Supported types: TEXT, NUMBER, DATE; these inputs are sent as lowercase API values. Use **action** to specify the operation: `create`, `update`, or `delete`. Existing fields can be viewed using the Get List tool.

Retrieve all email campaigns. Returns campaign details including status, subject, sender info, and target lists. Campaigns are read-only via the API.

Delete List

Permanently delete a contact list and all its contacts, custom fields, and tags. This action cannot be undone.
