    Hi @ayrton01cz,

    This might help you: https://developers.google.com/admin-sdk/reports/v1/guides/delegation#delegate_domain-wide_authority_to_your_service_account with a https://www.googleapis.com/auth/gmail.send scope.

    Please try and reply back with the results.

    Hello Slava,

    I have the exact same error-code (400). Surprisingly the error is not identical with the error given on:
    https://wpforms.com/how-to-securely-send-wordpress-emails-using-gmail-smtp/
    I am not sure if authentication is missing.

    Versions:
WordPress: 4.9.4
WordPress MS: No
PHP: 7.2.2
WP Mail SMTP: 1.2.5

Params:
Mailer: gmail
Constants: No
Client ID/Secret: Yes
Auth Code: Yes
Access Token: Yes

Server:
OpenSSL: Yes
PHP.allow_url_fopen: No
PHP.stream_socket_client(): Yes
PHP.fsockopen(): Yes
PHP.curl_version(): Yes

Debug:
Error while sending via Gmail mailer: {
"error": {
"errors": [
{
"domain": "global",
"reason": "failedPrecondition",
"message": "Bad Request"
}
],
"code": 400,
"message": "Bad Request"
}
}

    Plugin and configuration has been done by simply following the instructions from my link above. No other SMTP or caching plugin is installed. Everything is up-to-date. Somehow I am assuming it might have sth to do with security restrictions I added. See error code line: PHP.allow_url_fopen: No
    I tried to follow the instructions you’ve given above, but I have no g suite account. Because I wasn’t sure where to put the https://www.googleapis.com/auth/gmail.send I tried it in my Gmail API (see scrrenshot: https://ibb.co/b8O5h7). You will find this part in the credentials tab -> restrictions.
    I will go through my .htaccess and functions.php to look for security restrictions I set. Hope to find the error and will report back, maybe someone else is having same issue.
    If you have other ideas leading to the goal, they are highly appreciated. 🙂

    Best regards,

    -Björn

    Edit:
    Neither it was the implemented 6g firewall or xss-header configuration, nor the PHP.allow_url_fopen setting. This is set to ‘Yes’ now, but with same result.
