# Update Presentation

Update the metadata (such as description) of an existing presentation deck.

## When to update

Update presentation details when you want to refine the description so the agent better understands when to trigger and present slides from this deck during user queries.

## Parameters

* `id` (path, required): unique identifier of the presentation

## Request Body

* `description` (string, optional): updated description detailing the topics covered in the deck

## Example

```bash theme={null}
curl --request PATCH \
  --url https://api.trugen.ai/v1/ext/presentation/1411f164-fe94-4a4b-9b1b-027a9929f95d \
  --header 'Content-Type: application/json' \
  --header 'x-api-key: YOUR_API_KEY' \
  --data '{
    "description": "Updated sales pitch deck for Q3 & Q4"
  }'
```
