Mapping request body fields in logic apps - json

Question

We have configured common alert schema for alerts and we are using a ticketing software and whenever we receive alert it should create a ticket.
In the logic app I have to make Post API call for creation of ticket with following json object, some fields are hard coded values:
{
"subject": "",
"Id": "123456789", // Hard code value
"priority": "",
"email": "test#test.com", // Hard code value
"status": "Open" // Hard code value
}
Parse Json sample payload schema for Alert:
{
"data": {
"alertContext": {
},
},
"customProperties": null,
"essentials": {
"alertContextVersion": "123",
"alertId": "123",
"alertRule": "Test Alerts",
"description": "test",
"severity": "Sev4"
}
},
"schemaId": "test"
}
I have to map "subject and "priority" fields with alert json object "description" and "severity":
subject-->description
priority --> severity // sev0 =high ,sev1=medium, sev2 =low
How can I achieve this using logic app?

Answer 1

After Parse JSON You can directly map its objects in the compose connector with the required fields. Below is my logic app flow.
You can use the below Code view to reproduce the same in your Logic app
