红帽全球峰会46.14. 使用 Salesforce Composite API 提交多个链请求
复合 操作允许提交最多 25 个请求，这些请求可串联前面请求中生成的实例标识符，可在后续请求中使用。单个请求和响应与提供的 参考 相关联。
注意
复合 API 仅支持 JSON 载荷。
注意
与批处理 API 一样，结果可能因 API 和 API 不同，因此请求的结果会作为 java.lang.Object 提供。在大多数情况下，结果将是 java.util.Map，它带有字符串键和值，或其他 java.util.Map 作为值。以 JSON 格式发出请求会保存一些类型信息（例如，它知道哪个值是字符串的值，以及数字是什么）。
让我们来看看：

// first insert operation via an external id
final Account updateAccount = new TestAccount();
