Google chrome extension Simple REST Client
This link suggested adding
"Content-Type: application/x-www-form-urlencoded" in the header box and a paramlist:
(param1=val1¶m2=val2&...) in the data box, which worked for me.
For "Headers", each header needs to be on a newline:
Content-Type: application/jsonUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.84 Safari/537.36While "Data" needs to be in json-format, so something like this:
{"login":"USERNAME","password":"PASSWORD"}using a paramlist did not work for me.
