Start Whereby Video Call from Mattermost

This workflow enables seamless video conferencing initiation from Mattermost. When triggered (likely via a slash command), it captures the channel ID and user name from the incoming webhook payload. It then constructs a Whereby room URL using the user's name (e.g., https://whereby.com/username) and posts a formatted message with an attachment linking to the room, allowing instant 'Join me in a video call' sharing.

Benefits include rapid ad-hoc meetings without manual room creation or scheduling tools, reducing friction in team communications. It's lightweight with just three nodes: Webhook trigger, data preparation via Set, and Mattermost response—ensuring low latency and reliability.

Ideal use cases: HR for quick employee check-ins, operations for on-the-fly team huddles, support teams collaborating with users, or any Mattermost-heavy organization needing instant video bridges. Companion to a blog post, it's easy to deploy and customize room names or add authentication.
