Handling errors

When using the TBPlusSDK, all API requests are wrapped with internal error handling logic. If the API returns an error, a custom exception TatrapayPlusApiException is raised. This allows you to catch and respond to failures in a structured way.

Basic usage​

Wrap all client calls in a try/except block to catch and handle TatrapayPlusApiException.

from tatrapayplus.errors import TatrapayPlusApiException

try:
    payment_response = client.create_payment(
        request=payment_data,
        redirect_uri="https://tatrabanka.sk/",
        ip_address="127.0.0.1"
    )
except TatrapayPlusApiException as e:
    print("Payment failed:", e)
    # Handle error

Error body types​

When a TatrapayPlusApiException is raised, the error_body attribute will contain one of three structured model instances, depending on which endpoint was called and what kind of error occurred.

Supported models​
