v0.2.0

0.2.0 (2026-04-23)

0.2.0 improves the SDK ergonomics which means breaking changes. Please see the migration guide below for how to update your integration. The newer SDK style make it easier to construct calls and complex request body objects. It also improves the behavior of null vs. unspecified query parameters and body fields.

Migration Guide

Request body objects are now flattened into method keyword arguments. You no longer need to construct/pass the generated request body type explicitly.

Before:

sdk.subaccounts.update_sub_account(
  1,
  body=UpdateSubAccountBodyInput(
      nickname="New name",
  ),
)

After:

sdk.subaccounts.update_sub_account(
  1,
  nickname="New name",
)

Required body fields are now required keyword arguments:

sdk.subaccounts.create_sub_account(
  username="operator@example.com",
  password="correct horse battery staple",
)

Optional flattened request-body parameters now distinguish omitted fields from explicit JSON null.

If you omit an optional body argument, the SDK omits it from the JSON payload:

sdk.subaccounts.update_sub_account(1)
# Sends: {}

If you pass None, the SDK sends an explicit JSON null:

sdk.subaccounts.update_sub_account(1, nickname=None)
# Sends: {"nickname": null}

For query parameters, omitted parameters and None are both omitted from the query string:

sdk.transactions.list("merchant-123")
# No optional query params sent

sdk.transactions.list("merchant-123", limit=None)
# "limit" is omitted
