# CLI reference > Every epx command and flag, with the OAuth scopes each one requests. This reference documents every command and flag of epx. The same text is in `epx --help`. Command-line client for the Emporix Commerce APIs. Credentials are read from the environment: ```text EMPORIX_TENANT, EMPORIX_CLIENT_ID, EMPORIX_CLIENT_SECRET (and optionally EMPORIX_API_URL). ``` Where none of these is set, a profile ([`epx profile add`](https://commerce-cloud-integrations.github.io/emporix-cli/commands/profile#epx-profile-add)) gives them, its client secret from the OS keychain: the profile that `--profile` names, else EPX_PROFILE, else the default profile ([`epx profile use`](https://commerce-cloud-integrations.github.io/emporix-cli/commands/profile#epx-profile-use)). The two never mix, and naming a profile while one is set is a usage error. `--tenant` overrides the tenant of either. A profile's default site and language apply where a command needs a site or shows translations and the flag is not given, on the profile's tenant. Exit codes: 0 success, 1 error, 2 invalid usage or configuration, 3 authentication or missing scopes, 4 not found, 5 conflict: a write that Emporix answered with 409 Conflict, as when the item changed since it was read or exists already, or a `units update` or `catalogs patch` with metadata.version answered with 404 Not Found, as the Unit and Catalog services answer a stale version. A 403 Forbidden that the help of a command calls a refusal of its input exits 1. ## Global flags Every command takes these flags. - `-h, --help`\ Help for epx. - `--profile `\ Profile to use (default from EPX_PROFILE, else the default profile). - `--tenant `\ Emporix tenant (default from EMPORIX_TENANT, else the profile). - `--timeout `\ Timeout for each HTTP request.
