List Deleted Custom Fields

When a custom field is deleted, it is not actually removed from the database. Instead, it is marked as deleted and is no longer used.

This endpoint will return the list of deleted custom fields that were associated with the specified mailing list or organization.

URL

GET https://app.kasplo.com/ga/api/v2/mailing_lists/:mailing_list_id/custom_fields/deleted

Response

The response will contain the same fields as listed in the Attributes section above – but with one additional field ( deleted_at). This value will be the time at which the custom field was deleted.
