If you're setting up OTTO, connecting an integration, or working with a developer, you may be asked for either your UUID or your API Key. While they may sound similar, they serve very different purposes and are located in different areas of the dashboard. This guide shows you exactly where to find each one.

# **🆔 How to Find Your UUID (OTTO Pixel UUID)**

Your UUID is part of your OTTO Pixel installation script. It identifies your specific project installation. Navigate to Left Sidebar → OTTO SEO → All Sites, select your project, then open Installation Guide → Custom Installation.

Under Step 1: Copy Your Pixel Script, you'll see a script block containing a data-uuid attribute formatted like XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX. That value is your UUID.

# **🧠 What the UUID Is Used For**

It identifies your OTTO installation, connects your website to your specific project, is unique per project, and is automatically generated. You'll typically need it when verifying pixel installation, troubleshooting OTTO setup, or working with technical support.

# **🔐 How to Find Your API Key**

Your API Key is different from your UUID. It's used for integrations and external connections to Search Atlas. Navigate to Top Right → Click Your Profile Name → Settings → API Keys.

You'll see a section titled Search Atlas API Key, with a long alphanumeric key. That string is your API Key.

# **🧠 What the API Key Is Used For**

It's used for connecting third-party tools, API-based integrations, automation workflows, and external platform connections. Your API Key is sensitive — do not share it publicly.

# **⚖️ UUID vs API Key — What's the Difference?**

The UUID is found in the OTTO Installation Guide, is project-specific, is used for pixel installation, and lives inside a script tag. The API Key is found in Account Settings, is account-level, is used for integrations, and is displayed in the API Keys panel.

**Quick summary:** Need to install or verify OTTO? Get your UUID. Connecting an integration or using API access? Get your API Key.
