# What's New

<br />

## Authorization Code Rate Limiting

We’ve introduced **auto-scaling rate limits** for **Authorization Code** applications (this does **not** apply to Client Credentials apps):

* Baseline: 10 calls per minute per account.
* The limit scales with the number of accounts a single consent granter has granted to the app.

**Examples**

* If **Bob** granted consent to accounts 1, 2, and 3 → Bob’s app limit = 3 \* 10 = 30 calls per minute (shared across those three accounts). Bob could use all 30 calls per minute on one account, but that reduces what’s available for the others in that minute.
* If **Alice** consented to account 4 and **Jen** consented to account 5 → the app can call “as Alice” at **10 calls per minute** and “as Jen” at **10 calls per minute** (limits are per consent granter).

**Guidance:** Application owners should align consent granters strategically to scale limits according to expected operations.

## Product Sets Moves to Stable

The **Product Sets** endpoint has moved from **Preview** to **Stable**.

A Product Set is a subset of your product catalog that can be featured in dynamic ads.

* Create Product Sets using rule-based conditions on catalog attributes (conditions are additive, like an **AND** operator).
* Apply a Product Set to an Ad as a filter. After you do, Ads will display only products from that Product Set.
