Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Use a delta query against the relevant assignment collection to detect assignment-level changes since the last sync token
Call educationClass: getRecentlyModifiedSubmissions to retrieve submissions whose grade or feedback changed since a given time
Store the returned delta link or timestamp as the checkpoint for the next incremental run
Reconcile changed submissions against locally cached grade records to update only what changed
Request app-only permissions with tenant admin consent if the integration should not depend on per-user delegated sign-in
Known gotchas
Delta query support is documented at the assignment level, not guaranteed at fine-grained submission-field granularity, which is why getRecentlyModifiedSubmissions exists as a complementary mechanism
App-only permissions require a tenant admin to grant consent up front; they cannot be self-consented by individual teachers or students
