Authentication

Method

The GraphQL API does not expose a separate count field. To count records for a period, run the cdrRecords query described in Get CDR Records with the maximum page size and follow paginationInfo.nextCursor until it is null, summing the length of cdrs on each page. For very large periods, generate the exportLink instead and count the rows of the CSV.

query($type: CdrType!, $startDatetime: DateTime!, $endDatetime: DateTime!, $limit: Int, $cursor: String) {
  cdrRecords(type: $type, startDatetime: $startDatetime, endDatetime: $endDatetime, limit: $limit, cursor: $cursor) {
    paginationInfo {
      limit
      nextCursor
    }
    cdrs {
      __typename
    }
  }
}

{
  "type": "SMS",
  "startDatetime": "2026-09-01T00:00:00.000Z",
  "endDatetime": "2026-09-02T00:00:00.000Z",
  "limit": 1000
}
