# Scopes

> How to use Common Model Scopes to restrict which models and fields Merge syncs. Configure scopes globally or per Linked Account to limit data access.

---

Scopes allows for precise control over data permissions, ensuring that only relevant Common Models and fields are synced through Merge. Disabling a Common Model Scope will also disable all of its associated fields.

Below, you'll find endpoints related to two levels of Scopes.

* **Default Scopes** apply to new Linked Accounts for a given category
* **Linked Account Scopes** apply only to a specific end user (Linked Account).

The Scopes applied to a Linked Account are first determined by the Linked Account Scopes, and fall back to Default Scopes for any that haven't been set. [Learn More](https://help.merge.dev/en/articles/5950052-common-model-and-field-scopes).
