Upload Media for Google Photos
See more Google Photos Examples
Demonstrates how to upload a media file (such as a JPG image) that will be placed in a Google Photos album. Uploading is a two-step process:
- Upload the raw bytes to a Google Server. This doesn't result in any media items being created in the user’s Google Photos account. Instead, it returns an upload token which identifies the uploaded bytes.
- Use the upload token to create the media item in the user’s Google Photos account. You can choose whether the media should be also added to a specific album.
This example shows step 1.
