Validate the azure-devops PAT - azure-devops

Question

I have created an PAT from azure devops. Now i have create a react app to handle all the api logics. I have a login screen now user need to enter the DEVOPS_TOKEN, ORGANISATION_NAME. How can i validate the user token at login. I couldn't find any api for validate the user.
Any suggestions would be helpful.

Answer 1

After a bit of investigation i found out a way to validate the user. There is an api that is available in Azure Devops: https://dev.azure.com/{ORGANISATION_NAME}/_apis/connectionData.
Need to pass the encoded token in header parameter that results the user authorization.
