A valid Databridge Pro username and password are required for API basic authorization. The credentials entered are validated against the Databridge Pro system.
A Service Account user can be created in Databridge Pro and used for API authorization. Service Account users are restricted, only having access to the Inbound Messages API. This user will not have access to the tenant canvas and will be unable to log into Databridge Pro.
See Adding service account users in Databridge Pro Help for details on how to add this user type
The Inbound Messages API does not reference the EAM user database and does not require
an EAM Connector user.
