In addition to accessing and retrieving media items after you upload them, you can also change their descriptions.
Required authorization scope
Changing descriptions of app-created content requires the
photoslibrary.edit.appcreateddata
scope. For more information on scopes, see
Authorization scopes.
Changing media item descriptions
To change a media item's description, make a media items update
call
with the identifier
of the media item, and include the new description in the request.
To change a media item's description, your app must have uploaded the media item, and the currently authenticated user must be the owner. Descriptions can be no more than 1,000 characters in length.
REST
Here's a PATCH request header to update a media item description:
PATCH https://photoslibrary.googleapis.com/v1/mediaItems/media-item-id?updateMask=description
This request determines what properties are being updated by including a
field mask, indicated by the updateMask
parameter in the URL.
Include the new description in the body of the request:
{ "description": "new-media-item-description" }
If successful, the response returns the updated media item:
{ "id": "media-item-id", "description": "new-media-item-description", "productUrl": "media-item-product-url", "baseUrl": "media-items-in-album", "mimeType": "mime-type-of-media", "mediaMetadata": { ... }, "contributorInfo": { ... }, "fileName": "item-filename" }
