GET /accounting/accounting-periods/{id}

Read-only: Reads and returns; changes nothing.

Retrieves an accounting period. The record is one period for one legal entity and one accounting book, so the same period has a separate record for each entity and book. The response includes whether the period accepts new journal entries for that entity and book (postable), and the period-close checklist (closeTasks).

Parameters

Name In Type Required Description
Api-Version header string · v1 yes The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version v1.
id path string yes The unique identifier of the entity-book accounting period record you want to retrieve. This is the id of a record from GET accounting/accounting-periods, not the shared accountingPeriodId.

Response

200 Success

Under data (getAccountingPeriodOutput):

Field Type Required Description
id string yes The unique identifier for this entity-book accounting period row. This identifies the (entity, book, period) combination, not the shared accounting period.
accountingPeriodId string no The identifier of the underlying accounting period, shared by every entity that uses this fiscal calendar. See id on GET accounting/accounting-periods/:id.
entityId string no The identifier of the legal entity this status belongs to. See id on GET base/entities. Absent only when the entity-book link is broken.
entityName string no The name of the legal entity this status belongs to.
bookId string no The identifier of the accounting book this status belongs to. A period is opened and closed per book. See id on GET accounting/books/:id.
bookName string no The name of the accounting book this status belongs to.
fiscalCalendarId string no The identifier of the fiscal calendar this period belongs to. See id on GET accounting/fiscal-calendars/:id. Absent when the period was deleted from under its status row.
fiscalCalendarName string no The name of the fiscal calendar this period belongs to.
periodName string no The display name of the period as its fiscal calendar defines it, for example 'Jan 2026'. The format varies by calendar, so do not parse it. Match on dates instead.
fiscalYear string no The fiscal year label this period belongs to, for example 'FY2024'. Set by the calendar, so it need not match the calendar year of startDate.
fiscalQuarter string no The fiscal quarter label this period belongs to, for example 'Q1 2026'.
startDate date no The first day of the period, inclusive. Format YYYY-MM-DD. Absent only when the underlying period was deleted.
endDate date no The last day of the period, inclusive. Format YYYY-MM-DD.
durationDays number no The number of days the period spans, both bounds inclusive. Absent when startDate or endDate is.
status string yes The status this entity and book have put the period in. Possible values: 'created' (generated, not yet opened), 'open', 'closed', 'reopened'. Only 'open' and 'reopened' accept postings.
postable boolean yes Whether the period currently accepts postings for this entity and book, true when its status is 'open' or 'reopened'. This does not account for journal-type-specific locks.
postableReason string yes Why the period does not accept postings, for example 'status is closed'. Empty when it is postable.
reopeningReason string no The free-text reason recorded when the period was reopened. Set only when status is 'reopened'.
reopenedByCascade boolean no Whether this period was reopened as a side effect of reopening a later one, rather than directly.
hasTransactions boolean no Whether at least one journal entry line has been posted into the underlying period, by any entity.
lastModifiedDate date-time yes The date and time this status row last changed, in UTC. Format YYYY-MM-DDTHH:mm:ss.sssZ. It changes when the period is opened, closed or reopened for this entity and book.
closeTasks array<object> no The period-close checklist for this entity and book, one entry per task. An empty array when the row has no tasks yet. Check isExecutable before running a task with POST accounting/period-status/:id/execute-task.
closeTasks[].taskCode string yes The code identifying the task, and the value to pass as task to POST accounting/period-status/:id/execute-task. The forward tasks, for example 'open', 'close', 'reopen', 'lockAP', 'lockAR', 'lockRevenue', 'lockJournals', 'runRevaluation', 'calculateConsolidationRates'. The task that undoes one is in reverseTaskCode.
closeTasks[].reverseTaskCode string no The code of the task that undoes this one, for example 'unlockAP' for 'lockAP'. Empty when the task cannot be reversed.
closeTasks[].isExecuted boolean yes Whether this task has already run for this entity-book period.
closeTasks[].isExecutable boolean yes Whether this task can run now. It is false for a task already done and for one whose preconditions are unmet. notExecutableReason says which.
closeTasks[].notExecutableReason string no Why the task cannot run now. Present only when isExecutable is false and a reason is available.
closeTasks[].isReversible boolean yes Whether the task that undoes this one can run now.
closeTasks[].notReversibleReason string no Why the reversal cannot run now. Present only when isReversible is false and a reason is available.
closeTasks[].notApplicable boolean no Whether this task does not apply to this entity-book period at all, for example a consolidation task on an entity that does not consolidate. Such a task is neither executed nor executable and does not block the close.
closeTasks[].message string no A human-readable, translated description of the task's state: the applied message when it has run, the not-applied message when it has not, or the not-applicable message when it does not apply.
closeTasks[].lastModifiedDate date-time no The date and time this task's state last changed, in UTC. Format YYYY-MM-DDTHH:mm:ss.sssZ. Absent on a task that has never run.
closeTasks[].lastModifiedBy string no The identifier of the user who last changed this task's state. Absent on a task that has never run.
