# Bulk Create Watches

> Create up to 100 watches in a single call

## Overview

Bulk-create variant of [Create Watch](/api-reference/monitoring/watches/create).
The full set is validated upfront — no partial inserts. Counts against the
per-plan `watches.maxResources` quota.

## Body Parameters

<ParamField body="watches" type="object[]" required>
  1--100 watch specifications. Each item has the same shape as the
  body of [Create Watch](/api-reference/monitoring/watches/create).
</ParamField>

## Response

<ResponseField name="object" type="string">Always `"list"`.</ResponseField>
<ResponseField name="data" type="object[]">Array of created `Watch` objects in input order.</ResponseField>
<ResponseField name="request_id" type="string">Request identifier.</ResponseField>

## Errors

* **400** — any item fails validation (whole batch rejected).
* **409** — quota exceeded.
* **413** — combined payload exceeds the per-request limit.

<Note>
  Filter keys inside `query.filters` are **camelCase** (`niceClasses`,
  `jurisdictions`, `ownerId`, ...). Unknown keys -- including snake\_case
  typos like `nice_classes` -- are rejected with `400`, as is `query.match`
  in any form. See [the canonical query
  reference](/guides/monitoring/watches#the-query-dsl).
