# Cloud Tool Results API . projects . histories . executions . steps . perfSampleSeries . samples

## Instance Methods

Creates a batch of PerfSamples - a client can submit multiple batches of Perf Samples through repeated calls to this method in order to split up a large request payload - duplicates and existing timestamp entries will be ignored. - the batch operation may partially succeed - the set of elements successfully inserted is returned in the response (omits items which already existed in the database).

Lists the Performance Samples of a given Sample Series - The list results are sorted by timestamps ascending - The default page size is 500 samples; and maximum size allowed 5000 - The response token indicates the last returned PerfSample timestamp - When the results size exceeds the page size, submit a subsequent request including the page token to return the rest of the samples up to the page limit

Retrieves the next page of results.

### Method Details

`batchCreate(projectId, historyId, executionId, stepId, sampleSeriesId, body)`

    Creates a batch of PerfSamples - a client can submit multiple batches of Perf Samples through repeated calls to this method in order to split up a large request payload - duplicates and existing timestamp entries will be ignored. - the batch operation may partially succeed - the set of elements successfully inserted is returned in the response (omits items which already existed in the database).

    May return any of the following canonical error codes: - NOT_FOUND - The containing PerfSampleSeries does not exist

    Args:
      projectId: string, The cloud project (required)
      historyId: string, A tool results history ID. (required)
      executionId: string, A tool results execution ID. (required)

      body: object, The request body. (required)
        The object takes the form of:
