🎯 Welcome to the Credentials & Integrations Section!

In this part of the course, we’ll cover one of the most important building blocks for creating AI agents and automations in n8n: connecting your workflows to external tools and APIs.

⚠️ Important: You don’t need to set up all of these accounts right now. This section is designed as a reference library — feel free to return to it whenever you're working on a project that requires a specific integration.

For most tools, especially with n8n Cloud, connecting is quick and easy. But for platforms like WhatsApp or Telegram, you may need to manually add API keys, even on paid plans—and occasionally refresh credentials to keep them active.

You’ll learn how to connect n8n to services like OpenAI, Grok, and DeepSeek, as well as messaging platforms like WhatsApp and Telegram.

We’ll also go over how to integrate Google services, which is necessary if you’re using a self-hosted version of n8n.

These tutorials include step-by-step guidance for beginners and advanced tips for more flexibility.
