Aggregate services
POST /v1/catalog-services/aggregate
Counts the services of a product catalog with filtering and grouping by catalog section.
The dateCreate, timestampX, dateActiveFrom, and dateActiveTo fields are not accepted in filter: the request returns 400 UNKNOWN_FILTER_FIELD before calling Bitrix24. This endpoint does not support date-range filtering. Calculate aggregates for a specific period in your integration using records from the list endpoint, where these dates are available in select and responses.
Fields available for aggregation:
iblockSectionId— catalog section, forgroupBy
A service has no numeric fields whose sum or average carries meaning. The sum, avg, min, max functions accept identifier fields — id, iblockId, iblockSectionId, measure, vatId, createdBy, modifiedBy, type — and the sort order sort. The main scenario is counting services with count, including by section.
Request fields (body)
| Parameter | Type | Required | Description |
|---|---|---|---|
Parameterfilter |
Typeobject | Requiredyes | DescriptionFiltering by the fields of GET /v1/catalog-services/fields. The iblockId key is required — the product catalog ID from GET /v1/catalogs. To select the services of one section, pass iblockSectionId with an ID from GET /v1/catalog-sections.Filtering syntax |
Parameteraggregate |
Typearray | Requiredno | DescriptionAggregations: [{ "field": "sort", "function": "max" }]. Functions: sum, avg, min, max, count. For count, the field is "*". Without the parameter — count only |
ParametergroupBy |
Typestring | string[] | Requiredno | DescriptionField or array of fields to group by (up to 5). Value — iblockSectionId |

groupBy also accepts an array: "groupBy": ["iblockSectionId"], up to 5 fields.
Other scenarios
The blocks below are request bodies.
Number of services in a catalog — a body without aggregate or groupBy, the fastest request, with no records fetched. The iblockId filter is required here too:
{ "filter": { "iblockId": 25 } }
Number of services in each catalog section — services without a section are collected into a group with iblockSectionId: null:
{ "filter": { "iblockId": 25 }, "groupBy": "iblockSectionId" }
Response fields
| Field | Type | Description |
|---|---|---|
Fieldsuccess |
Typeboolean | DescriptionAlways true on success |
Fielddata.count |
Typenumber | DescriptionTotal number of services matching the filter |
Fielddata.aggregates |
Typeobject | DescriptionResults of numeric functions: { "sort": { "max": 500 } }. Without numeric functions — an empty object |
Fielddata.groups |
Typearray | DescriptionGroups — present only with groupBy. Each element: grouping fields + count + aggregates |
Fielddata.meta.totalRecords |
Typenumber | DescriptionTotal number of records |
Fielddata.meta.recordsProcessed |
Typenumber | DescriptionNumber of processed records (up to 5000). For a request without numeric functions or groupBy — 0 |
Fielddata.meta.truncated |
Typeboolean | Descriptiontrue when the numbers were computed over only some of the records that match the filter: fewer records were read than data.count promised — including when more than 5000 matched the filter — or the slice was cut short by a sub-page error. The size of the gap is reported in data.meta.recordsShortfall, the interrupted slice in data.meta.pageErrorSample. Always present, and false on a complete response. If the request has neither groupBy nor numeric functions, no records are fetched and the flag is always false |
Fielddata.meta.groupTotal |
Typenumber | DescriptionNumber of groups. Present only with groupBy |
Fielddata.meta.groupsTruncated |
Typeboolean | Descriptiontrue if the number of groups was limited. Present only with groupBy |
Response example
{
"success": true,
"data": {
"count": 2,
"aggregates": {},
"groups": [
{
"iblockSectionId": 281,
"count": 2,
"aggregates": {}
}
],
"meta": {
"totalRecords": 2,
"recordsProcessed": 2,
"truncated": false,
"groupTotal": 1,
"groupsTruncated": false
}
}
}
Without groupBy, the data.groups field is absent from the response.
Error response example
400 — a field outside the list available for grouping:
{
"success": false,
"error": {
"code": "INVALID_PARAMS",
"message": "groupBy field 'nonexistent' is not aggregatable on this entity. Available: iblockSectionId."
}
}
Errors
| HTTP | Code | Description |
|---|---|---|
| HTTP400 | CodeMISSING_REQUIRED_FILTER |
DescriptionThe required filter.iblockId filter was not passed. This is checked before calling Bitrix24. The message contains an example request body |
| HTTP400 | CodeUNKNOWN_FILTER_FIELD |
DescriptionFilter on a field that a service does not have, or on a date field: dateCreate, timestampX, dateActiveFrom, dateActiveTo. The message contains the list of available fields |
| HTTP400 | CodeINVALID_PARAMS |
DescriptionThe groupBy field is outside the available list — the message lists the allowed ones |
| HTTP400 | CodeINVALID_PARAMS |
DescriptionA numeric function over an unknown field — Field '<name>' not found. Available numeric fields: ... |
| HTTP400 | CodeINVALID_PARAMS |
DescriptionMore than 5 fields passed in groupBy |
| HTTP422 | CodeBITRIX_ERROR |
Descriptionfilter.iblockId holds the ID of an offer catalog rather than a product catalog (productType is not allowed for this catalog) |
| HTTP403 | CodeSCOPE_DENIED |
DescriptionThe API key does not have the catalog scope |
| HTTP401 | CodeMISSING_API_KEY |
DescriptionThe X-Api-Key header was not passed |
| HTTP429 | CodeRATE_LIMITED |
DescriptionRate limit exceeded: 300 requests per minute per portal. All API keys of the portal share one limit. The current limit is returned in the x-ratelimit-limit header. Retry after the delay in the Retry-After header |

Known specifics
count is resolved in one request, grouping is not. count without groupBy is computed in a single call regardless of the size of the result set. groupBy and the sum, avg, min, max functions load records page by page — up to 5000 — and compute the values on the server side. If more than 5000 records match the filter, meta.truncated is true, and the groups are built over the first 5000. The ceiling is not the only reason for this marker: it also appears when fewer records were read than data.count promised, and the size of the gap is reported in data.meta.recordsShortfall.
The truncation marker travels with the number itself. When a response arrives with meta.truncated: true, the marker truncated: true sits inside every field object in data.aggregates and on every element of data.groups, and data.meta.warnings gains a warning with the code AGGREGATE_TRUNCATED. A client that reads only the number itself therefore sees that it was computed over only some of the records. None of these markers appear on a complete response. For full details, see Aggregation POST — the 5000-record ceiling.
