Frequently Asked Questions

Common questions about Invoice-api.xhub for WooCommerce

No. WooCommerce 8.0 or later is required. The plugin fails closed and shows an admin notice when WooCommerce is missing.

Yes. The plugin declares custom_order_tables compatibility. Order data is read through the WC_Order API, not directly from wp_posts.

In /wp-content/uploads/invoice-api-xhub/<order-id>/<filename>. The plugin writes a .htaccess file with Deny from all to block direct URL access (Apache). On Nginx, add location ~ /uploads/invoice-api-xhub/ { deny all; } to your server config — invoices contain buyer addresses and must not be web-accessible. Order meta stores only the relative path. Older installs of the plugin (≤ v0.x) stored the base64 payload directly on the order; the read path supports both for backward compatibility.

Yes. Open the order, find the Invoice-api.xhub meta box on the right, click "Re-generate invoice".

No. The plugin produces the XRechnung XML and stores it on the order. You upload it to the federal/state platform yourself, or pass it to your accounting software which does.

Order meta _invoice_api_xhub_leitweg_id or _invoice_api_xhub_buyer_reference if set, then the global Leitweg-ID from settings, finally the WooCommerce order number as buyer reference.

The invoice-api.xhub.io API returns the generated XML or PDF file as a base64-encoded string in the JSON response (this is the standard pattern for delivering binary data over JSON). The plugin decodes that string with base64_decode() so it can be served to the merchant as a download or attached to the customer email. The function is not used to evaluate or execute any data — only to decode HTTP-response payload. The decoded content is treated as opaque file bytes and never passed to eval, assert, create_function, or similar.

Out of the box, the default format INV-{order_number} reuses the WooCommerce order number, which is not guaranteed to be gap-free across the entire system (deleted orders, other plugins reserving IDs). For German tax compliance use a format with the {seq} token, e.g. 2026-{seq:0000}. The plugin maintains a separate sequential counter that is uniquely incremented for every generated invoice, with optional yearly or monthly reset.

Yes. By default the plugin uses the standard template provided by invoice-api.xhub.io. To use your own: Log in to https://console.invoice-api.xhub.io/pdf/templates Create a new template (or copy one of the starter templates) — adjust layout, logo, colors, header/footer blocks Save and copy the Template-ID (UUID format, e.g. 550e8400-e29b-41d4-a716-446655440000) In WordPress: WooCommerce → Settings → Integration → Invoice-api.xhub → "Default Template-ID" — paste it, save From now on every generated invoice uses your template. Templates are format-specific — a template designed for XRechnung will not work for ZUGFeRD or PDF. To use a different template for a specific order (e.g. B2C vs. B2B layouts), set the order's custom field _invoice_api_xhub_template_id before the generate fires. Per-order override beats the global default.
