[MI-1355 ] fix: refunds multiple refunds - #48
Conversation
WalkthroughThe Braintree payment plugin now preserves original sale transaction IDs during refunds, stores gateway results in refund history, and includes transaction statuses in refund errors. Tests and documentation cover these behaviors. The package version changes from ChangesBraintree refund handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to When refunds are retried with allowRefundOnRefunded enabled, some failed or voided provider responses may be treated as successful refunds, leaving incorrect refund totals and financial state. The PR is not merge-ready until the fallback only handles genuine already-refunded responses and the behavior is covered by tests. Possibly related PRs

Preserve status errors when allowRefundOnRefunded is enabled.
The catch block at Line 243-248 treats any message containing refunded or cannot be refunded as proof that the transaction was already refunded. Both messages introduced here match that condition. A voided, failed, or void-disabled transaction can therefore return a successful local refund and increase refundedTotal, even though Braintree performed no mutation.
Use a structured gateway error code or a dedicated error type for the already-refunded fallback. Re-throw these status-specific errors. Add tests with allowRefundOnRefunded: true that verify rejection and unchanged refund totals.
Also applies to: 314-318

Review
Verdict: approve with nits. Against main, this is not a new sale-id rewrite. That behavior is already on main (refundPayment already calls buildRefundPaymentOutput(input, action.transaction, …)). This PR locks it in with tests, puts status on thrown errors, and bumps the package.
Finding
[P3] Add a 0.2.4 changelog entry — plugins/braintree-payment/CHANGELOG.md
package.json goes 0.2.2 → 0.2.4, but CHANGELOG.md still ends at 0.2.2. The README “Upgrading to 0.2.2” section is also unchanged except for the quoted error text. Anyone installing 0.2.4 has no release notes for what actually shipped.
What is actually different vs main
| Area | Change |
|---|---|
braintree-base.ts / braintree-import.ts |
Thrown MedusaError messages now include because it's in status {status}. Duplicate logger.error before those throws was removed. Comments only on the refund-output path. |
| Tests | Assert data.transaction.id stays the sale. New case: two sequential partial refunds both call refund('t1', …) and history is [r1, r2]. Explicit voided rejection. |
| Docs / version | Error-string docs; version 0.2.4. |
The sequential-refund test is the useful part. It would have caught the old bug (session transaction overwritten with credit r1).
CodeRabbit comment — not a blocker on this PR
CodeRabbit flags allowRefundOnRefunded treating any message containing "refunded" as already-refunded. That heuristic already matched the old strings (cannot be refunded / cannot be refunded right now). This PR did not introduce that swallow. Worth a follow-up on import refunds, not a reason to bounce this PR.
Residual risk (pre-existing)
- Sessions that already stored a credit id on
data.transactionare not migrated. New refunds from a healthy session are fine. - Import provider still writes
refundResponse.transactionontodata.transaction, but later refunds usesession.transactionId, so that path is less exposed.
Test plan
- Settled sale: partial refund, then a second partial refund — both Braintree calls use the original sale id.
disableVoidTransactions: authorized sale stillINVALID_DATAwith status in the message.- Voided / failed:
NOT_FOUND, no gateway mutation. - Confirm whether
0.2.3was ever published; if not, skipping it is fine once changelog exists.
I would approve after a changelog line for 0.2.4. The refund-id logic we care about is already on main; this PR mainly prevents it from regressing.
