Issue symptoms
I tried to use a cURL command through the terminal as explained in the documentation, Test your cURL installation. However, I received this error message:
curl: (3) URL using bad/illegal format or missing URL
Resolution
Special characters in your password cause the error curl: (3) URL using bad/illegal format or missing URL. Characters such as @, &, or other symbols cause problems on the command line.
To fix this issue, add double quotes around your URL:
"username@domain.net"
If that doesn't fix the issue, generate a new API token instead of a password.
