feat(setups): add klarna and stcpay actions, tamara fields, payment type by rodrigojara-cko · Pull Request #258 · checkout/checkout-sdk-python

rodrigojara-cko · 2026-10-26T14:21:13Z

Summary

Payment Setup in Python gains Klarna iban and action, stc pay action, and Tamara initialization and risk_assessment. payment_type gets its own enum with the six lowercase spec values (PaymentType.PAYLATER sends PayLater, which the API rejects with 422), local_date_time is typed as a date-time and last_payment_amount as a number. Members the spec does not have are marked deprecated. Every payment method keeps the base class it had before, and PaymentType can still be imported from the setups module.

Changes

checkout_sdk/payments/setups/setups.py:
- PaymentSetupPaymentType (REGULAR, RECURRING, MOTO, INSTALLMENT, PAY_LATER, UNSCHEDULED) on PaymentSetupsRequest.payment_type; the payments PaymentType is unchanged.
- PaymentType is still imported in the setups module (marked # noqa: F401 with a deprecation comment pointing to PaymentSetupPaymentType), so from checkout_sdk.payments.setups.setups import PaymentType keeps working.
- Klarna.iban, Klarna.action (KlarnaAction, KlarnaActionType), Stcpay.action (StcpayAction, StcpayActionType).
- Tamara keeps its base class PaymentSetupPaymentMethod and declares initialization itself (default disabled), plus risk_assessment (TamaraRiskAssessment).
- Bizum and Blik keep their base class PaymentMethodBase. Each one redeclares initialization with the same type and default and a deprecation comment, so callers and the request body do not change.
- PaymentSetupTerminal.local_date_time is datetime (a string is still sent unchanged); MerchantAccount.last_payment_amount is float.
- The initialization doc (PaymentMethodBase and Tamara) says that an update replaces the payment methods, so enabled must be sent again to keep a method enabled; the specification does not state this, it is the API's behaviour.
- The docs of Ideal.description, Knet.language and Bancontact.account_holder_name say that the specification marks them optional, but the API keeps the method invalid until they are sent.
- Deprecation comments on the members listed under Deprecated.
tests/payments/setups/payment_setups_serialization_test.py: literal wire keys, round trips through the response wrapper and the spec examples for every new field, every PaymentSetupPaymentType value, local_date_time as datetime and string, last_payment_amount 55.99, deprecated members still sent, the base classes of Bizum, Blik and Tamara, the PaymentType import from the setups module, and the deprecated PaymentMethodAction.client_token and session_id still sent and read under their keys.
tests/payments/setups/payment_setups_integration_test.py: uses PaymentSetupPaymentType.

API Reference

Deprecated

All of them will be removed in the next major version.

initialization on Bizum and Blik. Their spec schemas have no initialization and the API ignores it. No replacement.
payment_method_options on Klarna, Stcpay, Tabby and Bizum, and the PaymentMethodOptions and PaymentMethodOption classes. Use action on Klarna and stc pay; no replacement on Tabby and Bizum.
PaymentSetupInstrument.phone, account_holder and allow_update. Removed from the Payment Setups specification; the API accepts and ignores them. No replacement.
PaymentMethodAction.client_token and session_id. Not part of the PayPal or instrument action schemas, the two that use this class; the API ignores them. No replacement.
PaymentType imported from checkout_sdk.payments.setups.setups. Use PaymentSetupPaymentType for Payment Setups; PaymentType stays in checkout_sdk.payments.payments for /payments.

Breaking changes

None. No class changes its base class and no import is removed. Annotations change (payment_type, local_date_time, last_payment_amount), but Python does not enforce them and existing values are still sent as before. For payment_type, a PaymentType value keeps being sent as is: Regular is accepted, while PayLater keeps getting the 422 from the API, so code that sets PaymentType.PAYLATER should switch to PaymentSetupPaymentType.PAY_LATER. Responses read payment_type as the lowercase string, which compares equal to the PaymentSetupPaymentType value.

Follow-ups

Reported internally:

Order items and shipping keep the /payments types until the next major version.
Tamara now sends initialization: disabled by default, the same as the other methods on PaymentMethodBase.

🟢 Advisory review: Looks good to me

This PR still needs a human approval — wall-e cannot auto-approve it. For what it's worth, I read the diff and found nothing I'd block on.

Adds Klarna/stcpay actions and iban, Tamara initialization and risk_assessment, a new PaymentSetupPaymentType enum, and corrects field types (last_payment_amount to float, local_date_time to datetime); deprecated fields are preserved with comments and tested. The diff matches the stated intent, the integration test comparison is correctly simplified from a string-lower workaround to direct enum equality, and no error paths or migrations are obviously missing.

What I checked

PaymentSetupPaymentType.PAY_LATER serializes to 'pay_later' which the PR description acknowledges the API rejects with 422 — this is documented and is a pre-existing API constraint, not a new bug introduced here.
The integration test assertion change from str(response.payment_type).lower() == request.payment_type.lower() to response.payment_type == request.payment_type is correct because PaymentSetupPaymentType is a str-enum with lowercase values matching what the API returns.
Serialization tests verify round-trips for all new fields and confirm deprecated fields still appear in the wire body, providing adequate coverage for the truncated diff.
last_payment_amount changed from int to float annotation — Python doesn't enforce this at runtime so no breaking change, and existing integer values still serialize correctly.

⚠️ The diff was too large to read in full, so this review covers only part of the change.

✅ Auto-approved — this PR meets all Low-risk criteria.

All checks passed, no unresolved comments, and the change classification is:

no_low_class_matched
prod_source_modified
2.2.6_logical_extension:The PR adds new enum values, new fields, and new nested classes purely as natural extensions of existing payment setup abstractions without introducing new endpoints, external integrations, persisted data classes, auth changes, or background workers.

_{wall-e 2026.06.19-02 · policy 6b4ce2b3b45a…}

The specification types last_payment_amount as a number (example 55.99), but the sandbox stores and returns 55 for 55.99. The doc says so, so the type is not changed back and forth; the specification is reported separately.
