README

Shared payment ledger package for PayID ecosystem.

Requirements

PHP ^8.3
Laravel ^12.0|^13.0 (illuminate/database, illuminate/support)

CI and Release

CI workflow runs on push/PR to main:
- composer validate --strict
- composer lint-check
- composer test
Auto tag release workflow reads version from composer.json at:
- extra.release.version
On push to main (when composer.json changes), the workflow:
- creates git tag v<version> if not exists
- creates GitHub Release with generated notes

Release steps for maintainers:

Bump extra.release.version in composer.json.
Merge/push to main.
Workflow creates tag and GitHub release automatically.

Scope

Persist payment transaction lifecycle (payment_transactions).
Persist webhook delivery and processing trail (payment_webhook_events).
Provide service contract for recording and updating transaction state.

Schema Notes

Transaction identity is composite: provider + merchant_order_id.
If idempotency_key is provided, transaction upsert identity becomes provider + idempotency_key.
Optional polymorphic linkage is available via subject_type + subject_id.
Webhook table stores replay-safe event_fingerprint and processing audit fields.

Terminology Glossary

This package uses gateway-neutral naming so one schema can serve multiple providers.

provider: payment gateway identifier (midtrans, stripe, xendit, doku, paddle, etc).
merchant_order_id: merchant-side business reference for the payment intent. Common equivalents in other systems: external_id, invoice_number, order_code.
provider_transaction_id: gateway-side transaction/reference ID (pi_..., txn_..., etc).
idempotency_key: client/service generated deduplication key for retry-safe writes.
subject_type and subject_id: domain link (similar to polymorphic relation by convention). Examples: order, subscription, marketplace_order, wallet_topup.
event_fingerprint: deterministic unique value to detect webhook replay/retry.

Naming Guidelines

Recommended conventions for production teams:

Keep provider lowercase slug and stable (stripe, not Stripe/STRIPE).
Keep merchant_order_id immutable after first successful write.
Use idempotency_key for all external-call retries (charge, confirm, capture, etc).
Use consistent subject_type vocabulary across services (document in one place).
Put gateway-specific extras in metadata, keep core columns provider-agnostic.

Gateway Field Mapping (Practical)

Midtrans: merchant_order_id <= order_id, provider_transaction_id <= transaction_id.
Stripe: merchant_order_id <= invoice/external order reference, provider_transaction_id <= payment_intent/charge ID.
Xendit: merchant_order_id <= external_id, provider_transaction_id <= payment/invoice transaction ID.
DOKU: merchant_order_id <= merchant invoice/order number, provider_transaction_id <= DOKU transaction reference.
Paddle: merchant_order_id <= merchant checkout/invoice reference, provider_transaction_id <= Paddle transaction ID.

Non-scope

Invoice domain model.
Subscription orchestration.
Provider API adapter logic.

Install

composer require aliziodev/payid-transactions

Publish

php artisan vendor:publish --tag=payid-transactions-config
php artisan vendor:publish --tag=payid-transactions-migrations

Usage

Resolve ledger service from container:

$ledger = app(\Aliziodev\PayIdTransactions\Contracts\TransactionLedger::class);

$ledger->upsertStatus([
    'provider' => 'midtrans',
    'merchant_order_id' => 'ORDER-1001',
    'status' => 'paid',
    'amount' => 100000,
    'currency' => 'IDR',
    'subject_type' => 'subscription',
    'subject_id' => '01JABCDEF...',
]);

Prune old webhook audit rows:

php artisan payid-transactions:prune-webhooks --days=90

Webhook Audit Example

Use webhook event store for retries/replay visibility and processing outcomes:

$event = $ledger->recordWebhookEvent([
    'provider' => 'stripe',
    'event_fingerprint' => hash('sha256', 'stripe|evt_123|pi_123'),
    'external_event_id' => 'evt_123',
    'merchant_order_id' => 'INV-2026-05-ACME-01',
    'provider_transaction_id' => 'pi_3Qx...',
    'signature_valid' => true,
    'payload' => ['type' => 'invoice.paid'],
    'received_at' => now(),
]);

$ledger->markWebhookProcessed($event, true);

Suggested Subject Mapping

ecommerce order: subject_type = order, subject_id = order_id
subscription billing: subject_type = subscription, subject_id = subscription_id
marketplace order: subject_type = marketplace_order, subject_id = marketplace_order_id
digital goods/license: subject_type = license_order, subject_id = license_order_id
wallet top-up: subject_type = wallet_topup, subject_id = topup_id
