Requirements

Before installing Pingen Post, make sure your environment meets the following requirements.

Blesta

• Blesta 5.x or 6.x

PHP

• PHP 8.2 or newer
• ionCube Loader 13 or newer
• memory_limit of at least 256M

Pingen.com account

• A pingen.com account — free to create. You need it to obtain the API credentials the plugin uses to submit letters. See Pingen Account Configuration for the walkthrough.

Try staging first

Pingen offers a separate staging environment where letters are validated but never physically dispatched — and never charged. Create staging credentials alongside your production ones so you can test end-to-end at no cost.

PHP extensions

Pingen Post requires the following PHP extensions:

• curl
• json
• mbstring

On most systems these are already active. If any are missing, install them as shown below.

Installing missing extensions

Debian / Ubuntu

sudo apt install php-curl php-json php-mbstring

RHEL / Alma / Rocky

sudo yum install php-curl php-json php-mbstring

After installing, restart your web server (or PHP-FPM) for the changes to take effect.

Next steps

Once your environment is ready, continue to Installation.
