Select the “Update a row” action.

Add the Tablename, RowId and Account Name:-
Table Name: – Select a table name. 
Row ID: – Here you have to pass the GUID of the record.    
Account Name: -Add the name that you want to set.

5) Add “HTTP Response” action to send the response back to the [removed]- 
Status Code: -200(Successful responses) 
Body: – Enter the message you want to return for a successful response. 

JavaScript Code:-

//Request
CallFlow(formContext) {

let RecordID = formContext.data.entity.getId().replace("{", "").replace("}", "");
let params = {
"Guid": RecordID,
}

let url = "https://prod-1.westus.00"; //flow url
let req = new XMLHttpRequest();
req.open("POST", url, true);
req.setRequestHeader('Content-Type', 'application/json');
req.send(JSON.stringify(params));
//@ts-ignore
Xrm.Utility.showProgressIndicator("Please Wait for the moment...");//here get the response

//response
req.onreadystatechange = function () {
if (this.readyState === 4) {
req.onreadystatechange = null;
if (this.status === 200) {
var Account_name = JSON.parse(this.response);
//@ts-ignore
Accountsobj.showAlertMessage("Account has been Updated... " + Account_name.Message);
}
else {
Accountsobj.showAlertMessage("Error in flow ");
}
}
formContext.data.refresh(true);
};
}
//Show the alert box after the account has updated
showAlertMessage(message) {
try {
let alertStrings = { confirmButtonLabel: "OK", text: message };
let alertOptions = { height: 120, width: 350 };
//@ts-ignore
Xrm.Navigation.openAlertDialog(alertStrings, alertOptions).then(
function (success) {
},
function (error) {
Accountsobj.showAlertMessage(error.message);
}
);
} catch (e) {
Accountsobj.showAlertMessage(e.message);
//@ts-ignore
Xrm.Utility.closeProgressIndicator();
}
}
}
let Accountsobj = new CRM.Library.Call_Flow();
