Template Editor Sessions allow you to embed the PostGrid Template Editor in your application and receive real-time events when a template is saved or when an error occurs.
## Overview
A [Template Editor Session](https://docs.postgrid.com/#6b82eab7-4f09-42b4-b63e-cd73a3f2182a) is launched inside an iframe. When users save the template the editor sends structured events to the parent application using the browser’s [postMessage](https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage) API.
Your application is responsible for: • Embedding the editor • Listening for editor events • Handling success and error states
## Editor Event Types
When saved the editor emits the following events.
### Saved:
```
{
type: 'template_saved';
templateID: 'template_ayfqzhKTfcPLJcEhdndZrZ';
}
```
### Error:
```
{
type: EditorEventType.TEMPLATE_SAVE_ERROR;
templateID: 'template_save_error;
error: 'Failed to save template';
}
```
Your application can listen for events using the browser’s message event.
