It supports two-way SMS, inbound webhooks, short codes, and toll-free numbers, but not MMS. Vonage describes uses such as appointment and delivery notifications, customer engagement, and private messaging between users. Its developer tools include SDKs for Node.js, Python, Java, Kotlin, Ruby, PHP, and .NET, plus CLI tools, tutorials, getting-started resources, and a community. Adaptive Routing can reroute messages to optimize delivery. The documentation describes signing outgoing messages and verifying incoming signatures to check origin and detect tampering or replay.
