OpenCart & PrestaShop - Filecheck

OpenCart and PrestaShop follow the same pattern as WooCommerce. All platforms share identical front-end output: a mount point, a hidden field for the job id, and Filecheck.mount.

<div id="fc-inline"></div>
<input type="hidden" name="fc_job_id" id="fc-job-id" value="">
<script src="https://cdn.filecheck.io/element/{pk}/filecheck.js" async></script>
<script>
(function () {
  var started = Date.now();
  (function tick() {
    if (window.Filecheck && window.Filecheck.mount) {
      var el = window.Filecheck.mount({
        publishableKey: '{pk}',
        workflowId:     '{workflowId}',
        presentation:   '{presentation}',
        connectorId:    '{connectorId}' || undefined,
      });
      if (el) el.on('status', function (e) {
        document.getElementById('fc-job-id').value = e.jobId || '';
      });
      return;
    }
    if (Date.now() - started < 10000) setTimeout(tick, 50);
  })();
})();
</script>

Filecheck.mount handles mounting into #fc-inline, cart-button gating, dialog creation, and the proof gallery. The only platform-specific code is the status to hidden fc_job_id write for server-side verification.

Per-platform differences

Module admin: store publishable key, secret key, agentId, default workflowId, presentation, and per-product workflowId / connectorId overrides.
Add-to-cart / checkout: validate that jobId was submitted; persist it as an order attribute.
Post-purchase: use the secret key server-side to fetch output and attach it to the order.
