how to create webservice in IFS 9

Hi @m.arif,

BizAPIs can be developed as customizations for Middle Tier Integration development using IFS Connect.

However, there are some out of the box webservices developed by IFS and are bundled with your application.
You can browse them using the IFS Interface Browser.

Do we need to have a developer license for doing that?

Please contact your local IFS representative regarding this.
