Aggregate basket items

POST /v1/basket-items/aggregate

Counts items and computes numeric aggregations (sum, avg, min, max) over the price and quantity fields. Supports filtering and grouping by orderId, productId, currency.

Standard fields

Field Purpose
price Numeric — suitable for sum / avg / min / max (aggregations over the unit price)
quantity Numeric — suitable for sum / avg / min / max (aggregations over quantity)
currency Categorical — used in groupBy (by currency)
orderId, productId Identifiers — used in groupBy (by order or product)

The full list of aggregatable fields is shown in the table above.

Request fields (body)

Parameter Type Required Description
aggregate array no Array of aggregations: [{ "field": "quantity", "function": "sum" }]. Functions: count, sum, avg, min, max. For count, the field is "*". Without the parameter — count only
filter object no Filtering — the same fields as in GET /v1/basket-items. Filtering syntax
groupBy string | string[] no A field or array of fields to group by (maximum 5)
groupOrderBy array no Group sorting: [{ "field": "quantity:sum", "direction": "desc" }]
groupLimit number no Limit on the number of returned groups (1-1000)

Other scenarios

Count records — count with field "*", the fastest request without fetching records. Without the aggregate array the result is the same:

JSON 
{ "aggregate": [{ "field": "*", "function": "count" }] }

Total value of all items in an order:

JSON 
{
  "aggregate": [{ "field": "price", "function": "sum" }],
  "filter": { "orderId": 33 }
}

Top 3 products by total sales:

JSON 
{
  "aggregate": [{ "field": "quantity", "function": "sum" }],
  "groupBy": "productId",
  "groupOrderBy": [{ "field": "quantity:sum", "direction": "desc" }],
  "groupLimit": 3
}

Response fields

Field Type Description
success boolean Always true on success
data.count number Total number of items matching the filter
data.aggregates object Aggregation results: { "quantity": { "sum": ... }, "price": { "avg": ... } }
data.groups array Groups (only with groupBy)
data.meta.totalRecords number Total number of records
data.meta.recordsProcessed number Number of processed records (up to 5000)
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 before groupLimit
data.meta.groupsTruncated boolean Whether the group list was truncated by groupLimit

Response example

JSON 
{
  "success": true,
  "data": {
    "count": 261,
    "aggregates": {
      "quantity": { "sum": 412 }
    },
    "groups": [
      {
        "productId": 119,
        "count": 23,
        "aggregates": { "quantity": { "sum": 47 } }
      },
      {
        "productId": 245,
        "count": 18,
        "aggregates": { "quantity": { "sum": 36 } }
      },
      {
        "productId": 87,
        "count": 14,
        "aggregates": { "quantity": { "sum": 21 } }
      }
    ],
    "meta": {
      "totalRecords": 261,
      "recordsProcessed": 261,
      "truncated": false,
      "groupTotal": 89,
      "groupsTruncated": true
    }
  }
}

Without groupBy, the data.groups field is absent from the response.

Error response example

400 — a field in groupBy does not support aggregation:

JSON 
{
  "success": false,
  "error": {
    "code": "INVALID_PARAMS",
    "message": "groupBy field 'foo' is not aggregatable on this entity. Available: price, quantity, currency, orderId, productId."
  }
}

Errors

HTTP Code Description
400 INVALID_PARAMS Unknown aggregation function
400 INVALID_PARAMS Non-existent numeric field in aggregate[].field — message Field 'foo' not found. Available numeric fields: …
400 INVALID_PARAMS A field in groupBy does not support aggregation — the message contains the list of allowed fields
400 INVALID_PARAMS More than 5 fields passed in groupBy
400 INVALID_PARAMS Reserved keywords in groupBy: count, aggregates, meta, groups
403 SCOPE_DENIED The API key lacks the sale scope
401 TOKEN_MISSING The API key has no configured tokens
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 versus numeric functions. count is computed in a single request to Bitrix24 — records are not fetched and the response returns quickly at any volume. sum / avg / min / max fetch records page by page (up to 5000) and compute on the Vibecode side. With more than 5000 records, meta.truncated will be true. 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.

Including unfinished baskets. The result set also includes items with orderId: null (products in unfinished baskets). To exclude them, add filter[orderId][!]=null.

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.
