# Update a Project

> Updates an existing volunteer project. All required project fields must be supplied. Serving dates are upserted: a date with an existing id is updated, a date with no id is created, and a date is removed only when it is included with status 'deleted' — omitting a date from the request does NOT delete it. The project_type (dated vs. anytime) cannot be changed after creation.
