We kindly inform you, that due to urgent technical work, our API production environment will be unavailable today on the 30th of June 2025 between 2:30 PM and 2:45 PM.
The Bank does not provide immediately available alternative options for payment service providers using the dedicated interface during its unavailability.
Migration of businesses customers to the new service system
We have started the process of transferring businesses customers service from the current BusinessPro online banking system to the new Alior Business system, which is gradually include subsequent groups of customers.
After transferring the service to the new system, consents to access accounts information service (AIS service) which were authorized by customers in BusinessPro banking, will no longer be supported. This is due to the fact each time the consent is authorized in the context of a specific online banking system through which the customer has online access to his accounts. In order to continue using the AIS service, customers will have to initiate the consent refresh process or grant a new one consent in your systems to provide the AIS service and go through the authorization process of this consent in the new Alior Business banking.

Deprecating previous versions API PIS and API AS (v2_1_1.1) on December 17th
After 8 months of maintaining in parallel both versions of API PIS (v2_1_1.1 & v2_1_1.2 ) and API AS (v2_1_1.1 & v2_1_1.2) in the production environment, we decided to deprecate the previous versions of our APIs.
We initially planned to deprecate versions of API PIS (v2_1_1.1) and API AS (v2_1_1.1) at the end of September 2020, however taking into account the active use of this version by TPPs the decision to deprecate it was postponed.
Therefore, we would like to inform that versions of API PIS (v2_1_1.1) and API AS (v2_1_1.1) will be finally deprecated on December 17th, 2020 in the production environment. Please take this change into account in your work on developing applications integrated with Alior Bank's Open API.

Unavailability of Open API | November 28th/29th, 2020
With regard to the planned merger of T-Mobile Banking Services branch with Alior Bank on 29.11.2020, Open API will be unavailable. The technical break will last from Saturday 28.11.2020 from 11 pm to Sunday 29.11.2020 until 7 pm.
Operational merger of T-Mobile Banking Services and Alior Bank
T-Mobile Poland and Alior Bank have decided to end their cooperation under the brand of T-Mobile Banking Services. Therefore as of November, 29th 2020 T-Mobile Banking Services customers will use Alior Online internet banking and Alior Mobile application.
What does this mean for TPP?
The operational merger of T-Mobile Banking Services and the Bank means that as of November, 29th 2020:
- both the brand and logo of T-Mobile Banking Services will not be present in the market - existing T-Mobile Banking Services customers after the operational merger with Alior Bank will use Alior Bank's online banking and mobile application;
- the consent granted to T-Mobile Banking Services will cease to apply after the operational merger of T-Mobile Banking Services and Alior Bank. In order to provide the services defined within PSD2, a new PSU consent will be required and a new token will be required from TPP;
- account numbers and transaction ids will remain unchanged.
This change is connected with carrying out the necessary IT works, therefore the planned unavailability of API will take place on 29th November, 2020. We will inform you about its details in a separate correspondence and will publish the information in the News section of the Developer Portal.
