`PATCH /api/v3/study:batch-update`

## Request

- Base URL: `https://{tenant_name}.benchling.com`
- URL: `https://{tenant_name}.benchling.com/api/v3/study:batch-update`
- Auth: HTTP bearer

Batch update Study synchronously in one transaction. Maximum 25 items per request.

## Request body

- object
  - `items` UpdateStudyInputWithPathParams[], required
    - `archiveReason` string: Why it is being archived. Required when `archived` is `true`, and not allowed when unarchiving.
    - `archived` boolean: Set to `true` to archive or `false` to unarchive it. Archiving requires `archiveReason`.
    - `authorIds` string[]: The IDs of the users or apps to set as study authors. Omit to leave authors unchanged. Pass an empty array to clear all authors.
    - `description` string: The description of the study. Omit to leave unchanged. Max 2048 characters.
    - `designEntry` CreateStudyDesignEntryInput
      - `folderId` string, required
      - `initialDay` string
      - `name` string, required
      - `schemaFields` object
      - `schemaId` string: The ID of the schema to associate with this object.
      - `templateId` string
    - `designEntryId` string, nullable: The ID of an entry to use as the study design entry. Omit to leave unchanged. Pass null to remove the design entry. Only supported for custom studies. On a custom study in EXECUTION under a schema that requires design approval, this cannot be changed unless the update also moves the study into the DESIGN phase.
    - `displayId` string: The ID to assign to the study. Only allowed when the study schema is configured for manual ID assignment (i.e., `idGenerationMode` is `MANUAL`). Must be unique within the tenant.
    - `fieldValues` UpdateFieldValueInput[]: Use schemaFields instead.
      - `fieldDefinitionId` string, required
      - `value` unknown, required
    - `folderId` string: The ID of the folder to move the study to. Omit to leave unchanged.
    - `id` string, required
    - `name` string: The name of the study. Omit to leave unchanged.
    - `phase` 'DESIGN' | 'EXECUTION' | 'COMPLETE': The lifecycle phase of the study. Omit to leave unchanged. See the endpoint description for transition rules.
    - `schemaFields` object
