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.
