seafishingcharters

Install on your WordPress site, set your charter slug under Settings → SFC Calendar, then add:
<pre><code>[sea_fishing_charters]
</code></pre>
The plugin loads availability from the Sea Fishing Charters API (server-side, cached 10 minutes) and displays a month calendar with colour-coded dates.
<h3>External services</h3>
This plugin connects to the Sea Fishing Charters API to load public charter availability for the calendar shortcode.
When a page with the calendar is viewed, your WordPress site sends a server-side request to <code>https://api.seafishingcharters.com/charters/{slug}/availability</code> with your configured charter slug and a date range (from the first day of the current month through twelve months ahead). No visitor personal data is sent. Responses are cached on your server for 10 minutes.
