How to post data through REST API's ? client.http service only ..

it depends on End Provider, Please check with How they are Expecting input as key value pair or simple value ...

I think u can invoke REST ful Service using Soap UI 4.6.1 Invoke it, then u can implement very easily...

But client unable to access SOAP message ...they want to expose though HTTP POST . But we dont have HTTP port available

Thanks Tomasidn, for sharing your knowledge

Input might be json string
Or key value pair like input= json string
Check with them or else sometimes u need to pass the request along with the URL
