# Show Thumbnail Customizations

`GET /medias/{mediaId}/customizations/thumbnail`

## Request

- Base URL: `https://api.wistia.com/modern`
- URL: `https://api.wistia.com/modern/medias/{mediaId}/customizations/thumbnail`
- Auth: HTTP bearer

Fetches the explicitly-set thumbnail customizations (still image URL, alt
text, fit strategy, and the looping video thumbnail / text-overlay plugins)
for the video.

## Requires api token with one of the following permissions
```
Read all folder and media data
```

Tokens with the "Act with a team member's permissions" permission
(`all:delegate_to_contact_permissions` scope) can also be used. Requests
made with such a token are authorized using the permissions of the
contact assigned to the token.

An [expiring access token](https://docs.wistia.com/reference/post_expiring-token)
created with the `all:delegate_to_contact_permissions` scope and an
authorization for this media can also be used; any permission granted on
the media allows reading its customizations.
