I’m saving base64 encoded html in a custom field via the API. I’m looking to add the custom field to a email template and it decode the Base64 when sending emails.
This extension https://github.com/mtcextendee/mautic-custom-tags-bundle seems to be what i’m looking for, but the author said he will not be upgrading it to M3.
I have this working when sending emails via a API by adding a prefix to the base64 string…
$value = base64_decode(substr($value, 9));
But cant seem to find where to hack the code for sending email via a template.
Any help is appreciated!
