Our API is reliable

  • We stick to the standards

    SOAP and XML is so old school

    We move with the times. Our API is RESTful with JSON as the data exchange format. We keep up-to-date documentation in Apiary.

    Just add your API key to the request header and let our programs talk.

  • We won’t break your code

    Once released, stays released

    Our API doesn’t change on the fly. We won’t change our implementation so you don’t have to worry your app will stop working out of the blue.

    We version our API and we will inform you well in advance if we stop supporting older versions.

  • Fair rate limiting

    We won’t hold you back

    Each of our APIs has a limited number of queries you can run every day. We set the limit high enough for development as well as production.

    We’ll send you an e-mail in advance if your app approaches the daily limit.

    We will be happy to discuss changing the rate limits if they are too low for your needs. Feel free to contact us at developers@csas.cz.

  • Safety first

    Maximum safety with minimum effort

    All communication with API is encrypted with HTTPS.

    What is more, API requests dealing with money and accounts are additionally secured with HMAC signature.

    When it comes to security, we pay special attention to mobile devices.

  • We support your success

    Increase the value of your apps

    Thanks to the integration with our API, your app can benefit from our banking system.

    You can offer a unique value to your customers and partners.

  • Clear vision

    We provide the best bank API in the world

    We are quickly moving forward. There is a new feature every 30 hours! We plan to enable API for active financial transactions.

New developers portal just launched

After months of intensive preparations, we have launched the new developers portal Erste API Hub (https://www.ersteapihub.com). You can find here complete documentation and testing environment of Česká spořitelna API - including other APIs beyond PSD2. Later, we will also provide more APIs and more banks from Erste Group.

Documentation is immediately accessible to everyone without registration.

After short registration you will be able to manage your own team, including individual members - who only develops and those who negotiate with the bank on contractual and legal aspects.

Last but not least, you will also have a sandbox where you can fully test all APIs and their behavior before going into production.

What happens to current apps?

Existing API keys and applications are still working, but in the coming months we will be dealing with migration to the new portal environment. More information on this topic will follow.

Questions and comments?

In the coming weeks and months, we are preparing further improvements to the portal and above all documentation.

If you have any questions or comments, please let us know at feedback@ersteapihub.com
