Aggregate offers

POST /v1/catalog-offers/aggregate

Counts product offers and aggregates their numeric fields — sum, average, minimum and maximum — with filtering and grouping.

Fields available for aggregation:

  • purchasingPrice — purchase price, suitable for numeric aggregation
  • quantity — stock balance, suitable for numeric aggregation
  • iblockSectionId — catalog section, for groupBy

Request fields (body)

Parameter Type Required Description
filter object yes Filtering by the fields of GET /v1/catalog-offers/fields. The iblockId key is required — the offer catalog ID from GET /v1/catalogs. parentId selects the offers of one parent product; type accepts one exact value: 4 or 5.
Filtering syntax
aggregate array no Aggregations: [{ "field": "purchasingPrice", "function": "sum" }]. Functions: sum, avg, min, max, count. For count, the field is "*". Without the parameter — count only
groupBy string | string[] no Field or array of fields to group by (up to 5). Values — from the list above

To group by several fields, pass an array: "groupBy": ["iblockSectionId", "quantity"], up to 5 fields.

Other scenarios

The blocks below are request bodies.

Number of offers in a catalog — a body without aggregate, the fastest request, with no records fetched. The iblockId filter is required here too:

JSON 
{ "filter": { "iblockId": 27 } }

Response fields

Field Type Description
success boolean Always true on success
data.count number Total number of offers matching the filter
data.aggregates object Aggregation results: { "purchasingPrice": { "sum": 0, "avg": 0 } }. Without numeric functions — an empty object
data.groups array Groups — present only with groupBy. Each element: grouping fields + count + aggregates
data.meta.totalRecords number Total number of records
data.meta.recordsProcessed number Number of processed records (up to 5000). For a request without numeric functions or groupBy — 0
data.meta.truncated boolean true 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 a numeric function, no records are fetched and the flag is always false
data.meta.groupTotal number Number of groups. Present only with groupBy
data.meta.groupsTruncated boolean true if the number of groups was limited. Present only with groupBy

Response example

JSON 
{
  "success": true,
  "data": {
    "count": 2,
    "aggregates": {
      "purchasingPrice": { "sum": 940, "avg": 470 }
    },
    "groups": [
      {
        "iblockSectionId": null,
        "count": 2,
        "aggregates": { "purchasingPrice": { "sum": 940, "avg": 470 } }
      }
    ],
    "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 aggregation:

JSON 
{
  "success": false,
  "error": {
    "code": "INVALID_PARAMS",
    "message": "groupBy field 'nonexistent' is not aggregatable on this entity. Available: purchasingPrice, quantity, iblockSectionId."
  }
}

Errors

HTTP Code Description
400 MISSING_REQUIRED_FILTER The required filter filter.iblockId was not passed — checked before the Bitrix24 call; the message contains an example body
400 UNSUPPORTED_FILTER filter.type received a value other than 4 and 5, an array, or an operator
400 INVALID_PARAMS The groupBy field is outside the available list — the message lists the allowed ones
400 INVALID_PARAMS A numeric function over an unknown field — Field '<name>' not found. Available numeric fields: ...
400 INVALID_PARAMS More than 5 fields passed in groupBy
403 SCOPE_DENIED The API key does not have the catalog scope
401 MISSING_API_KEY The X-Api-Key header was not passed
429 RATE_LIMITED Rate limit exceeded: 300 requests per minute per portal, all API keys of the portal share one limit. The exact value arrives in the x-ratelimit-limit header (the cap is divided across replicas). Retry after the delay in the Retry-After header

Known specifics

count is resolved in one request, numeric functions are not. count is computed in a single call regardless of the size of the result set. The sum, avg, min, max functions and groupBy 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 aggregates and 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. Full details — Aggregation POST — the 5000-record ceiling.
