3rd party extension / USPS Shipping for VirtueMart 4...
Last post by Jumbo! - June 24, 2026, 00:57:01 AMReal-time USPS shipping rates in VirtueMart, on the new USPS REST API
The old USPS Web Tools XML API was retired in January 2026. That change broke a lot of older USPS shipping plugins, and many stores suddenly stopped showing live postage at checkout.
VP USPS Shipping is built on the new USPS REST API, the official replacement that uses OAuth 2.0 and JSON. Your store keeps quoting accurate USPS rates, fetched live at checkout from the real cart weight, the package dimensions and the customer's destination.
You can use retail or commercial base rates, and commercial rates do not need a USPS account number. Built-in rate caching keeps you within the USPS limit of 60 requests per hour, and you can point the plugin at the production or the staging environment while you test.
Domestic services
International services
A FEW THINGS THAT SET IT APART
One thing to be clear about. Rates come back in US Dollars with no currency conversion, and the plugin is built for stores that ship from a US address, since USPS only collects packages inside the US.
No hacks, no manual file edits. Install the plugin with the normal Joomla Extensions Installer, enter your USPS Client ID and Secret, enable it, and you are ready to go.
System Requirement: VirtueMart 3.8+, 4.0, 4.2, 4.4 or 4.6 | Joomla 3, 4 or 5 | PHP 7.1+ (PHP 8.1+ recommended for Joomla 5) | cURL extension enabled

Domestic services
- Priority Mail and Priority Mail Express
- USPS Ground Advantage
- First-Class Package Service
- Media Mail and Library Mail
- Small, Medium and Large Flat Rate Boxes
- Flat Rate, Legal and Padded Envelopes, for Priority Mail and Priority Mail Express
International services
- Priority Mail International and Priority Mail Express International
- First-Class Package International Service
- Global Express Guaranteed
- International flat rate boxes and envelopes
A FEW THINGS THAT SET IT APART
- Smart Flat Rate. A 3D box-packing algorithm checks that the products physically fit inside a flat rate container before that container is offered, so you never quote a box the order cannot go in.
- Multi-box shipping for heavy orders, with configurable outer box dimensions per method, a cart weight padding option and a machinable toggle.
- Show Cheapest Option Only. Collapse the results to the single lowest-priced method that qualifies when you want a simpler checkout.
- Handling fees as a flat amount, a percentage of the shipping cost, or a percentage of the cart total. Per-method tax rules and logos are supported too.
- Restrictions by destination country, ZIP or postal range, order amount, product category and a blocking category. On VirtueMart 4.6 and later it uses the VirtueMart core restrictions, which also add blocking countries, and it falls back to its own restrictions on older versions.

Last post by sylwekb - June 23, 2026, 12:14:55 PMUnfortunately, there has been no response from the Virtuemart developers so far. There's no news on this matter. If anyone knows of an update, please let me know. This is very important for Virtuemart stores users.

Last post by iWim - June 19, 2026, 15:41:32 PMJ4 is old too.
I recomend to install your webshop locally on WAMPserver or MAMP.
Use Akeeba Backup + Kickstart.
On this testsite, update it to J5 and VM 4.6.8. See if that fixes the issue. (VM4.6.8 uses jquery-ui.min.js?vmver=1.13.2)
When you update on a testsite first you can test changes and you'll get familiar with the update process.

Last post by iWim - June 19, 2026, 15:31:07 PMAs of today, this is the law.
It is mandatory for webshops selling in the EU to clearly display an option for customers to undo a sale.
Shop owners risk fines if they don't comply.
VM needs to implement this yesterday.

Last post by MAD King - June 17, 2026, 14:15:14 PMHello,
does anyone know how to create an purchase event button for Facebook?
I only can point to e.g. "Add to Cart" but I think it actually requires the link for the thank you page.
Anyone who can help?
Thank you.

General Questions / Re: Deprecated: file_exists()
Last post by scottstreet - June 17, 2026, 00:39:22 AMI found this and it fixed the appearance problem: Now an icon does appear, not a correct one, but a placeholder at least and not an error message:
he quick fix in most cases is to use the null coalescing operator to provide a default value as appropriate, so you don't need a long null check around every use. For instance, htmlspecialchars($something) can be replaced with htmlspecialchars($something ?? '')
that worked on line 690 of mediahandler.php in the file: administrator/components/com_virtuemart/helpers/mediahandler.php
