FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package module-payzum
Payzum for Akaunting
Accept crypto and stablecoin payments (USDC, USDT and more, multi-chain) in Akaunting through Payzum — non-custodial: funds settle directly to your own wallet, Payzum never takes custody.
The app is built on Akaunting's own Omnipay layer (app/Traits/Omnipay.php;
the core already ships league/omnipay) plus the published
payzum/omnipay-payzum
driver, and follows the structure of the official
PayPal Standard app.
How it works
- The customer opens an invoice in the client portal (or via the signed invoice link), picks Payzum and clicks Confirm.
- The app creates a Payzum hosted-checkout invoice and redirects the buyer to it. No card or wallet data ever touches your server.
- Crypto confirmation is asynchronous, so the invoice is marked as paid only from Payzum's server-to-server payment notification (IPN), whose HMAC-SHA-512 signature is verified over the raw request bytes (with a replay window) before any field is read. The browser return just shows a "payment is being confirmed" notice.
- The IPN endpoint itself lives on a Laravel signed URL, and the order id, amount, and currency of every notification are checked against the invoice. Redelivered notifications are idempotent — an invoice is never credited twice.
Install
From the release zip (recommended). Download
payzum-akaunting-0.2.0.zip and
unzip it inside modules/ of an Akaunting ≥ 3.0 install — the archive already contains the
Payzum/ folder.
From a clone. Copy this repository's contents to modules/Payzum. Either way the vendor/
directory is included, so there is no composer step. Then enable Payzum from the admin panel and
open its settings:
| Setting | Meaning |
|---|---|
| API Key | From your Payzum merchant dashboard |
| Webhook Secret | Used to verify payment notifications |
| Mode | Live, or Sandbox for the Payzum staging environment |
| Pay Currency | Optional: pin the crypto asset (e.g. usdc); empty lets the buyer choose |
| Account | The Akaunting account payments are recorded into |
| Show to Customer | Whether portal customers see the method |
Tests
The suite runs inside the Akaunting test harness (it covers the signed-IPN flow end to end — forged signatures, order/amount mismatches, pending states, and redelivery idempotency):
