Fields
pacingPeriod

enum (PacingPeriod)

Required. The time period in which the pacing budget will be spent.

When automatic budget allocation is enabled at the insertion order via [auto_budget_allocation][InsertionOrderBudget.auto_budget_allocation], this field is output only and defaults to PACING_PERIOD_FLIGHT.
pacingType

enum (PacingType)

Required. The type of pacing that defines how the budget amount will be spent across the pacingPeriod.
Union field daily_max_value. Applicable when pacing_period is set to be PACING_PERIOD_DAILY. daily_max_value can be only one of the following:
dailyMaxMicros

string (int64 format)

Maximum currency amount to spend every day in micros of advertiser's currency.

Applicable when the budget is currency based. Must be greater than 0. For example, for 1.5 standard unit of the currency, set this field to 1500000.

The value assigned will be rounded to whole billable units for the relevant currency by the following rules: any positive value less than a single billable unit will be rounded up to one billable unit and any value larger than a single billable unit will be rounded down to the nearest billable value. For example, if the currency's billable unit is 0.01, and this field is set to 10257770, it will round down to 10250000, a value of 10.25. If set to 505, it will round up to 10000, a value of 0.01.
