Vonage SMS API
What Vonage SMS API is
Vonage SMS API lets applications send text messages and look up messages associated with an account or its virtual numbers. It supports two-way SMS, inbound webhooks, short codes, and toll-free numbers; MMS is not supported. Vonage describes uses that include appointment and delivery alerts, customer engagement, and private messages between users. Its Adaptive Routing feature can reroute messages to optimize delivery, and Vonage says its developer tools can reach 6 billion people in practically every country.
Developers can use SDKs for Node.js, Python, Java, Kotlin, Ruby, PHP, and .NET, as well as CLI tools. Getting-started materials, tutorials, a community, and other tools are available. The documentation describes signing outgoing messages and checking signatures on incoming messages to confirm origin and detect tampering or replay. Vonage lists ISO 27001, SOC 2 Type II, HIPAA Attestation of Compliance, and CSA Star for its Core API services, including SMS and Voice. The API is usage-based, with rates varying by country and number type; pricing is on request. There is no free plan, but a free trial and free credit without a credit card are offered. Vonage was founded in 2001 and is headquartered in Holmdel, New Jersey.
