How do I set the Start date and Due date on a folder?

Question

Looking at the wrike API, I don't see a way to set the startDate and dueDate fields on the folder update endpoint.  There's not `dates` object like there is for tasks.  Is there a way to manually set these values via the API?

Hi @Matthew Lauber folders doesn't have start and due date, but projects yes.

To pass it by API the structure looks like this:

PUT https://www.wrike.com/api/v4/folders/{folderId}

With the body (URL-encoded):

project={"startDate":"2025-06-01","endDate":"2025-09-30"}

Or in JSON body terms:

json

{
  "project": {
    "startDate": "2025-06-01",
    "endDate": "2025-09-30"
  }
}
