Request Body

Analysis parameters.

application/json: object

Name	Type	Input Shape	Values	Description	Value Required
`aggregationUnits`	array<string>	-	hour, dayofweek, daytype, daytypehour	Time-series dimensions to generate when generateTimeSeries is true. Valid values: hour, dayofweek, daytype, daytypehour. An empty array generates all four.	N
`componentTimeRange`	object	component: string (values: Start, End, Both); timeFrom: string; timeTo: string	-	Time-of-day window and journey endpoint constraint applied to the analysis.	Y
`connectorAndCondition`	boolean	-	-	When true, journeys must pass through all connectors; when false (default), passing through at least one is sufficient.	N
`connectorIds`	array<string>	-	-	Encoded zone IDs that journeys must pass through. Provide either connectorIds or connectors, not both.	N
`connectors`	array<object>	code: string; iso_3166_2: string; type: string (values: Country, State, County, City, FSA, ZIP, TAZ, CTR, Custom, Segment, RelatedRoad)	-	Zone objects that journeys must pass through (subject to connectorAndCondition). Provide either connectors or connectorIds, not both.	N
`customAggregationValues`	array<object>	aggregationValue: string; hourEnd: integer; hourStart: integer	-	Custom hourly range buckets appended to the time-series output in addition to any aggregationUnits selections.	N
`dateRanges`	array<object>	dateFrom: string; dateTo: string	-	Date ranges to include in the analysis. Maximum 4 non-overlapping ranges, each up to 365 days. Results are aggregated across all ranges unless isTrendAnalysis is true.	Y
`daysOfWeek`	array<integer>	-	1, 2, 3, 4, 5, 6, 7	Days of the week to include (1=Sunday … 7=Saturday). An empty array includes all days.	N
`destinationIds`	array<string>	-	-	Encoded destination zone IDs. IDs use passThrough=false. Provide either destinationIds or destinations, not both.	N
`destinations`	array<object>	code: string; iso_3166_2: string; passThrough: string (values: false, true, only); type: string (values: Country, State, County, City, FSA, ZIP, TAZ, CTR, Custom, Segment, RelatedRoad)	-	Destination zone objects for the analysis. passThrough is optional and accepts 'false', 'true', or 'only'; omitted values default to 'false'. Provide either destinations or destinationIds, not both.	N
`generateTimeSeries`	boolean	-	-	When true, a time-series breakdown child analysis is generated for each aggregation unit. Results are retrievable via GET /api/v2/origin-destination/corridor-matrix/{id}/time-series once the job is complete.	Y
`industries`	array<string>	-	agriculture, mining, utilities, construction, manufacturing, wholesale, retail, transportation_and_warehousing, information_and_cultural, finance_and_insurance, real_estate, science_and_technology, management, administrative_and_support, education, health_care, arts_and_entertainment, accommodation_and_food, public_administration, other_services, unclassified	Named industry IDs from GET /api/v2/filters/industries (e.g. 'manufacturing', 'retail'). Resolved to NAICS codes at query time and combined with any naics values. Leave both industries and naics empty to include all industries.	N
`isMetric`	boolean	-	-	When true, distance values are returned in kilometres; when false, in miles. If omitted, defaults to the isMetric setting on the authenticated user's profile.	N
`isTrendAnalysis`	boolean	-	-	When true, results are returned per date range instead of aggregated across all ranges.	N
`naics`	array<integer>	-	-	Explicit raw NAICS integer codes to filter by. Combined with any industries values. Leave both naics and industries empty to include all industries.	N
`originIds`	array<string>	-	-	Encoded origin zone IDs. IDs use passThrough=false. Provide either originIds or origins, not both.	N
`origins`	array<object>	code: string; iso_3166_2: string; passThrough: string (values: false, true, only); type: string (values: Country, State, County, City, FSA, ZIP, TAZ, CTR, Custom, Segment, RelatedRoad)	-	Origin zone objects for the analysis. passThrough is optional and accepts 'false', 'true', or 'only'; omitted values default to 'false'. Provide either origins or originIds, not both.	N
`percentiles`	array<integer>	-	-	Percentile values (1–99) to calculate for journey distance and duration. Defaults to [15, 85] when omitted.	N
`tripChainCriteria`	object	maxStopDuration: integer; shortJourneyDistanceThreshold: number	-	Trip-chaining criteria. Omit or send zero values to run without trip chaining.	N
`vehicleClassIds`	array<string>	-	-	Vehicle class filter IDs from GET /api/v2/filters/vehicle-classes. IDs must use the scheme_vehicleClassIndex_categoryIndex format and share one scheme; IDs that do not name a known vehicle class are rejected. An empty array includes all vehicle classes.	N
`vehicleClassSchemeId`	integer	-	1, 2, 3, 4, 5	Vehicle classification scheme, from 1 through 5. Defaults to 2 (FHWA/GVWR) when omitted.	N
`vehicleClasses`	array<object>	vehicleType: string (values: Truck, Passenger, MPV, Bus, Limo, Other, n/a); weightClass: string (values: *, Class 1, Class 2, Class 3, Class 4, Class 5, Class 6, Class 7, Class 8, Class A, Class B, Class C, Class D, Class E, Class F, Class G, Class H)	-	Vehicle class filters. Use an empty array to include all vehicle classes.	N
`vocations`	array<integer>	-	1, 2, 3, 4, 5	Vocation IDs from GET /api/v2/filters/vocations. An empty array includes all vocations.	N
