Problem with online payment liqpay

Budget: 5000 UAH Deadline: 2 days

Hello. I have extensive experience with OpenCart. I am ready to analyze the problem and fix it.

Good day!

I have dealt with payment system integrations and OpenCart, so I understand the issue at hand.

Before changing hosting or purchasing a new IP, I would conduct a full diagnosis:
• check the callback URL from LiqPay;
• analyze the logs of OpenCart, PHP, and the web server;
• check the availability of the LiqPay API from the server;
• check the SSL certificate and HTTPS settings;
• test server-to-server requests;
• check the module settings and order statuses.

Indeed, the problem may be related to the IP or network restrictions, but in practice, the cause is often incorrect handling of callback requests, server settings, or AWS network rules. Therefore, it is worth first obtaining confirmation through logs and tests, and only then making a decision regarding changing the server or IP.

I am ready to connect, conduct an audit, and determine the exact cause to avoid spending money on unnecessary infrastructure changes.

To start, it would be helpful to see:
• the version of OpenCart;
• the link to the website;
• access to error logs or examples of failed payments. Expand

Hello! I have done LiqPay integrations on OpenCart, and I have encountered this situation — the payment went through, but the order remains "unsuccessful" — I have caught this several times. Most often, the reason is not an IP ban, but that LiqPay sends the status to server_url (callback), and the site either does not accept it or the signature does not match — then the order does not close. The first thing I will do is check if the callback actually reaches the server logs and if the signature is valid; we will check the AWS ban version second. I am ready to diagnose it in a day. Will you provide log access to the server?

Hello, Serhiy! I have done LiqPay integrations and have seen this behavior: the payment goes through, but the order remains "unsuccessful." Almost always, this is about the callback — LiqPay sends the result to the server_url, and if the server does not accept it or the signature does not match, the order does not close. The developer's version about the IP ban on AWS is possible, but this is just one of the scenarios, and it needs to be confirmed, not taken at face value.

Here’s what I would do in order:
1. Check access to the LiqPay API from the server (curl) — if the request does not go from there, then yes, the issue is with the IP or firewall, and I can tell you for sure if it’s a ban or not.
2. Look in the logs to see if the callback from LiqPay is actually coming to the server_url and if the signature is calculated correctly.
3. Compare the status in the LiqPay cabinet with what the module sets in the order.

This will make it clear where exactly the issue lies: either it’s a setting/code adjustment, or I confirm that the IP needs to be changed, and then you are not paying the hosting randomly.

Please clarify two points to avoid guessing: is there SSH/FTP access to the server, and does the LiqPay cabinet show this payment as successful? I am ready to show in correspondence how I check. Approximately one to two days for diagnostics and fixes.

or you can create a redirector, but then you will need another hosting and some domain, maybe do it on a subdomain somehow, and write a script and a page, and go through moderation in liqpay again.

Hello! The problem is known, the module developer is right in the direction, but the situation can be resolved without a radical "guesswork" move.

Hello.

I have worked with OpenCart and LiqPay. First, it is important to understand why the site is not receiving payment confirmations, and only then draw conclusions about AWS or changing hosting.

I can quickly conduct diagnostics and suggest a solution.

Budget: 1000 UAH Deadline: 1 day

Good day, Serhiy! The problem is understood — LiqPay is not receiving payment confirmation, or your server is not processing the callback. The version about the AWS IP ban is possible, but not the only one — more often the reason lies in incorrect processing of server_url or an invalid signature. Here’s what I will do: I will check the server logs for incoming requests from LiqPay, check curl access to the LiqPay API directly from your server (to confirm or refute the IP ban), verify the signature in the callback handler, and check the server_url settings in the module. If the IP is blocked — I will suggest the quickest solution (dedicated IP or proxy). If the problem is in the callback — I will fix the code. Please provide access to the hosting panel and OpenCart admin — we will resolve it within a day.

Greetings.

The issue should be checked not at the module replacement level, but at the full LiqPay chain level: the website, callback, order status in OpenCart. If an order is not created or goes into an unsuccessful status after successful payment, it is necessary to separately check the availability of the LiqPay API from the server, the webhook/callback URL, SSL, server logs, LiqPay responses, and status handling in the module.

The version with IP blocking is possible, but it needs to be confirmed technically: make requests to the LiqPay API directly from the server, check cURL/SSL, DNS, firewall, outbound connections, and compare the result with a request from another IP. Only after this does it make sense to make a decision regarding a dedicated IP, changing the server, or moving the site to another hosting.

The optimal order of work: diagnosis of the current module and OpenCart logs, checking the callback handler, test payments, checking network access to the LiqPay API, after which either configuration/response handling corrections can be made, or a technical recommendation regarding IP/hosting change with justification.

The estimated time for initial diagnosis is 2–4 hours. If the cause is confirmed at the module, callback, or server settings level, corrections can usually be made within one working day. The preliminary budget is $50–100, excluding possible costs for a dedicated IP, new server, or site migration.

To start, access to the OpenCart admin panel, FTP/SSH or hosting panel, LiqPay settings, and the ability to perform a test payment in a controlled mode is required. Expand

Hello! I have encountered similar API integration issues — I will diagnose the connection between LiqPay and OpenCart, check the IP ban on AWS, and set up the correct return of order data within 1 day (1,500 UAH). I hope for cooperation!

Budget: 1000 UAH Deadline: 1 day

Good day, Serhiy!

The problem is understood — LiqPay is not receiving confirmation from your server (callback/webhook).

What I will do:
- Check the nginx/Apache logs for incoming requests from LiqPay
- Check the server_url in the module settings
- If the IP is blocked — resolve it through whitelisting or changing the IP without migrating the hosting
- If the problem is with the firewall — open access for the IP ranges of LiqPay

Diagnosis + fix: 1-2 hours.
Cost: 1000 UAH Expand

Hello. The task is completely clear. The issue of notifications disappearing from payment systems (when the payment has gone through, but the site is unaware of it) is a classic failure in processing callback requests.

The previous developer's version about blocking makes sense, but the suggestion to immediately move the entire site to another hosting is too radical, expensive, and a major intervention that can be avoided.

I propose to solve the problem much faster and without stress for the site's functionality:

1. Targeted diagnostics: I will check the request logs and network availability between your server and the payment gateway. We will clearly see where the connection is breaking.
2. Security system check: often such requests are blocked by internal security screens or filters of the site itself. If the problem lies there, I will set up the correct access rules.
3. Local solution with IP: if it turns out that the current IP address is indeed restricted due to "neighbors" on the server, we can resolve this in 15 minutes directly in your current hosting panel without any moves or migrations of the site.

I have extensive experience with OpenCart 3 and LiqPay integration, I will find the real cause and restore the automatic status change of orders.

Cost of diagnostics and correction: 1000 UAH.
Deadline: I will complete it within a few hours after receiving access.

For analysis, I will need access to the site admin panel and hosting panel. I am ready to discuss the details of the technical check with you in private messages. I look forward to your feedback! Expand

Hello. I know both OpenCart and LiqPay very well. The response from the previous developer is questionable. Feel free to contact me, I will fix it.

Budget: 1000 UAH Deadline: 2 days

Hello, you can temporarily purchase another IP and test the module's functionality. It's not difficult and can be done relatively quickly.

You need to contact the hosting support and order such a service from them. After that, set up the website on this IP and check its operation.

I would be happy to help.

Integration with LiqPay on OpenCart 3 is well known, including the nuances with callback notifications when the payment goes through but the order does not update. Most likely, the problem lies in the processing of server_url or the response signature from LiqPay is not verified correctly, which is why the order status does not change. Please clarify: in the OpenCart logs or on the LiqPay side, is it visible that the callback is reaching the site at all, or is it not arriving at all?

Budget: 1000 UAH Deadline: 2 days

Good day! We have experience in setting up payment system integrations on OpenCart. The problem usually lies in the incorrect processing of callback requests or conflicts in order statuses. We will conduct a diagnosis of the server logs, check the correctness of API key transmission, and configure the proper return of status after a successful transaction. We will implement this through the payment controller check and system hook settings.
