create a web service with body as JSON

[Anonymous]

Can I create a web service (post) with body as JSON?

I found these subject in Talend help administration

https://help.talend.com/reader/NCvLSgL85zqYq7YwX3T3jQ/zUxfgmX9DviKbaPjk5xreA

but the request as Soap message, and I saw I can change the protocol in port to http but I do not understand that.

Thanks.
