Why I get Internet Explorer enhanced security error message in Chrome if I call VSO API from Angularjs SPA?
I found that this happened to me when my PAT was wrong due to a copy and paste error.
Looks like you are probably failing authentication because you didn't base64 encode the bearer token.
I had this same issue. I verified this in postman as follows...
I didn't have to base64 encode my PAT.I found that I just needed to double check that my PAT had the right access.I passed the data as Basic Auth.Username: "whatever the hell you want"Password: PAT
Response: 200 👍
Prefix your Personal Access Token(PAT) with :(colon). then Base 64 encode it.
Eg:
If "myaccesstoken" is my PAT,
Apply base 64 encoder to ":myaccesstoken"
In the Authorization header, place your base encoded string as,
Authorization : Basic MyColonPrefixedBase64String
