Working Behind a Proxy

How a Proxy Server is Chosen?

PTB will obtain its proxy configuration in the following order (the first to be found will be used):

1. Programmatic.
2. Using HTTPS_PROXY environment variable.
3. Using https_proxy environment variable.

REQUEST_KWARGS={
    'proxy_url': 'URL_OF_THE_PROXY_SERVER',
    # Optional, if you need authentication:
    urllib3_proxy_kwargs = {
        'username': 'PROXY_USER',
        'password': 'PROXY_PASS',
    }
}

updater = Updater(TOKEN, request_kwargs=REQUEST_KWARGS)
