Scim, authentication and OIN

Hi, I am trying to figure out what it takes to build a scim integration.
I will need to publish my app in the Okta Integration Network.
I think I read somewhere that when you want to do that you would need to implement OAuth2 as authentication for the scim api.
Bu I cannot seem to find that anymore.
Can anyone confirm or deny that?
Is it possible to use header auth? Or is OAuth2 mandatory when you want to publish in the OIN?
thanks Boris

Hi @borisnieuwenhuis

Except OAuth2, you can use also basic authentication and header token authentication. This details are available here.
