Header

Accept-Encoding: base64

jwt=eyJhbGciOiJSUzI1NiIs......uTonCA

Example REST request

curl -k --request POST 'https://example.com/authn-gcp/myorg/authenticate' --header 'Content-Type: application/x-www-form-urlencoded' --header "Accept-Encoding: base64" --data-urlencode 'jwt=eyJ0e......jjjkl'
