This integration was developed primarily using the documentation provided by BigID at https://api.bigid.com/. Please reference it for questions specific to any of their endpoints.
BigID provides a sandbox at https://sandbox.bigid.tools/api/v1/ that can be used to test any changes to this integration.
We currently use user tokens to then generate a session token for authentication. A user token for BigID's sandbox can be generated for use via a small tool provided on this page https://developer.bigid.com/wiki/BigID_API/API_Tutorial#Token_Authentication.
Documentation on session token authentication can be found at https://api.bigid.com/index-session-tokens.html#post-/sessions
