passing a parameter through AAD authentication to power bi api

I have a webapp that begins authentication with AAD and another that gets redirected to and

gets the certificate, then access powerbi api to create a dataset.

Is it possible to pass a parameter to the webapp that begins the AAD authorization steps

such that it would be passed through to the callback that AAD redirects to after the login.

I want to pass a value to use when I get authenticated to use powerbi api. e.g. another application

wants to export file data to powerbi, so I want to pass a filename. when I try this,

the redirect doesn't forward my parameter to the second webapp (that gets the certificate). How

do you recommend getting around this? Thanks for any help.
