# Shopify Function configurations now use target identifiers

As of API version 2023-10 and Shopify CLI 3.49.5, [Shopify Functions](https://shopify.dev/docs/apps/functions) configuration now uses [targets](https://shopify.dev/docs/apps/app-extensions/configuration#targets) to identify backend extensibility points in Shopify, so that configuring a function is now more like configuring other app extensions.

All Shopify Function APIs now support `[targeting]` configuration, with an extension target mapping to a specific WebAssembly export.

```
[[extensions.targeting]]
target = "purchase.validation.run"
input_query = "src/run.graphql"
export = "run"
```

Existing functions without `targeting` specified will continue to execute and deploy without any changes required. Use of `targeting` requires [upgrading](https://shopify.dev/docs/apps/tools/cli#upgrade-shopify-cli) Shopify CLI to 3.49.4 or higher.
