Hi!
An y example, how can i attach a file?

Did you found how to add a CSV attachment?

Hi!

No, nothing. I solved this problem with python because i didn't find any solution with bash.

Hey,
In bash, we have to convert the file into base64 encoded format and store in a variable and then pass that variable in the attachment key, so that it accepts the file and sends out an email with attachment

What about files?

?

This doesn't work:

{"errors":[{"message":"Bad Request","field":null,"help":null}]}

@TitanRob16 Had the same issue. For me, I had to remove the single quote in the line --data "'$maildata'". I am on bash 5.0.x, btw.

Hey guys. How we can put value from bash variable as a body letter template. Can somebody help with it

Something like this :
bodyHTML=echo -e "$LETTER"

....

maildata='{"personalizations": [{"to": [{"email": "'${EMAIL_TO}'"}]}],"from": {"email": "'${FROM_EMAIL}'",
"name": "'${FROM_NAME}'"},"subject": "'${SUBJECT}'","content": [{"type": "text/html", "value": "'${bodyHTML}'"}]}'

yuck.
