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. The Vonage APIs can be accessed via first-party supported SDKs for a range of popular languages and platforms or called directly via HTTP requests.

If you have a question specifically relating to a specific SDK or platform, please make sure to include that platform’s tag in your question as well (for example, Java, Android, PHP, Python etc.).

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.
