Codex CLI

Configuration

To disable telemetry:

analytics = { enabled = false }
feedback = { enabled = false }

requires_openai_auth = true

If using a single provider with responses API, you may set requires_openai_auth on the model provider and save your API key with codex login:

printenv OPENAI_API_KEY | codex login --with-api-key
codex login --with-api-key < my_key.txt

Otherwise, use API key (if needed) from the “env_key” environment variable, or specify the header statically:

http_headers = { "Authorization" = "Bearer sk-..." }
