How to send POST data?

[q2apro]

Simple question, but could not figure it out. Missing in the description - and could not find a documentation.

1. Clicking on POST
2. Data textfields opens
3. I tried to enter mail=test@github.com
4. My script checked, could not get the POST data $_POST['mail']

Can you please help.

I have set the header to Content-Type: application/x-www-form-urlencoded -seems to work now. https://stackoverflow.com/q/14551194/1066234

Can you add Content-Type: application/x-www-form-urlencoded as default insert into the Headers field? This would help a lot and save a lot of time.
