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.

</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.

By default, WooCommerce does not notify your customers when you update a downloadable file or digital product. The Digital Product Update Notifier for WooCommerce solves this by letting you safely queue and broadcast update emails to past buyers with a single click.
Whether you have 10 past buyers or 10,000, this plugin is built for performance. Instead of crashing your server by sending emails sequentially on page save, it uses WooCommerce’s built-in Action Scheduler to process emails efficiently in the background.
<h4>Key Features</h4>
<ul>
<li>Safe Background Processing: Uses Action Scheduler to queue emails, preventing server timeouts and crashes on large stores.</li>
<li>Native WooCommerce Emails: Emails are sent using your store’s global WooCommerce sender details and inherit your native store styling (header, logo, footer).</li>
<li>Customizable Templates: Edit the email subject, heading, and body content directly from the WordPress admin area.</li>
<li>Dynamic Tags: Personalize emails using <code>{product_name}</code> and <code>{account_url}</code> variables.</li>
<li>Test Email Tool: Send a preview email to yourself before blasting your customer list.</li>
<li>Secure Broadcast Logs: Keep track of queue initializations right from your dashboard.</li>
</ul>
<h4>How to use?</h4>
<ol>
<li>Go to WooCommerce > Update Notifier to configure your email template.</li>
<li>When editing any Downloadable WooCommerce product, check the “Notify Past Buyers” box before clicking “Update” to trigger the broadcast.</li>
</ol>
