Naming: This concept is called Accounting Routes in the Lerian Console and product documentation. In the API and SDKs the transaction-level route is represented by the
transactionRoute resource (and transaction-route endpoints). The two terms refer to the same thing.- Accounting Routes define the complete structure of a transaction — the required sequence of operations and how they fit together to form a valid financial event.
- Operation Routes define the rules for each individual operation (or “leg”) of that transaction, including the expected account type or specific account, the accounting annotation, and whether it’s a debit or credit.
You define the validation patterns through Operation Routes and Accounting Routes. Midaz ensures your transactions comply with these rules before processing.
What are Accounting Routes for?
Accounting Routes provide structured control over your financial operations by separating transaction logic from business code. Instead of hardcoding validation rules in your application, you configure reusable patterns that ensure every financial movement follows your organization’s requirements. These entities are dedicated to linking Transactions and Operations from the Midaz ledger to higher-level abstractions that facilitate integration with specialized plugins and external systems, especially for accounting and treasury abstractions. The structured annotations and classifications create a standardized vocabulary that other components can understand and leverage. This approach delivers:
- Consistency: All transactions follow predefined structures regardless of where they originate.
- Flexibility: Adapt your ledger design to match your business needs without code changes.
- Integrity: Automatic validation prevents malformed transactions from affecting your ledger.
- Maintainability: Centralized configuration makes it easier to update financial rules as your business evolves.
- Interoperability: Business-semantic fields enable seamless integration with accounting plugins and external financial systems.
Working with Accounting Routes
To use Accounting Routes, you must complete the initial configuration followed by ongoing transaction execution. Here’s your step-by-step process:
Initial Setup
1. Configure Ledger for transaction route validation
To activate transaction route validation for a specific Ledger, enable the validation settings through the Ledger Settings API. This controls whether transactions in that Ledger must comply with your configured routes.validateRoutes: When enabled, every transaction must reference a valid transaction route.validateAccountType: When enabled, account types are validated against operation route rules.
2. Create Operation Routes
Create Operation Routes that define validation rules and behavior for individual transaction components. Key fields:- title: Brief label that identifies the operation route.
-
code (deprecated): a legacy external reference kept for backward compatibility. It is not written to operations — the engine records the resolved rubric’s
code(fromaccountingEntries) asrouteCodeon each operation instead. - description: Optional detailed explanation.
- metadata: Key-value pairs for business context and custom categorization.
-
operationType: The accounting direction for this route —
source,destination, orbidirectional.source— Identifies accounts where funds originate (debit side).destination— Identifies accounts where funds are sent (credit side).bidirectional— Applies to both sides of the transaction, acting as both source and destination.
-
account: Optional validation rules specifying required account type or specific account.
- ruleType: Type of account validation rule (
account_type,alias). - validIf: The expected value that must match for validation to pass.
- ruleType: Type of account validation rule (
- accountingEntries: Optional accounting entries for each action type. See Accounting Entries below.
- Target Specific Account
- Target Account Type
accountingEntries field, mapping each transaction-lifecycle stage to the correct double-entry accounting codes. The full action-type model, debit/credit requirements, and validation matrix are covered in Configure Accounting Entries (Actions) below.
A route with accounting entries configured:
The
operationType field also supports bidirectional, which allows the route to operate in both directions — useful for routes that handle both sending and receiving, or for operations that may need to be reversed.3. Build Accounting Routes
Complete your setup by combining Operation Routes into Accounting Routes (thetransactionRoute resource in the API). These define your complete transaction patterns, mapping how different operations work together to form balanced financial events that match your business processes.
4. Configure Accounting Entries (Actions)
Each Operation Route can include Accounting Entries — structured rubrics that define how debit and credit entries are recorded for each type of transactional event (direct, hold, commit, cancel, revert). They are what the engine uses to resolve which accounts get debited and credited for each action, and they determine the routeCode/routeDescription annotations written on each operation.
Whether a missing rubric is tolerated (graceful) or rejected with 0117 ErrAccountingRouteNotFound (strict) is controlled by accounting.validateRoutes in the Ledger Settings.
The accounting-entry actions, the debit/credit requirements per operation type, the graceful vs. strict validation modes, and full configuration examples are documented in detail on the Accounting Entries page. This section covers only how rubrics attach to Operation Routes.
accountingEntries block (see Option C under Create Operation Routes above), with one entry per action and a debit and/or credit rubric depending on the route’s operationType:
- Source routes require the debit rubric.
- Destination routes require the credit rubric.
- Bidirectional routes require both debit and credit rubrics.
Accounting entries validation matrix
Not every combination ofoperationType and action is valid. Midaz enforces a strict validation matrix when you create or update an Operation Route — if the rules aren’t met, the request is rejected before persisting.
Understanding this matrix is critical for integrators: sending an invalid combination returns error 0166 (field required) or 0162/0165 (scenario not allowed for direction).
source
destination
bidirectional
An entry with neither
debit nor credit is always rejected, regardless of operation type or action.- Reserve group atomicity: If you define
hold, you must also definecommitandcancel(and vice versa). These three actions form an atomic group — you can’t configure one without the others. - Direct is mandatory: If any other action (
hold,commit,cancel,revert) is defined,directmust also be present. It serves as the baseline entry for the operation route.
Ongoing Operations
5. Execute Validated Transactions
With your routing configuration in place, you can now submit transactions with confidence by including the ID of the previously created Accounting Route in your transaction request. Midaz will automatically validate the transaction against your defined routing patterns, ensuring consistency and integrity across all financial operations. For the previously configured Accounting Route and Operation Routes examples, the system composes the following validation structure:@user/wallet_123 account matches the user_wallet account type rule, and @external/BRL matches the exact alias requirement, ensuring the transaction follows your configured routing patterns.
Route fields on operations
When route validation is enabled and accounting entries are configured, every successfully processed operation will include two additional fields populated from the matched rubric:- routeCode — The
codeof the resolvedAccountingRubricfor that operation’s action and direction. - routeDescription — The description of the resolved accounting rubric, populated alongside
routeCode.
Managing Operation and Accounting Routes
To configure your Operation Routes, use the following endpoints:
- Create an Operation Route — Define a new accounting rule for your operations.
- List Operation Routes — View all configured Operation Routes.
- Retrieve an Operation Route — Get detailed information on a specific Operation Route.
- Update an Operation Route — Modify existing accounting rules.
- Delete an Operation Route — Remove an outdated or unused Operation Route.
transactionRoute resource in the API), use the following endpoints:
- Create a Transaction Route — Define new routing logic to connect transactions to accounting operations.
- List Transaction Routes — View all configured Transaction Routes.
- Retrieve a Transaction Route — Get details of a specific Transaction Route.
- Update a Transaction Route — Modify existing routing criteria.
- Delete a Transaction Route — Remove routes that are no longer applicable.
