# Request Update Node Parameters

The **Request Update** node (`action_request_update`) updates ticket or chat fields (subject, priority, status, tags, etc.) without operator involvement. Typically used after collecting data from the client or after conditional branching. In **Node Inspector** (right panel) the following sections are available:

## Fields to Update (templateConfig)

Parameters are set dynamically via **JSON config** (`json_config`). Available fields depend on request type and instance settings. Typical fields:

- **subject** — request subject.
- **priority** — priority (low, medium, high, etc.).
- **status** — ticket status.
- **tags** — request or client tags.
- **request_type** — request type.
- **custom fields** — additional fields configured in the system.

Values can be static or variable via placeholders (e.g., `{{client_name}}`).

## JSON Config (json_config)

- **Structure** — object with keys (field names) and values (text, placeholders, expressions).
- **Placeholders** — variables from previous nodes are supported (e.g., `{{outputVariable}}`).
- Config is passed to the `action_request_update` action and defines which fields to update and what values to set.

**Example:** update request subject to value entered by client in previous node:
```json
{
  "subject": "{{client_subject}}"
}
```
