# Get LWF Amount

GET https://api.salaryboxapp.com/v2/customer/v1/payroll/config/lwf

Works out the monthly employee and employer Labour Welfare Fund amounts for a state, as the app does while setting up a salary. Requires Payroll Pro. This is a calculator: it reads no staff data.

- `frequency` and `deduction_months` are `null`, and `is_deferred` is `false`, unless your company uses PT/LWF rule categories.
- `is_deferred` `true` means the fund is charged as a lump sum in the deduction months, so the monthly amounts are `0.00`.


Reference: https://docs.salarybox.in/api-reference/payroll/config-lwf-retrieve

## Authentication

- `Authorization` header (required) (prefixed with ` Api-Key   `) — Format: "Api-Key \{api-key}"

## Request

### Query parameters

- `state` (string, required) — Full state name. An unknown state returns `400`.
- `total_earning` (double, optional) — Monthly earnings. Optional. Some states work out the amount from it.
- `rule_category` (string, optional) — Rule category to use. Optional. Allowed only when PT/LWF rule categories are switched on for your company. See List PT and LWF Rule Categories.

## Response

### 200

The LWF amounts for the state.

- `message` (string, required)
- `status` (boolean, required)
- `data` (LwfAmountResponseData, required)

## Errors

### 400 Bad Request Error

A parameter is invalid.

- `message` (string, required)
- `status` (boolean, required)
- `errors` (map from string to any, optional, nullable)

### 403 Forbidden Error

Your plan does not include payroll.

- `message` (string, required)
- `status` (boolean, required)

## Types

### LwfAmountResponseData

- `state` (string, required)
- `rule_category` (string, required, nullable)
- `employee_contribution` (string, required) — Monthly amount, 2 decimals.
- `employer_contribution` (string, required) — Monthly amount, 2 decimals.
- `frequency` (string, required, nullable) — `null` unless the company uses rule categories.
- `deduction_months` (list of integer, required, nullable) — `null` unless the company uses rule categories.
- `is_deferred` (boolean, required) — `true` when charged as a lump sum in the deduction months, so the monthly amounts are `0.00`.
