How can I get only the last message in the attached thread conversation from the "ticket conversation"?

client.get("ticket.conversation").then((data) => {

// get most recent conversation object
const arrItem = data["ticket.conversation"].at(-1);

// get message content
const lastMsg = arrItem.message.content;

console.log(lastMsg);
});

Hi Jigar,
 
Here's another code sample that makes a call to the Ticket Comments API and pulls only the plain text body from the most recent message. Let me know if this is closer to what you were hoping to do.
 

client.get("ticket.id").then((ticketId) => {

  // call the tickets API to get a list of comments on the ticket
  client.request(`/api/v2/tickets/${ticketId["ticket.id"]}/comments`).then((data) => {
  
  // get most recent comment object
  const arrItem = data.comments.at(-1);

  // get plain text content
  const lastMsg = arrItem.plain_body;

  console.log(lastMsg);
 });
});
