Segments

PUT (update) a Segment

Use this method to update an existing segment's name (name) and/or contact selection criteria (segment_criteria). You must specify both the name and the segment_criteria in the request body, even if you don't plan to update both. The segment's name must be unique and the JSON must be valid (requires single-string escaped JSON). To avoid returning a 400 error response, when specifying the segment_criteria do not request more than 500 email campaigns or a date range greater than 1825 days (5 years) be evaluated. For more use case information, see Update Segment Details in the API guide.
