<h3>Product Sync</h3>
<p>Every sync runs two phases on the same triggers:</p>
<ul>
<li><strong>Pull (Fungies to WooCommerce)</strong> — <code>GET /v0/offers/list</code>, then for each offer create or update a matching WooCommerce product (name, description, image, price, currency).</li>
<li><strong>Push (WooCommerce to Fungies)</strong> — for each published WooCommerce product, build a OneTimePayment product and offer body, then either <code>PATCH</code> an existing one or <code>POST</code> a new one.</li>
</ul>
<h4>Triggers</h4>
<ul>
<li><strong>Sync Now button</strong> in WooCommerce <span aria-hidden="true" class="wp-exclude-emoji">→</span> Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Fungies</li>
<li><strong>WP-Cron</strong>, hourly</li>
<li><strong><code>woocommerce_update_product</code> / <code>woocommerce_new_product</code></strong> hooks (push only, debounced 5 seconds)</li>
</ul>
<h4>Loop and duplicate prevention</h4>
<ul>
<li><code>_fungies_offer_id</code> on a WooCommerce product marks it as Fungies-originated <span aria-hidden="true" class="wp-exclude-emoji">→</span> skipped during push.</li>
<li><code>_fungies_pushed_offer_id</code> on a WooCommerce product marks it as already-pushed <span aria-hidden="true" class="wp-exclude-emoji">→</span> skipped during pull.</li>
<li>A runtime <code>is_pulling</code> flag prevents WooCommerce update hooks from firing while the pull writes to the database.</li>
<li>A 5-second per-product transient lock debounces rapid-fire saves.</li>
<li>If a <code>PATCH</code> returns 404 “Product not found” (e.g. after switching from staging to production keys), stale IDs are cleared and the product is recreated in the current workspace.</li>
</ul>
<h4>Currency handling</h4>
<p>The plugin auto-detects the Fungies workspace currency. If your WooCommerce currency does not match, the push phase errors out with a clear message — products are never pushed at the wrong currency.</p>
<h4>Meta keys reference</h4>
<ul>
<li><code>_fungies_offer_id</code> — Fungies offer ID this WooCommerce product mirrors (set on pull).</li>
<li><code>_fungies_currency</code> — currency the offer was priced in (set on pull).</li>
<li><code>_fungies_checkout_url</code> — pre-built single-offer hosted checkout URL (set on pull).</li>
<li><code>_fungies_pushed_product_id</code> — Fungies product ID for a WC-originated product (set on push).</li>
<li><code>_fungies_pushed_offer_id</code> — Fungies offer ID for a WC-originated product (set on push).</li>
<li><code>_fungies_pushed_at</code> — timestamp of last successful push.</li>
</ul>
<h3>Checkout URL Generation</h3>
<p>When a customer clicks <strong>Place Order</strong>, the plugin produces a different Fungies hosted checkout URL depending on how many distinct offers are in the cart.</p>
<h4>Step 1 — Collect offer IDs</h4>
<p>For each cart line item, the builder resolves a Fungies offer ID by checking, in order:</p>
<ol>
<li><code>_fungies_offer_id</code> (product was pulled <strong>from</strong> Fungies).</li>
<li><code>_fungies_pushed_offer_id</code> (product was pushed <strong>to</strong> Fungies from WooCommerce).</li>
</ol>
<p>Each unit (quantity) becomes one entry in the resulting offer-IDs array. Items without either meta key are logged and skipped.</p>
<h4>Step 2 — Build the URL</h4>
<p><strong>Single offer</strong> (1 distinct offer ID, quantity 1) — no API call is needed. The plugin redirects directly to:</p>
<pre><code><store_url>/checkout/<offer_id>?fngs-customer-email=...&fngs-customer-country=...
</code></pre>
<p><strong>Multiple offers</strong> (2 or more, or quantity > 1) — the plugin calls <code>POST /v0/elements/checkout/create</code> with all collected offer IDs, then redirects to:</p>
<pre><code><store_url>/checkout-element/<element_id>?fngs-customer-email=...&fngs-customer-country=...
</code></pre>
<p>The element ID is also stored on the WooCommerce order as <code>_fungies_checkout_element_id</code> for traceability. When the customer lands on the hosted checkout, Fungies promotes the element into a checkout session and the URL becomes <code>…/checkout-element/<element_id>/checkout/<session_id></code> — every cart product is visible in the order summary.</p>
<h4>Why two URL shapes?</h4>
<p>The single-offer URL is stateless — no API call, no rate-limit cost, no extra latency. The multi-offer flow has to use the Checkout Element endpoint because Fungies’ single-offer URL only carries one offer ID. Before v2.1.6, multi-item carts would silently lose every line item except the first.</p>
