I am working on a Business SaaS solution and my data is siloed using a tenant_id column. I am setting up REST APIs using ORDS (v24). The application will provide the ability to POST and GET the subscribers data. Each subscriber will be provided their own set of credentials for the REST API. In calls to the API, I am requiring the tenant_id to be passed in via the headers. It occurs to me that even though I am securing the API behind a set of credentials, there is nothing to prevent the subscriber from using their credentials to access the API, but spoof their tenant_id in the headers by simply guessing a different tenant_id. Is there a way in ORDS to identify the user accessing the API so that I can map that user to the tenant_id? If not, I already activate a fake application user primarily for the purposes of logging the transactions. So, I've considered securing that user with a password and requiring the password to also be passed in the headers. I appreciate your advice on the best approach to use.
