# API04006: Resource Not Found

## What This Means[​](#what-this-means "Direct link to What This Means")

The server could not find the requested resource. This typically corresponds to an HTTP 404 status code, indicating the product, order, customer, or other resource you're trying to access doesn't exist.

## Common Causes[​](#common-causes "Direct link to Common Causes")

* **Record deleted** — The resource was deleted on the server
* **Wrong ID** — An incorrect or outdated ID is being used
* **Sync issues** — Local data references a resource that no longer exists
* **URL misconfiguration** — The API endpoint is incorrect
* **Permalink issues** — WordPress permalinks need to be refreshed

## Server Error Mapping[​](#server-error-mapping "Direct link to Server Error Mapping")

This error code is triggered when the server returns:

| Server Code     | Source              |
| --------------- | ------------------- |
| `rest_no_route` | WordPress REST API  |
| HTTP 404        | Any server response |

## How to Fix[​](#how-to-fix "Direct link to How to Fix")

### 1. Check if the Resource Exists[​](#1-check-if-the-resource-exists "Direct link to 1. Check if the Resource Exists")

Verify the resource still exists on your WooCommerce site:

* Log into WordPress admin
* Navigate to the relevant section (Products, Orders, Customers)
* Search for the item by ID or name

### 2. Refresh Local Data[​](#2-refresh-local-data "Direct link to 2. Refresh Local Data")

If the resource was deleted server-side:

1. Open the POS settings
2. Navigate to the relevant data section
3. Trigger a sync/refresh to update local data
4. The deleted item should be removed locally

### 3. Check WordPress Permalinks[​](#3-check-wordpress-permalinks "Direct link to 3. Check WordPress Permalinks")

If multiple resources are not found:

1. Go to **Settings → Permalinks** in WordPress admin
2. Click **Save Changes** (even without making changes)
3. This refreshes the permalink structure

### 4. Verify API Routes[​](#4-verify-api-routes "Direct link to 4. Verify API Routes")

Test the REST API directly:

```
https://yoursite.com/wp-json/wc/v3/products
```

If this returns a 404, there may be a server configuration issue.

### 5. Check for Plugin Conflicts[​](#5-check-for-plugin-conflicts "Direct link to 5. Check for Plugin Conflicts")

If REST API routes are missing:

1. Ensure WooCommerce is active
2. Ensure WCPOS plugin is active
3. Disable other plugins temporarily to test
