Method: sessions.create

  • This endpoint creates a session for users to select photos and videos for third-party access.

  • A FAILED_PRECONDITION error occurs if the user lacks an active Google Photos account.

  • Excessive session creation leads to a RESOURCE_EXHAUSTED error, though unlikely under normal use.

  • Clients should call sessions.delete after each session to avoid exceeding resource limits.

  • Requires the https://www.googleapis.com/auth/photospicker.mediaitems.readonly OAuth scope for authorization.

Generates a new session during which the user can pick photos and videos for third-party access.

If the user doesn't have an active Google Photos account, a FAILED_PRECONDITION error is returned.

If the client application creates too many sessions per user, a RESOURCE_EXHAUSTED error is returned. Clients are unlikely to reach these limits under normal circumstances. However, clients are still recommended to call sessions.delete after each session, to proactively stay within resource limits.

Once a user taps the Done button to complete a picking session, the pickerUri will no longer work. Create a new session to allow the user to pick more photos.
