Readwise refreshes review emails and Reader highlight creation
Availability and conditions refer to the original announcement.
The update, in brief
The September 18 roundup introduces redesigned review emails and lets the Reader API create highlights anchored to an existing document, with optional notes and tags.
What’s new
- Review emails link directly to editing, tagging and sharing highlights.
- Create document highlights through the Reader API.
Availability details
Enable the email design in Readwise's web email preferences; the old design remains selectable. The API requires a Readwise access token. September 18 is the roundup date.
Questions this record can answer
What must a create-highlight request contain?
Use an authenticated Reader API request with parent_id for an existing document and content matching its stored passage. Notes and tags are optional. If the passage is not found, the API returns 400 and creates nothing; check the saved content before retrying.
