Complete Installation & Configuration Guide for Courier Center Voucher for WooCommerce
In this guide you’ll see, step by step, how to install and configure
Courier Center Voucher for WooCommerce, how to correctly enter the test/live
API credentials, complete the required test scenario and use the plugin daily
directly from WooCommerce orders.
What we are going to configure
Courier Center Voucher for WooCommerce connects your store with Courier Center API/Web Services, so you can issue, print, cancel and track vouchers directly from WooCommerce orders.
1) Before you start
To use the plugin, Courier Center API credentials are required. Typically, Courier Center provides test credentials first for the staging environment and, after the test is successfully completed, provides the live credentials for production.
You will need:
- Username / UserAlias
- Password / CredentialValue
- API Key
2) Installation & activation
Installation works like any other WooCommerce plugin.
.zip file you downloaded after purchase.
3) API connection settings
Open the plugin settings page, for example from VGDev Solutions → Courier Center.
API connection details
In the API Connection Details section, fill in:
- Username / UserAlias
- Password / CredentialValue
- API Key
Save & test connection
- First click Save Settings so the new credentials are stored.
- Then click Test Connection to confirm that communication with Courier Center works correctly.
4) General settings
In the General Settings section, you will find options that affect the daily plugin workflow.
Default weight
The Default weight (kg) field works as a fallback when the order weight cannot be calculated.
- If you leave the field empty, the plugin automatically gets the product weights from WooCommerce and calculates the total order weight.
- If some products do not have weight, set a safe value such as
1, so voucher creation does not fail.
Label / print size
From the Label Size field, you select the default voucher print format, depending on how you print your vouchers.
- A4 / A4 Clean for A4 printing.
- Single PDF / Single Clean for one voucher per PDF.
- Single 100×150 / Clean 100×150 for 100×150 mm label format.
- Single 100×170 / Clean 100×170 for 100×170 mm label format.
Convert to uppercase
If you want recipient details, such as address and other fields, to be sent in uppercase without accents, enable the corresponding option.
Change order status
You can set an automatic order status change when a voucher is created, or keep the setting without change.
5) Test mode
Courier Center usually asks you to confirm that the main parts of the integration work correctly.
- Voucher creation.
