Fungies.io

Fungies for WooCommerce lets you sell digital products through your WooCommerce store while <a href="https://fungies.io" rel="nofollow ugc">Fungies.io</a> handles payments, taxes, and compliance as your Merchant of Record.
You keep full control of your storefront. Fungies takes care of the hard parts — payment processing, tax collection, invoicing, and regulatory compliance — so you can focus on your products.
<h4>How It Works</h4>
<ol>
<li>Connect — Paste your Fungies API keys in WooCommerce → Settings → Fungies</li>
<li>Sync — Your Fungies products are automatically imported into WooCommerce</li>
<li>Sell — Customers browse your store and check out via Fungies hosted checkout</li>
<li>Get Paid — Fungies processes the payment and sends a webhook to complete the WooCommerce order</li>
<li>Stay in Sync — Orders, refunds, and subscriptions are kept up to date automatically</li>
</ol>
<h4>Features</h4>
<ul>
<li>Two-Way Product Sync — Pull OneTimePayment products from Fungies into WooCommerce AND push WooCommerce products to Fungies as OneTimePayment offers (name, description, price, featured image)</li>
<li>Auto-Sync on Product Save — Editing a WooCommerce product automatically updates the matching offer in Fungies</li>
<li>Currency Validation — Detects your Fungies workspace currency and warns if it differs from your WooCommerce store currency</li>
<li>Multi-Item Hosted Checkout — Carts with multiple products create a Fungies Checkout Element so all line items appear on the hosted checkout page</li>
<li>Detailed Sync Panel — Clear summary under “Sync Now” showing pull/push counts and per-product errors</li>
<li>Duplicate Protection — Products pushed from WooCommerce to Fungies will not be re-imported as duplicates on the next pull</li>
<li>Hosted Checkout — Customers are redirected to a secure Fungies checkout page to complete payment, then returned to your WooCommerce thank-you page</li>

<li>Opt-In Debug Logging — Toggle verbose request/response logging in WooCommerce → Status → Logs (source: <code>fungies</code>). Errors and warnings are always logged; verbose dumps are off by default to keep log files small and avoid storing third-party API payloads unless you’re troubleshooting.</li>
<li>Dashboard Widget — See your sync status at a glance from the WordPress dashboard</li>
</ul>

<li>During checkout, customers are redirected to the Fungies hosted checkout page. Their email address and country code are passed as URL parameters.</li>
<li>During webhook processing, Fungies sends order and payment data (order ID, payment status, amounts, subscription details) to your WordPress site.</li>
</ul>
Service endpoints used:
<ul>
<li>Production API: <code>https://api.fungies.io/v0</code></li>

</ul>
<h3>Product Sync</h3>
Every sync runs two phases on the same triggers:
<ul>
<li>Pull (Fungies to WooCommerce) — <code>GET /v0/offers/list</code>, then for each offer create or update a matching WooCommerce product (name, description, image, price, currency).</li>
<li>Push (WooCommerce to Fungies) — 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>Sync Now button in WooCommerce → Settings → Fungies</li>
<li>WP-Cron, hourly</li>
<li><code>woocommerce_update_product</code> / <code>woocommerce_new_product</code> 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 → skipped during push.</li>
<li><code>_fungies_pushed_offer_id</code> on a WooCommerce product marks it as already-pushed → 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>
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.
<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>
When a customer clicks Place Order, the plugin produces a different Fungies hosted checkout URL depending on how many distinct offers are in the cart.
<h4>Step 1 — Collect offer IDs</h4>
For each cart line item, the builder resolves a Fungies offer ID by checking, in order:
<ol>
<li><code>_fungies_offer_id</code> (product was pulled from Fungies).</li>
<li><code>_fungies_pushed_offer_id</code> (product was pushed to Fungies from WooCommerce).</li>
</ol>
Each unit (quantity) becomes one entry in the resulting offer-IDs array. Items without either meta key are logged and skipped.
<h4>Step 2 — Build the URL</h4>
Single offer (1 distinct offer ID, quantity 1) — no API call is needed. The plugin redirects directly to:
<pre><code><store_url>/checkout/<offer_id>?fngs-customer-email=...&fngs-customer-country=...
</code></pre>
Multiple offers (2 or more, or quantity > 1) — the plugin calls <code>POST /v0/elements/checkout/create</code> with all collected offer IDs, then redirects to:
<pre><code><store_url>/checkout-element/<element_id>?fngs-customer-email=...&fngs-customer-country=...
</code></pre>
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.
<h4>Why two URL shapes?</h4>
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.
