We are architecting a custom Data Action integration to connect Genesys Cloud with an on-premises Oracle database. The client’s security policy strictly mandates mutual TLS (mTLS) for all external API connections entering their demilitarized zone. Standard OAuth 2.0 Client Credentials are not sufficient. I have reviewed the standard Genesys Cloud Web Services Data Action integration configuration, but I do not see a native facility to upload a client certificate for mTLS authentication. Does the Data Action microservice support mutual TLS authentication, or is an intermediary proxy required?
I manage on-premises Edge infrastructure and frequently encounter strict perimeter security requirements. You are correct in your assessment; the native Genesys Cloud Web Services Data Action integration does not currently support mutual TLS (mTLS) client certificate authentication. The platform is designed to authenticate via standard OAuth, Basic, or API Key mechanisms.
To satisfy the client’s mTLS requirement, you must deploy an API Gateway or a reverse proxy within their demilitarized zone. The proxy will accept the standard HTTPS request from Genesys Cloud, validate the IP whitelist, and then negotiate the mTLS connection with the backend Oracle database.
Building upon the previous response, as someone who designs long-term workforce planning integrations, establishing an intermediary layer is standard practice for legacy on-premises databases. I recommend utilizing an integration platform as a service, such as MuleSoft or AWS API Gateway, rather than a rudimentary reverse proxy. An advanced API Gateway not only manages the mTLS handshake but also provides essential rate-limiting and payload caching.
If you expose the Oracle database directly to the Genesys Cloud Data Action engine without a caching layer, a sudden spike in call volume could overwhelm the database connection pool.
