Add SubscriptionEvent wrapping/disable/enable and Invoice updateStatus/disable [PIP-311]

[wscourge]

Summary

Closes PIP-311

• Add auto-wrapping of flat params into subscription_event envelope for create/update/delete, with backward compatibility for already-enveloped inputs
• Add SubscriptionEvent.disable / SubscriptionEvent.enable endpoints
• Fix bug where passing undefined callback to _method() blocked request body from being sent
• Add Invoice.updateStatus and Invoice.disable endpoints
• Expand test coverage: body-wrapping verification, callback style, error handling, and Account include query param

Test plan

• All 220 tests pass (npm test)
• Verified envelope wrapping via nock body capture
• Verified backward compatibility (pre-wrapped params not double-wrapped)
• Verified error responses return correct status codes

Manual testing instructions

Prerequisites: Install the branch locally:

cd chartmogul-node
git checkout wiktor/pip-311-node-sdk-feature-updates
npm install
node

Then in the Node REPL:

const ChartMogul = require('./lib/chartmogul');
const config = new ChartMogul.Config('YOUR_API_KEY');

Use a staging/test account with existing subscription events and invoices.

1. SubscriptionEvent — flat params auto-wrapping (create)

Previously you had to wrap params in { subscription_event: { ... } }. Now flat params work too.

// Flat params (NEW) — should auto-wrap into envelope
const res = await ChartMogul.SubscriptionEvent.create(config, {
  customer_external_id: 'cus_test_001',
  data_source_uuid: 'ds_XXXX',
  event_type: 'subscription_start_scheduled',
  event_date: '2026-03-01T00:00:00Z',
  effective_date: '2026-04-01T00:00:00Z',
  external_id: 'evt_test_flat_' + Date.now(),
  subscription_external_id: 'sub_test_001'
});
console.log(res); // Should succeed and return { subscription_event: { id: ..., ... } }

// Envelope params (BACKWARD COMPAT) — should still work, no double-wrapping
const res2 = await ChartMogul.SubscriptionEvent.create(config, {
  subscription_event: {
    customer_external_id: 'cus_test_001',
    data_source_uuid: 'ds_XXXX',
    event_type: 'subscription_start_scheduled',
    event_date: '2026-03-01T00:00:00Z',
    effective_date: '2026-04-01T00:00:00Z',
    external_id: 'evt_test_envelope_' + Date.now(),
    subscription_external_id: 'sub_test_001'
  }
});
console.log(res2); // Should succeed identically

✅ Expected: Both calls succeed and return the created subscription event.

---

2. SubscriptionEvent — flat params auto-wrapping (update)

// Update using flat params with id
const updated = await ChartMogul.SubscriptionEvent.updateWithParams(config, {
  id: <EVENT_ID_FROM_STEP_1>,
  plan_external_id: 'plan_gold_monthly'
});
console.log(updated); // Should show updated plan_external_id

// Update using flat params with external_id + data_source_uuid
const updated2 = await ChartMogul.SubscriptionEvent.updateWithParams(config, {
  external_id: 'evt_test_flat_XXXX',
  data_source_uuid: 'ds_XXXX',
  plan_external_id: 'plan_silver_monthly'
});
console.log(updated2);

✅ Expected: Both calls succeed and return the updated subscription event.

---

3. SubscriptionEvent — flat params auto-wrapping (delete)

// Delete using flat params with id
await ChartMogul.SubscriptionEvent.deleteWithParams(config, {
  id: <EVENT_ID>
});
// Should return empty object {}

// Delete using flat params with external_id + data_source_uuid
await ChartMogul.SubscriptionEvent.deleteWithParams(config, {
  external_id: 'evt_test_envelope_XXXX',
  data_source_uuid: 'ds_XXXX'
});
// Should return empty object {}

✅ Expected: Both calls succeed with empty response {}.

---

4. SubscriptionEvent — disable / enable

// First create an event to work with (or use an existing event ID)
const event = await ChartMogul.SubscriptionEvent.create(config, {
  customer_external_id: 'cus_test_001',
  data_source_uuid: 'ds_XXXX',
  event_type: 'subscription_start_scheduled',
  event_date: '2026-03-01T00:00:00Z',
  effective_date: '2026-04-01T00:00:00Z',
  external_id: 'evt_disable_test_' + Date.now(),
  subscription_external_id: 'sub_test_001'
});
const eventId = event.subscription_event.id;

// Disable
const disabled = await ChartMogul.SubscriptionEvent.disable(config, eventId);
console.log(disabled); // subscription_event.disabled should be true

// Enable
const enabled = await ChartMogul.SubscriptionEvent.enable(config, eventId);
console.log(enabled); // subscription_event.disabled should be false

// Error case — nonexistent ID should return 404
try {
  await ChartMogul.SubscriptionEvent.disable(config, 999999999);
} catch (e) {
  console.log(e.status); // Should be 404
}

✅ Expected: Disable returns disabled: true, enable returns disabled: false, nonexistent ID returns 404.

---

5. Invoice — updateStatus

// Void an existing invoice (use a real invoice UUID from your test account)
const invoiceUuid = 'inv_XXXX';

const result = await ChartMogul.Invoice.updateStatus(config, invoiceUuid, {
  status: 'void'
});
console.log(result); // Should show status: 'void'

// Error case — invalid status transition should return 422
try {
  await ChartMogul.Invoice.updateStatus(config, invoiceUuid, {
    status: 'invalid_status'
  });
} catch (e) {
  console.log(e.status); // Should be 422
}

✅ Expected: Valid status update succeeds, invalid status returns 422.

---

6. Invoice — disable

const invoiceUuid = 'inv_XXXX';

const disabled = await ChartMogul.Invoice.disable(config, invoiceUuid);
console.log(disabled); // Should show disabled: true, disabled_at, disabled_by

// Error case — nonexistent invoice should return 404
try {
  await ChartMogul.Invoice.disable(config, 'inv_nonexistent');
} catch (e) {
  console.log(e.status); // Should be 404
}

✅ Expected: Disable succeeds with disabled: true + timestamps, nonexistent UUID returns 404.

Pull request overview

Updates the ChartMogul Node SDK to support newer API behaviors for Subscription Events, Invoices, and Account retrieval by adding/adjusting client methods and expanding test coverage for these behaviors.

Changes:

• Add support for flat (non-enveloped) SubscriptionEvent params by auto-wrapping into a subscription_event envelope, while keeping backward compatibility for already-enveloped inputs.
• Add SubscriptionEvent.enable/disable and Invoice.updateStatus/disable SDK methods and corresponding tests.
• Expand invoice/account test fixtures and assertions to cover new/optional response fields (e.g., error, id, and account include query param).
