我想要获取产品的库存信息，访问链接：transact.ti.com/.../products 得到的信息是401，返回信息如下：这是还没授权的意思吗？
{
"errors": [
{
"errorCode": "TI-API-0401",
"type": "Security",
"reason": "Invalid Credentials",
"message": "Invalid bearer token. Please contact your local IT support to verify authentication information. Once resolved, please resubmit request."
}
]
}
