延长请求

为现有的 TronSave 订单提交续期请求——使用你的 API 密钥（内部账户）或签名交易进行支付——并获取 orderId。

为你在步骤 1：获取可续期的代理中选择的代理（委托）进行续期。支持两种支付方式：

方式 1 — API 密钥： 使用 TronSave API 密钥在预先充值的内部账户上授权续期；无需对每笔订单进行链上签名。
方式 2 — 签名交易： 使用你自己的私钥对续期进行签名，并在链上完成结算。

两种方式使用同一个端点，成功时都会返回一个 orderId。

此方式不需要 API 密钥。你需要使用自己的私钥构建并签名支付交易，并将其作为 signedTx 包含在请求中。

请求体

字段

类型

说明

receiver*

String

接收资源的接收地址。

后续步骤

通过获取可续期的代理开始流程。
使用获取签名交易构建签名交易。
在调用 API 之前，先设置身份验证。
