# Updating Client Details via Partial PATCH Requests
> This document explains how to review the API documentation for performing partial updates to a client resource using JSON Patch operations, including understanding the required path parameters and the structure of the request body.
### Step 1: Review Required Path Parameters
Locate the API documentation section that describes partial client updates (PATCH endpoint for client resources).
Identify and review the path parameters needed to target a specific client record, focusing on:
* **tenantId** – the identifier of the tenant or organization that owns the client.
* **clientId** – the unique identifier of the client to be updated.
Ensure you understand that both parameters are mandatory to correctly identify the target resource.

### Step 2: Examine the JSON Patch Request Body Example
Scroll down in the documentation to the **Request body** section and inspect the JSON Patch example.
Review each operation in the example, noting how it uses standard JSON Patch fields such as `op`, `path`, and `value` to partially update client details, including:
* **Fullname** (e.g., `/Fullname`)
* **Gender** (e.g., `/Gender`)
* **Email** (e.g., `/Email`)
* **Mobile details** (e.g., `/MobileNumber`, `/CountryCode`)
* **Website** (e.g., `/Website`)
* **Online status** (e.g., `/IsOnline`)
* **Notification preferences** (e.g., `/Notifications/Email`, `/Notifications/SMS`)
Continue reviewing until you reach the end of the sample payload so you understand all supported fields and how to structure your patch operations.
