+# Authorization in Angular UI
 
 OAuth is preconfigured in Angular application templates. So, when you start a project using the CLI (or Suite, for that matter), authorization already works. ABP Angular UI packages are using [angular-oauth2-oidc library](https://github.com/manfredsteyer/angular-oauth2-oidc#logging-in) for managing OAuth in the Angular client.
 You can find **OAuth configuration** in the _environment.ts_ files.

-## Service Proxies
+# Service Proxies
 
 Calling a REST endpoint from Angular applications is common. We usually create **services** matching server-side controllers and **interfaces** matching [DTOs](../../architecture/domain-driven-design/data-transfer-objects.md) to interact with the server. This often results in manually transforming C# code into TypeScript equivalents and that is unfortunate, if not intolerable.
