Woocommerce PayBox Payment Gateway


Payment gateway using Paybox System.

Evolution of existing WC Paybox Gateway by Open boutique to be compatible with WooCommerce 2.4.5 and up…

Give your WooCommerce customers the possibility to pay with Paybox, and all banks using Paybox services like French bank E-Transactions Crédit Agricole.

Can be used with both CGI and HMAC modes.
Easy to use and preconfigured with preprod + HMAC settings (send test payments to the Paybox preprod url :

This plugin was coded to fix some errors after upgrading WC 2.4.5 when user clicks on „Place order“ button on checkout page.

Errors encountered when using the old version of the plugin :

  • Chrome: „SyntaxError: Unexpected token < „
  • Firefox: „SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data“
  • IE: „SyntaxError: Invalid character“

If you have got such an error after clicking on „place order“ button, juste remove the old Paybox gateway and install this one 😉


  1. Download the appropritate executable at
    Please note that Plug-in uses the CGI as a regular executable, not through a browser

  2. Upload to the /wp-content/plugins/ directory

  3. Activate the plugin through the ‘Plugins’ menu in WordPress
  4. copy Paybox CGI (downloaded at step 0) to a directory visible by Apache on your server
  5. Be careful to setup permissions for this file (readable, executable by Apache)
  6. Change parameters in the Admin dedicated screen (testing Paybox platform by default)
  7. Create paybox landing pages using the dedicated button


I use old WC Paybox Gateway and I have errors like SyntaxError: Unexpected token < on checkout page after upgrading WooCommerce 2.4.5

Install this plugin and all is going to be fine 😉

Should I use CGI or HMAC mode ?

The plugin can use both modes, however we recommand to use HMAC (easiest to configure)
