weclapp Invoice Sync for OpenCart — weclapp invoices from orders

weclapp Invoice Sync sends OpenCart orders to weclapp: the customer, the articles, a sales order and an invoice with VAT, and the invoice PDF on the order page. In Pro an invoice is issued on a status, a refund creates a credit note and the PDF is e-mailed to the buyer. The weclapp integrations page names Shopify, Shopware, WooCommerce, PrestaShop and Magento; OpenCart is not there.

What the free version does

A panel on the order page: the Create invoice button finds or creates the customer (for a company with the VAT ID from the checkout field), creates the articles, the sales order and the invoice and fetches the number and the PDF. A second click does not create a second invoice. A weclapp outage or an answer lost after the write gives no duplicate: the entry stays in a queue and retries by itself.

What Pro adds

An invoice on the chosen order status, a credit note on the refund status (once) and the invoice PDF by e-mail to the buyer. The invoice in weclapp is created with the status NEW and the owner books it (see below).

How it works, step by step

1. Get your weclapp credentials.
2. Enter them in the module and press the test button.
3. Place one test order.
4. Switch the automation on (Pro) when you are sure.

Under the hood

• The token is encrypted and never shown in the settings.
• A weclapp outage puts the entry into a queue with a retry.
• Languages: English, German.

How to install

1. Extensions → Installer: upload the zip.
2. Extensions → Modules: install and open the module.
3. Module settings: your weclapp subdomain and API token; the Save and check the connection button.
4. Try one test order.

OpenCart 4.0.2 or newer is required. Do not rename the archive.
