Sync a folder

Sync a folder from Google Drive, Microsoft (OneDrive or SharePoint), Dropbox, Box, or Egnyte into a project's, account's, contact's, or intake's files, or the Library: pass exactly one of projectId, accountId, contactId, intakeId, or library, and folderId to place it inside a folder there. The sync uses your own connection to the provider, and Parley keeps the folder's files up to date in the background; they can't be changed in Parley. You sync a folder into a location once, while other people can sync the same folder there, each seeing what their own account can open: syncing it again into the same folder returns your existing sync, and into another folder of the location returns 409 FOLDER_ALREADY_SYNCED. Returns 409 CONNECTION_REQUIRED when you haven't connected the provider or must reconnect it, 400 INVALID_REFERENCE when the folder doesn't exist at the provider, isn't a folder, or your connection can't open it, and 429 TOO_MANY_REQUESTS when Egnyte's daily limit for your account is used up, until it resets at midnight UTC.
