# Using the ReachBoost API

You can connect ReachBoost to almost any external system. With over 50 APIs, you can manage campaigns, add leads, retrieve data, and a lot more, all from your own tools.

**Note:** Create a separate API key for each source you connect — it keeps things organized and makes it easy to remove access for just one integration if something goes wrong

### Finding your API keys

Your API keys and workspace details live in one place, ready whenever you need to connect an external system.

**Step 1 - Open Integrations**
From your workspace, go to the **Integrations** item.

**Step 2 - Open the API keys tab**
Head to the **API keys** tab.

**Step 3 - Create a new key**
Click **Add new API key**. Give it a name that reflects the source you're connecting, so it's easy to identify later.

**Note:** An API key gives full access to your ReachBoost workspace. If a key is ever leaked or exposed, remove it from the API keys tab right away

### Using your key

Each API request needs both your API key and your Workspace UUID, which you'll also find in the API keys tab.
