      description: 'The `on-behalf-of` header allows you to make API calls from a parent account on behalf of the parent''s Subusers or customer accounts. You will use the parent account''s API key when using this header. When making a call on behalf of a customer account, the property value should be "account-id" followed by the customer account''s ID (e.g., `on-behalf-of: account-id <account-id>`). When making a call on behalf of a Subuser, the property value should be the Subuser''s username (e.g., `on-behalf-of: <subuser-username>`). It is important to use the Base URL that corresponds to the region of the account or Subuser you specify in the `on-behalf-of` header. See [**On Behalf Of**](https://docs.sendgrid.com/api-reference/how-to-use-the-sendgrid-v3-api/on-behalf-of) for more information.'

      description: The number of items in the list to skip over before starting to retrieve the items for the requested page. The default `offset` of `0` represents the beginning of the list, i.e. the start of the first page. To request the second page of the list, set the `offset` to the page size as determined by `limit`. Use multiples of the page size as your `offset` to request further consecutive pages. E.g. assume your page size is set to `10`. An `offset` of `10` requests the second page, an `offset` of `20` requests the third page and so on, provided there are sufficiently many items in your list.
