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.

Common Pitfalls & Troubleshooting
🚫 Double Confirmation (Error 1198)
Each transactionId can only be confirmed once.
- If users refresh the success page, your server might try to confirm again.
- Solution: Check your local database order status before calling
$client->confirm(). If it's already "PAID", skip the API call.
💰 Amount Mismatch (Error 1106)
The amount passed to confirm() must match the amount requested exactly.
- Tip: Do not trust the amount in the URL query string (if any). Always retrieve the amount from your own database using the
orderId.
⏱️ Transaction Expiration
The paymentUrl and transactionId have an expiration time (usually 20 minutes). If the user takes too long, the confirm call will fail.
- Store the expiration time and show a countdown to the user.
- Handle the expiration error gracefully and allow the user to restart the payment.
