我正在我的应用程序中实现DocuSign功能来签署PDF。 我关注以下链接： https://www.docusign.com/developer-center/api-overview 我们可以在使用上面链接中提到的步骤的同时在PDF中添加签名，但在第二次调用相同的方法签署新PDF时，我们在CreateEnvelope（）
行获取错误消息错误响应：{“errorCode”：“UNSPECIFIED_ERROR”，“message”： “输入字符串的格式不正确。” }
在创建信封时会产生错误。在这一行
EnvelopeSummary envelopeSummary = envelopesApi.CreateEnvelope（accountId，envDef）;
以下是我使用的代码
static string userName = Utility.GetConfigValue("docSignUserName");
static string password = Utility.GetConfigValue("docSignPassword");

你好CodingDawg这是JSON
{
"documents": [
{
"documentBase64": "",
"documentId": "1",
"name": "SignedFile.pdf"
}
],
"emailSubject": "Please sign this document",
"recipients": {
"signers": [
{
"clientUserId": "1234",
"email": "sagar.mali@tudip.com",
"name": "Sagar Mali",
"recipientId": "1",
"tabs": {
"signHereTabs": [
{
"documentId": "1",
"pageNumber": "1",
"recipientId": "1",
"xPosition": "192",
"yPosition": "679.968"
}
]
}
}
]
},
"status": "sent"
}
由于长度不支持，我们删除了基本64字符串。
答案 0 :(得分：1)
确保signHere.XPosition＆amp; signHere.YPosition值正确传递。
以下语句可以计算为十进制值。确保它是一个整数。
signHere.YPosition = (height - Convert.ToInt32(fieldPosition.position.Top + 25)).ToString();
请运行envelopeDefinition.ToJson()（Sdk documentation）并确保发布到DocuSign api的最终Json是正确的。
