# 删除水印模板
通过指定水印模板ID删除用户自定义的水印模板。
#### 核心代码
```
// 发送删除水印配置模板请求给媒体处理服务
DeleteWatermarkTemplateRequest req = new DeleteWatermarkTemplateRequest().withTemplateId(215728);
DeleteWatermarkTemplateResponse rsp = initMpcClient().deleteWatermarkTemplate(req);
// 打印返回消息
System.out.println("httpCode=" + rsp.getHttpStatusCode() + ", rsp=" + JsonUtils.toJSON(rsp));
```
