    I just completed the setup for GMail and added the Client ID and Secret. No extra spaces anywhere. I checked. Receiving 401 errors for invalid_client like this inside of WP SMTP:

    Email Source: WooCommerce
    Mailer: Google / Gmail
    {
    "error": {
    "code": 401,
    "message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
    "errors": [
    {
    "message": "Login Required.",
    "domain": "global",
    "reason": "required",
    "location": "Authorization",
    "locationType": "header"
    }
    ],
    "status": "UNAUTHENTICATED",
    "details": [
    {
    "@type": "type.googleapis.com/google.rpc.ErrorInfo",
    "reason": "CREDENTIALS_MISSING",
    "domain": "googleapis.com",
    "metadata": {
    "method": "caribou.api.proto.MailboxService.SendMessage",
    "service": "gmail.googleapis.com"
    }
    }
    ]
    }
    }

    And in Google itself I get this:

    Error 401: invalid _client
    Request details: flowName=GeneralOAuthFlow

    The page I need help with: [log in to see the link]
