Mashup Integration and communication with an external System

Dear Community,

I want to call a self created Mashup which accepts one or more parameters (like google maps)

I created a BO for creating WoC + WoC-View and linked that Mashup to the WoC-View.

Now I want to call the mashup with parameters. How can I send the parameters, which will be stored in a bo
extension for the bo employee, to the mashup?

Best regards,

Jamil
