Questions tagged [vonage]

For questions relating to usage of the Vonage (formerly Nexmo and OpenTok) communications APIs for Messaging (SMS, MMS, social chats apps such as Facebook Messenger and WhatsApp), Verify, Voice, and Video, as well as associated tooling and language-specific SDKs.

This tag is to be used when asking questions about any of the Communication APIs that are provided by Vonage (formerly Nexmo and OpenTok). These include (but are not limited to) Voice, Video and SMS.

For more information about these APIs, check out the Vonage documentation.

Community Further help can be found via Vonage Developer communities, where you can ask questions and learn more about the Vonage APIs and SDKs. These include Slack, Twitter and Youtube.
