Mattermost

API

Open-source collaboration API for developer teams

Overview

The Mattermost API is a RESTful interface for interacting with the open-source developer collaboration platform. It uses JSON for request/response formats and offers endpoints for managing teams, channels, users, messages, webhooks, and integrations. Developers can build chatbots, automate workflow alerts (e.g., CI/CD notifications), sync data with tools like Jira/GitHub, and customize collaboration workflows. It also supports real-time updates via WebSockets, ideal for live team communication and event-driven integrations.

Example Integration (JavaScript)

script.js JS


fetch('https://api.mattermost.com/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
