Interface PresentationTemplateFragment<T>

The data associated with this fragment will be looked up in templateData map with this key.

Example:

const myTemplate = {
  body: {
    compositions: [{
      minTemplateAPIVersion: '1',
      layout: {
        type: CustomTemplateFragmentNames.text,
        dataKey: 'message',
      },
    }],
  },
}

const notificationOption: TemplateCustom = {
  //...
  templateOptions: myTemplate,
  tamplateData: {
    message: 'My Custom Notification Message',
  }
};

If a presentation template fragment is flagged as optional, The service will not require the fragment's dataKey to exist in templateData. If a fragment is optional and its data is missing, the fragment will be omitted quietly by the server.
