How do I add the option for setting a custom header in a curl config file? Neither of the following lines did work:
Header = \'x-abc: xyz\' header = \'x-abc:
Regarding your snippet with the code: you just needed to use double quotes " instead of single quotes '.
"
'
With this change both statements work fine.
Header = "x-abc: xyz" header = "x-abcd: xyz"
