Jurnal by Mekari for OpenCart — invoices, customers and products from orders

Jurnal by Mekari for OpenCart creates an invoice in Jurnal (Mekari’s Indonesian accounting) from an OpenCart order: the customer and the products are created once and reused. The order page gets a box with the invoice number and buttons, and there is a document list under Sales → Jurnal invoices. The Mekari Jurnal integrations page names neither OpenCart nor WooCommerce (2 November 2026); a third-party plugin for WooCommerce exists on GitHub, and we found no connector for OpenCart.

This module has never run against the real Jurnal. We had no Jurnal company and no Mekari Developer application, so nothing was ever sent to Jurnal.

What the free version does

“Create the invoice in Jurnal” on an order creates the customer, the products (lines and shipping) and the invoice; the invoice total equals the order total (155,000 Rp in the check). The same buyer and the same products are not created a second time; a buyer with the same name but another e-mail gets a record of their own. If Jurnal does not answer, the document is marked “Stopped” with a “Send again” button and a note to look in Jurnal first so as not to make a second invoice. The invoice on the page has a number and a link. The module works only when the shop’s default currency is IDR, otherwise it shows a plain warning.

What Pro adds

An invoice at an order status, a payment recorded at a paid status into the cash account you name, a return of the whole order, deleting the invoice in Jurnal, and an e-mail to the buyer with the invoice link.

How it works, step by step

1. In Mekari Developer create an application and link it to your Jurnal company; copy the Client ID and Client Secret.
2. Install the module, enter them in its settings and press “Save and check the connection”.
3. Make sure the shop currency is IDR.
4. Open an order and press “Create the invoice in Jurnal”.

Under the hood

• HMAC-SHA256 signature as Mekari describes; the secret is never printed back.
• A failed invoice POST without an answer is never resent automatically: the owner checks Jurnal and presses “Send again”.
• Languages: English, Bahasa Indonesia.
