            The `notification` object defines the reminder notifications  sent
            to pending participants. It contains a `subject` and a `body` as
            nested parameters, and both fields support dynamic variables.


            **Dynamic Variables**

            You can personalize notification emails by referencing dynamic
            variables in the subject or body.

            Available variables:
                `envelope_name`: The name of the envelope being signed.
                `sender_name_or_email`: The sender’s name, or their email address if the name is not available.

            Syntax:

            To reference the variables, wrap them with `$()` in your message.
            Example: `$(envelope_name)`


            `notification` object example:

            ``` json

            {
                "notification": {
                    "subject": "$(sender_name_or_email) is requesting your signature",
                    "body": "Hi,\nPlease sign the $(envelope_name)\nThank you,\n$(sender_name_or_email)"
                }
            }

            ```


            **Note**: If the `notification` object is not provided in the
            request (or an empty object `{}` is sent), reminder emails will be
            sent using the default notification template that was configured
            when the envelope was created.
