Questions this record can answer
What changed for highlight integrations in September 2026?
September 18 added creating highlights on existing Reader documents; September 25 added editing and deleting highlights and returning notes and tags in lists. Check the API’s accepted fields: updating a highlight changes notes and tags, rather than replacing the highlighted passage.
Why can an API highlight creation fail even with a document ID?
Reader requires parent_id and content that matches a passage in the parent document. The API returns 400 without creating a highlight if the passage cannot be found. Fetch the stored document content before sending a quote; a paraphrase is not an exact match.
