标签： paypal postman

我正在遵循有关如何使用Postman从Paypal获取访问令牌的说明。

我不断收到此错误消息：

  

“错误”：“ unsupported_grant_type”，“错误描述”：“赠款类型   是NULL”

这是我的邮递员设置：

网址：https://api.sandbox.paypal.com/v1/oauth2/token

授权：用户名：client_id ...密码：秘密...

标题：内容类型-> application / x-www-form-urlencoded

body：采用表单密码

key: grant_type
value: client_credentials
