More menu and select Import CCS. Choose Codex CLI for Codex App or Codex CLI; choose Claude Code for Claude Code. Confirm the import when the browser opens CC Switch, select the matching client tab, and choose Enable. Follow the screenshot guide for every click. Restart Codex App or open a new CLI terminal after switching.

Path 2: create product images

Sign in to the console, then open Creative Studio. Choose Image, enter a prompt, and set the model, aspect ratio, or size. This path does not require an API key.
