[safaa.oumhand]

Hello,

I'm using basic Auth (with VBA ) for API Rest .

1. I Generate an API token for Jira using my Atlassian Account
2. Build a string of the form useremail:api_token.
3. BASE64 encode the string.
4. it works for with my outlook account but i'm getting the following error while using the google account :

Status : 401

Error Message : You are not authenticated. Authentication required to perform this operation

while i'm getting 200 status using postman

Any thoughts??
