# Regex dello strumento di espressione corrispondente

Lo strumento dell'espressione di corrispondenza si usa quando conosci una parte delle combinazioni di caratteri nei SKU, nelle categorie o nei codici promozionali dei tuoi prodotti e desideri abbinare queste combinazioni di caratteri agli SKU, alle categorie o ai codici promozionali passati con le tue conversioni. Dovresti usare questo strumento solo quando non hai l'elenco completo degli elementi in un [elenco di eccezioni](/brand/it/what-would-you-like-to-learn-about/account-administration/program-settings/exception-lists/create-category-and-sku-exception-lists.md).

1. Nella barra di navigazione superiore, seleziona ![](https://1043985218-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FwMLlMoFBtKJa8ptd3zaw%2Fuploads%2F210dEQa93qyQgoJDkieL%2FUser%20profile.svg?alt=media\&token=f84c5b17-fae4-4a30-990a-9de5e57a150b) **\[Profilo utente] → Impostazioni**.
2. Nella colonna di destra, sotto *Elenchi di eccezioni*, seleziona *Elenchi di eccezioni* sezione, seleziona **SKU**.
3. Seleziona **Aggiungi nuovo elenco SKU**.
4. Seleziona **Mostra impostazioni avanzate** ![](https://1043985218-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FwMLlMoFBtKJa8ptd3zaw%2Fuploads%2Fgit-blob-500f241687470b7f2c6cf43ec949c2463692cd19%2F0323174d38f3b23e95ed28b6734e6af44b570eec2eecb0ea9f2e0f064962b5fb.svg?alt=media).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.impact.com/brand/it/what-would-you-like-to-learn-about/platform-features/promo-codes/regular-expression/match-expression-tool-regex.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
