Simply go to your Component.js file and add this line to the init function:
this.getModel().setHeaders({"myCustomParameter": "test"})
In a CAP Backend, you get this parameter from the express req object, which can be accessed via the req.http property:
req.http.req.headers['myCustomParameter']
And here is a nice code snippet, on how to read this header parameter in an ABAP system: https://answers.sap.com/answers/425621/view.html

All options have in common that you first try to get the binding context from the list/table element via the event. Having the right context, you can either use the getProperty() function to get a specific property, or use the getObject() function to get all data.
onClick: function (oEvent) {
// Option 1
oEvent.getParameters().item.getBindingContext().getProperty("ID") // when having a list
// Option 2
oEvent.getParameters().item.getBindingContext().getObject().ID
// Option 3
oEvent.getParameter("item").getBindingContext().getObject().ID
// Option 4
oEvent.getSource().getBindingContext().getObject().ID
}
Note: When using a List, it’s oEvent.getParameters().listItem instead of oEvent.getParameters().item.
Or you could also use the sPath property from the binding context and directly get the data from the model.
onClick: function (oEvent) {
// Option 5
const sPath = oEvent.getSource().getBindingContext().sPath
// 5a
this.getView().getModel().getProperty(sPath).ID
// 5b
this.getView().getModel().getProperty(sPath + "/ID")
}

There are two ways to use a filter.
Option 1:
items="{
path: '/myItems',
parameters : {
$filter : 'itemName eq \'myItemName\'',
$orderby : 'createdAt desc'
},
}">
Option 2:
items="{
path: '/myItems',
parameters : {
$orderby : 'createdAt desc'
},
filters : {
path : 'itemName ',
operator : 'EQ',
value1 : 'myItemName'
},
}">
