API05001: WooCommerce API Disabled

What This Means​

The WooCommerce REST API is disabled on your site. WCPOS requires the REST API to communicate with WooCommerce and access store data.

Common Causes​

  • WooCommerce setting — The REST API was intentionally disabled
  • Security plugin — A security plugin is blocking API access
  • Hosting restriction — Your host has disabled REST API access
  • Permalink issues — Permalinks not configured for REST API

How to Fix​

1. Enable WooCommerce REST API​

In WordPress Admin:

  1. Go to WooCommerce → Settings → Advanced → REST API
  2. Ensure the REST API is enabled
  3. Verify API keys are created

2. Check WordPress REST API​

The WooCommerce API depends on WordPress REST API:

  1. Visit https://yoursite.com/wp-json/ in your browser
  2. Should return JSON data
  3. If not, see API05004

3. Check Security Plugins​

Common security plugins that may block the API:

  • Wordfence — Check firewall settings
  • iThemes Security — Check REST API settings
  • All In One WP Security — Review firewall rules

Whitelist REST API endpoints or the POS application.

4. Check .htaccess​

Look for rules blocking API access:

# Remove or modify rules blocking /wp-json/
# Ensure mod_rewrite is enabled

Sometimes permalink settings need refreshing:

  1. Go to Settings → Permalinks
  2. Click "Save Changes" (even without making changes)
  3. This regenerates rewrite rules
