Slack is a popular workplace collaboration tool with over 10 million daily active users, and the Vonage-Slack integration allows developers to easily launch a customized live video experience within Slack without leaving their workspace. To get started, users need to sign up for a Vonage account and configure TokBox using specific commands such as `/tokbox`, `config`, and `remove`. This enables them to create unique links for live video meetings, set API keys and secrets, and remove the current configuration if needed. The integration aims to elevate the developer experience by providing a seamless way to launch a video session on Slack, making it an attractive option for teams looking to enhance their collaboration tools.
