# PLAN_FEATURE_REQUIRED

> HTTP 403, from 3 operations of the Admin API.

Its problem `type`: `https://developers.tassyir.io/errors/plan-feature-required`.

## What to do

HTTP 403. The merchant's plan lacks the feature (`feature`), such as stock at a
chosen location. Do without it, or tell the merchant.

## Answered by

HTTP 403, from:

* [`GET /inventory-levels`](/api-reference/admin/inventory/list-stock-levels)
* [`GET /inventory-levels/{id}`](/api-reference/admin/inventory/get-a-stock-level)
* [`POST /inventory-levels/{id}/adjust`](/api-reference/admin/inventory/correct-a-stock-count)

The shape of every problem, and how `@tassyir/app` reports it: [Errors](/guides/errors).
