                'content-type': "application/vnd.api+json",
                accept: "application/vnd.api+json"
        }).options({ allowUnknown: true }),
        payload : Joi.object().keys({
            data : Joi.object().keys({
                type: Joi.any().allow('BY_TEMPLATE').required(),
                attributes: Joi.object({
                    to : Joi.string().email().required(),
                    templateId : Joi.string().required(),
                    categories : Joi.array().items(Joi.string()),
                    variables : Joi.array().items(Joi.object().keys().max(1))
