How do I Authenticate to AAD using Invoke-RestMethod with ClientCredential flow using certificate and get the token?
I tried to search for it but no success. I can authenticate with client Secret but I want to use cert for security purposes.
To get Access Token using client credential flow with using certificate.You need to generate a self singed certificate and need to upload in AzureAD application->ertificate&Secret.
You can refer this Post, Here they have explained in steps how you can generate the access token using the certificate.
