Optus SMS Suite SMPP API is one of 15 APIs that [Optus](https://apis.io/providers/optus/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include SMS, Messaging, and SMPP. The published artifact set on APIs.io includes API documentation.

Direct SMSC connectivity over SMPP 3.3 and 3.4 with mandatory TLS, offering high-throughput binary messaging, custom character encoding, and detailed delivery reporting. A wire protocol rather than an HTTP API — no OpenAPI definition exists or is expected.
