`, and ``. If other tags are used, the editor may error.
```javascript
window.Pylon("showNewMessage", "I'm experiencing an issue with syncing from Google Sheets to Email and could use some assistance", { isHtml: true});
```
To set custom fields on just this conversation, pass `customFields`. These are merged over any values set with [`setNewIssueCustomFields`](#window-pylon-setnewissuecustomfields).
```javascript
window.Pylon("showNewMessage", "Sync failed for workspace 123", {
customFields: { workspace_id: "123" },
});
```
The message can be at most 2,500 characters. `showNewMessage` does nothing when the Chat module is turned off for the user.
## `window.Pylon("showIssue", "string")`
Opens the chat window to an existing conversation, by issue ID. Use it with `onActiveIssueChange` or `getCurrentIssue` to restore the conversation a user had open, for example after a page reload.
```javascript
window.Pylon("showIssue", "3f2b6c1e-8a4d-4c1b-9e2f-1a2b3c4d5e6f");
```
## `window.Pylon("getCurrentIssue")`
Returns the conversation open in the chat window as `{ issueID, issueNumber }`, or `null` if none is open. Unlike other methods, this returns a value directly, so call it after the widget has loaded (calls queued before then return nothing).
```javascript
const current = window.Pylon("getCurrentIssue");
```
## `window.Pylon("onActiveIssueChange")`
Pass in a callback function that is called when the open conversation changes. It receives `{ issueID, issueNumber }`, or `null` when the user leaves the conversation. If a conversation is already open when you register the callback, it is called right away. Pass in `null` to remove the existing callback.
```javascript
window.Pylon("onActiveIssueChange", function (issue) {
if (issue) {
sessionStorage.setItem("pylonIssueID", issue.issueID);
} else {
sessionStorage.removeItem("pylonIssueID");
}
});
const savedIssueID = sessionStorage.getItem("pylonIssueID");
if (savedIssueID) {
window.Pylon("showIssue", savedIssueID);
}
```
## `window.Pylon("showTicketForm", "string")`
Navigates the chat bubble to a specified ticket form, by ticket form slug.
```javascript
window.Pylon("showTicketForm", "test_ticket_form");
```
The ticket form slug can be found in the edit ticket form page under `Form Slug`.
## `window.Pylon("showKnowledgeBaseArticle", "string")`
Navigates the chat bubble to a specified knowledge base article, by article ID.
```javascript
window.Pylon("showKnowledgeBaseArticle", "123456789");
```
The article ID can be found in the URL of the public view of a knowledge base article, as the first set of numbers following `articles/`. In the following example, the identifier is "1234567899"
