尝试使用SOBO获取发件人查看URL时INVALID_REQUEST_BODY

Question

我代表（SOBO）使用send创建一个信封，工作正常。

我能够获得envelopeId。但是，当我尝试使用用于创建信封的基本URL并添加添加的＆＃34; / {envelopeId} / views / sender＆＃34;在发布之前我得到了INVALID_REQUEST_BODY。

文档显示请求正文只有一个项目... returnUrl如此处所示https://iodocs.docusign.com/#＆＃34; Views - ＆gt;发件人＆＃34;节

'POST http://{server}/restapi/{apiVersion}/accounts/{accountId}/envelopes/{envelopeId}/views/sender

            '/envelopes is already part of the base url because of creation of the envelope
            url = url + "/" & strEnvelopeID & "/views/sender"
strBody = "<returnUrl>https://www.google.com</returnUrl>"
request = initializeRequest(url, "POST", strBody, strUserName, strPassword, strIntegratorKey)
