# What is a Handle ID?
Where to find a Handle in Platter+
A **handle** is a unique identifier used to connect an app block (like a Platter+ extension) to your Shopify Checkout. Think of it as a label that Shopify uses to recognize and display the app block in the correct spot during checkout.
### Why are Handles useful?
Handles make the setup process seamless and reliable:
1. **Quick Installation**: Instead of manually configuring or searching for an app block, copying and pasting the handle ensures the correct extension gets added immediately.
2. **Error-Free**: Because each handle is unique, it prevents confusion or mistakes when enabling multiple checkout extensions.
3. **Flexibility**: You can easily enable, disable, or customize app blocks by pasting their handles into the Shopify Checkout Editor, giving you more control over the checkout experience.

### Where can I find the Handle for the extensions I have configured?
In the **Extensions** tab, you can find the Handle IDs for all of the extensions you have saved.
To save a Handle from this view, simple click the `+` icon and the Handle will be copied to your clipboard.
