# Discount codes are now case-insensitive

Customers can now enter discount codes with any casing, for example `blackfriday`, `BLACKFRIDAY`, or `blackFriday`. The Paddle API no longer treats codes against the discount entity as case-sensitive.

---

## What's new?

We've updated the Paddle platform so that discount codes are case-insensitive across the Paddle API and Paddle.js.

## How it works

When creating a [discount](https://developer.paddle.com/api-reference/discounts/overview.md), you can set a discount code to let customers apply a discount at checkout easily.

Previously, discount codes were case-sensitive. For example, `blackfriday`, `BLACKFRIDAY`, and `blackFriday` were interpreted as different discount codes when creating a discount and when entered at checkout.

With this update, discount codes are now case-insensitive. This means discounts are applied when the correct code is entered, regardless of the casing. This makes for a better customer experience and reduces the likelihood of checkout abandonment.

## Next steps

This change is available now in version `1` of the Paddle API and in the latest version of Paddle.js. You don't need to do anything to get the latest version of Paddle.js — we serve the latest version automatically.

You shouldn't need to make any changes to your implementation. A small number of Paddle platform users had discounts that shared the same `code` with different casing. We reached out to those users directly.
