Requirement to pull the result in a process model

Hi,

We have created interface with grid pulling the result of webservice result Webservice Name and Status "Active" , "Failed".

Now we have requirement to pull the result in a process model and need to call this interface in script task with an expression rule and send an email to the group. Could anyone let me know how to pull this record from the interface.

Interface:
load(
local!studyWebserviceUp: if(rule!RSU_WS_getStudyDetailsByUserIdInput(userId: loggedInUser()).httpStatusCode=200, "Active","Failed"),

a!dashboardLayout(
contents: {

a!sectionLayout(
label: "RSU Webservices",
contents: {
a!columnsLayout(
columns: {
a!columnLayout(
contents: {

a!dateField(
label: "Today Date",
labelPosition: "ADJACENT",
value: today(),
readOnly: true
)
}
)
}
)
}
),
a!sectionLayout(
label: "Items",
contents: {
/* This grid is not configured to page or sort */
a!gridField(
labelPosition: "ABOVE",
totalCount: 3,
columns: {
a!gridTextColumn(label: "Webservices", data: {"Study Webservice", "TMDH Werbservice", "Site Webserivce"}),
a!gridTextColumn(label: "Status", data: {local!studyWebserviceUp, local!studyWebserviceUp, local!studyWebserviceUp}),
/*a!gridTextColumn(label: "Qty", data: {2, 1, 2}, alignment: "RIGHT"),*/
/*a!gridTextColumn(label: "Unit Price", data: {dollar({150, 50.99, 30.99}), "Total"}, alignment: "RIGHT"),*/
/*a!gridTextColumn(label: "Amount", data: dollar({300, 50.99, 61.98, 412.97}), alignment: "RIGHT")*/
},
value: a!pagingInfo(startIndex: 1, batchSize: 5),
saveInto: {}
)
}
)
}
))
