Set/send email with bcc via rest send api?


we send emails with the rest api using the following endpoint:


How can an email send with this endpoint send also via bcc to another email address?

I tried to set bcc in the email directly in mautic and also into the json body of the response:

'json' => [
    'tokens' => $tokens,
    'bcc' => '',

But both ways are not working. I also found some other topics/issues with that but I’m not sure if there is a bug/problem with that or if I just doing something wrong.

Thanks for some help!

Best regards,
