Add missing features and new endpoints

[wscourge]

Summary

• PIP-304: Expose errors field on LineItem and Transaction schemas (Invoice already had it)
• PIP-120 / PIP-76: Add id, churn_recognition, churn_when_zero_mrr fields to Account schema; support include query param on /account
• Invoice endpoints: Add Invoice.update_status (PATCH) and Invoice.disable (PATCH /invoices/{uuid}/disable)
• SubscriptionEvent: Add destroy() / modify() wrappers that accept flat params instead of requiring subscription_event: {...} envelope; add disable() / enable() convenience methods

Backwards compatibility review

All changes are purely additive — no existing public API surface was modified or removed.

File	Change	Breaking?
account.py	Added id, churn_recognition, churn_when_zero_mrr schema fields (allow_none=True)	No — old responses without these fields still deserialize correctly
invoice.py	Added errors field to LineItem._Schema (allow_none=True)	No — additive field
invoice.py	Added Invoice.update_status and Invoice.disable methods	No — new methods only
transaction.py	Added errors field to Transaction._Schema (allow_none=True)	No — additive field
subscription_event.py	Added disabled field to schema (allow_none=True)	No — additive field
subscription_event.py	Added destroy, modify, disable, enable classmethods	No — new methods; existing destroy_with_params / modify_with_params unchanged
resource.py	Added "disable" to uuid-required validation list	No — only affects the new Invoice.disable method; no existing method used this name

Test plan

• Existing 103 tests still pass
• Added 27 new tests covering happy paths, error paths (404), edge cases (None/absent errors, envelope passthrough, no-mutation, missing uuid validation)
• 130 total tests passing

Testing instructions

Integration tests were run against account WiktorOnboarding (acc_d0ea225e-f0f1-40ab-92cf-659dce5f2b76). To obtain the API key, impersonate wiktor@chartmogul.com in the admin panel and find it under Profile > API keys. The full test script is at sdks/tests/py/test_pip_310.py — set the CHARTMOGUL_API_KEY env var and run it.

cd sdks/py
pip3 install -e .
export CHARTMOGUL_API_KEY='...'

import chartmogul
config = chartmogul.Config(os.environ['CHARTMOGUL_API_KEY'])

# LineItem/Transaction schema supports errors field
# (API omits the key when no validation errors exist)

Invoice.update_status

# Note: API returns 202 (async), SDK returns None

Invoice.disable

# Note: returns 404 for some invoices (e.g. Stripe-sourced); works for custom API invoices
try:
    result = chartmogul.Invoice.disable(
        config,
        uuid='inv_YOUR_CUSTOM_API_INVOICE'

Invoice.all with query params

assert len(result.invoices) > 0

SubscriptionEvent.disabled schema field

sevs = chartmogul.SubscriptionEvent.all(config).get()
se = sevs.subscription_events[0]
assert isinstance(se.disabled, bool)
print(f"Event {se.id}: disabled={se.disabled}")

SubscriptionEvent.modify — flat params and envelope passthrough

# Flat params (auto-wrapped into subscription_event envelope)
se = chartmogul.SubscriptionEvent.modify(
    config, data={'id': 543978478}
).get()
assert se.id == 543978478

# Envelope passthrough (already wrapped — passed through as-is)
se = chartmogul.SubscriptionEvent.modify(
    config, data={'subscription_event': {'id': 543978478}}
).get()
assert se.id == 543978478

SubscriptionEvent.destroy — flat params and envelope passthrough

import time

# Create a temporary event
ts = int(time.time() * 1000)
se = chartmogul.SubscriptionEvent.create(config, data={
    'subscription_event': {
        'external_id': f'test_destroy_{ts}',

        'effective_date': '2026-03-25T00:00:00Z',
    }
}).get()

# Destroy with flat params
chartmogul.SubscriptionEvent.destroy(config, data={'id': se.id}).get()

# Also works with external_id + data_source_uuid, and envelope passthrough

SubscriptionEvent.disable and enable

# Disable with flat params
se = chartmogul.SubscriptionEvent.disable(
    config, data={'id': 543978478}

# Enable with flat params
se = chartmogul.SubscriptionEvent.enable(
    config, data={'id': 543978478}

assert isinstance(se, chartmogul.SubscriptionEvent)

# Works with external_id + data_source_uuid

# Works with envelope passthrough
se = chartmogul.SubscriptionEvent.disable(
    config, data={'subscription_event': {'id': 543978478}}

# Re-enable to clean up
chartmogul.SubscriptionEvent.enable(config, data={'id': 543978478}).get()

Pull request overview

This PR updates the Python SDK to support additional API response fields and adds/adjusts client methods for invoice and subscription event operations, with accompanying test coverage.

Changes:

• Add deserialization support for errors on invoice line items/transactions and for additional account fields (id, churn settings).
• Add invoice endpoints for updating status and disabling invoices.
• Add SubscriptionEvent.destroy/modify/disable/enable helpers that accept “flat” params and wrap them in the required subscription_event envelope, plus tests for these behaviors.
