# Access, Permissions, and Settings Management APIs

The **Access, Permissions, and Settings Management APIs** enable secure control over user roles, permissions, and system configurations within the platform. These APIs help enforce role-based access control (RBAC), define security policies, and dynamically manage system settings to ensure secure and efficient operations across services.

***

#### **1. Role Management**

Roles define access privileges for users interacting with the platform. The Role Management APIs allow organizations to create, update, and assign roles to users, ensuring appropriate access to various services.

For example, an admin can assign a **"Finance Manager"** role with access to ledger transactions while restricting the ability to modify system settings.

***

#### **2. Permissions Management**

Permissions specify what actions a role or user can perform within the system. The Permissions Management APIs enforce fine-grained security policies to protect sensitive data and system functionality.

For instance, a **customer support agent** may have permission to view account balances but not to approve financial transactions.

***

#### **3. Settings Management**

Settings control platform-wide and service-specific configurations, such as API rate limits, authentication methods, and logging preferences. The Settings Management APIs allow real-time modifications without requiring redeployment.

For example, an organization can dynamically adjust **security settings** by enforcing two-factor authentication (2FA) for all users.

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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.xyb.co/xyb-platform-1/xyb-ledger/api-reference-guides/access-permissions-and-settings-management-apis.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
