Upgrading from python-fints 1.x to 2.x

This library has seen a major rewrite in version 2.0 and the API has changed in a lot of places. These are the most important changes to know:

  • The get_statement method was renamed to get_transactions. → Reading account transactions
  • The start_simple_sepa_transfer method was renamed to simple_sepa_transfer and no longer takes a TAN method and TAN medium description as an argument. → Sending SEPA transfers
  • The start_sepa_transfer method was renamed to sepa_transfer and no longer takes a TAN method and TAN medium description as an argument. The new parameter pain_descriptor should be passed with the version of the PAIN format, e.g. urn:iso:std:iso:20022:tech:xsd:pain.001.001.03. → Sending SEPA transfers
  • The start_sepa_debit method was renamed to sepa_debit and no longer takes a TAN method and TAN medium description as an argument. The new parameter pain_descriptor should be passed with the version of the PAIN format, e.g. urn:iso:std:iso:20022:tech:xsd:pain.008.003.01. Also, a new parameter cor1 is optionally available. → Creating SEPA debits
  • Working with TANs has changed a lot. get_tan_methos has been renamed to get_tan_mechanisms and has a new return data type. The chosen TAN method is now set on a client level with set_tan_mechanism and set_tan_medium. You can find more information in the chapter Working with TANs and a full example in the chapter Sending SEPA transfers.
  • Debug logging output now contains parsed syntax structures instead of data blobs and is much easier to read.
  • A new parser for FinTS has been added that is more robust and performs more validation.

In exchange, you get a couple of great new features:
