When requesting, pass in the value you configured in AUTHORIZATION to poll multiple accounts. AUTHORIZATION can be configured with multiple values separated by commas.

Environment variables

Each environment variable has a default value. If you do not understand the meaning of the environment variable, please do not set it, let alone pass an empty value.
