Joanna, I see that the Tpay integration itself works, but the problem concerns renewals and webhooks between the App and Tpay. I can analyze the flow of recurring BLIK payments, check the aliases, subscription logic, and improve the handling of callbacks so that the recharges are processed correctly. I have 7 years of experience in mobile and web applications, so I will quickly identify the source of the error. I would be happy to discuss the details.

Hello. I can check the Tpay recurring BLIK flow and fix the webhook/subscription part if Base44 allows the needed server/webhook logic.
I would start from one full cycle: first payment and alias registration, saved subscription state, renewal call, Tpay notification back to the app, and app status update. Usually the issue is in alias saving, wrong renewal payload/endpoint, webhook verification, or the app not confirming the callback correctly.
I need access to Base44 config, Tpay merchant settings/logs and one failed renewal example. If the platform has a hard limitation, I will tell it directly after the first check.

Hello. I can switch to Polish if you prefer, but to be precise on a payment issue I will keep this in English. I read the brief: the Tpay integration is mostly done in your Base44 app, single BLIK payments go through and are registered with the bank as recurring, but the automatic renewal fails when the subscription ends, and the problem sits on the webhook line between the app and Tpay in both directions.
Recurring BLIK with Tpay works through a saved alias from the first transaction, and the renewal is a separate server-to-server charge that uses that alias rather than a new BLIK confirmation. The usual failure points are exactly there: the alias not being stored or sent correctly on the follow-up charge, the recurring transaction being initiated with the wrong flag or endpoint, or the Tpay notification webhook not being received and confirmed by the app, so the renewal never completes or is not recorded.
My approach would be to trace one full cycle end to end: the first payment and alias registration, then the renewal call and the notification webhook both ways, find where the alias or the confirmation breaks, and fix the renewal charge and the webhook handling so the subscription renews on its own. I work with payment gateway integrations, webhooks and APIs regularly.
To scope it precisely: does Base44 let you add custom backend code or webhook endpoints, or is the integration limited to what the platform exposes, and can you share the Tpay merchant configuration and the logs from a failed renewal? Ready to start by reproducing one renewal cycle and isolating the break.

I understand the problem with renewing the BLIK subscription in the Strefa Przemienieni.pl application. The first payment goes through and registers the alias in Tpay, but subsequent attempts to collect funds fail due to improper handling of webhooks. Base44.app has a specific structure, but the key lies in the correct registration of the alias token sent in notifications.
I have extensive experience in integrating the Tpay payment gateway and subscription systems. I will implement the correct logic for the return webhook, which, after a successful transaction, saves the user's alias and then triggers the next charge. An example outline of my approach to handling the notification looks as follows:
if ($payment['status'] === 'correct' && isset($payment['cli_auth'])) {
$this->saveBlikAlias($userId, $payment['cli_auth']);
$this->scheduleNextBilling($userId, $payment['cli_auth']);
}
I need access to the Tpay account and the Base44.app panel to verify the current configuration of webhooks and logs.

Hello. I have experience integrating payment systems and working with webhook logic for subscriptions. I can analyze your App ↔ Tpay chain, check the processing of BLIK alias/recurring payments, and fix the subscription renewal mechanism so that the charges occur automatically through webhooks and the status in the application is updated correctly. I will also check where the event chain breaks during the retry and how to stabilize it.

Hello.
I work with web development, API integrations, automation, and backend logic. I carefully read the description of the problem.
From your description, it seems that the registration of the recurring payment is successful, but the issue arises at the stage of subsequent charges and processing the chain of webhooks between the application and PayU.
What I can do:
• check the current implementation of the integration;
• analyze the chain App → PayU → App;
• check the webhooks, request signatures, and status handling;
• find the reason why the recurring charges are not being executed;
• suggest and implement a fix;
• assist with testing subscription renewal scenarios.
I have experience working with APIs, handling external requests, databases, and debugging business logic in applications. If the problem is indeed localized in one area of the integration, it is likely that it can be resolved without a complete overhaul of the system.
I am ready to start with analyzing the current implementation and the logs of the webhooks.

Hello! The task is completely clear to me, and the budget and deadlines are fully acceptable. I have successful experience working with Notion table automation and workflow setup.
Instead of manual copying, which takes a lot of time, I propose to set up an automatic script (Workflow) based on the n8n platform. The bot will independently input information into your Notion tables, check statuses, and instantly update lists. This will completely eliminate human errors and delays throughout all 4 weeks.
I deploy all processes on my own secure VPS server, so your data will be completely safe. I am ready to discuss the details, look at the structure of the lists, and promptly start working.
