Hi, I have a task to connect to a HTTP client which is a post service, which has content-type is application/x-www-form-urlencoded and in body I have to send userid, password. I am setting these userid, password in request header but still these parameters are going empty. Even I gave these parameters as "replacement variable" and setting in parameters tab still parameters are not going in the request. I have search in google for the same it has given a solution to use dynamic document property still it is not working. Can you please help me in this scenario or provide any useful links to refer. Do I need to use profile also?
