# Batch indexing operations on one index
> Adds, updates, or deletes records in one index with a single API request.
Batching index updates reduces latency and increases data integrity.
* Actions are applied in the order they're specified.
* Actions are equivalent to the individual API requests of the same name.
This operation is subject to [indexing rate limits](https://support.algolia.com/hc/articles/4406975251089-Is-there-a-rate-limit-for-indexing-on-Algolia).
**Required ACL:** `addObject`

The Algolia Search API lets you search, configure, and manage your indices
and records
description: >
## Client libraries
Use Algolia's API clients and libraries to reliably integrate Algolia's APIs
with your apps.
The official API clients are covered by Algolia's [Service Level
Agreement](https://www.algolia.com/policies/sla).
For more information, see [Algolia's
ecosystem](https://www.algolia.com/doc/libraries).
## Base URLs
Base URLs for the Search API:
- `https://{APPLICATION_ID}.algolia.net`
- `https://{APPLICATION_ID}-dsn.algolia.net`.
If your subscription includes a [Distributed Search Network](https://dashboard.algolia.com/infra),
this ensures that requests are sent to servers closest to users.
Both URLs provide high availability by distributing requests with load
balancing.
**All requests must use HTTPS.**
## Retry strategy
To guarantee high availability, implement a retry strategy for all API
requests using the URLs of your servers as fallbacks:
- `https://{APPLICATION_ID}-1.algolianet.com`
- `https://{APPLICATION_ID}-2.algolianet.com`
- `https://{APPLICATION_ID}-3.algolianet.com`
These URLs use a different DNS provider than the primary URLs.
Randomize this list to ensure an even load across the three servers.
All Algolia API clients implement this retry strategy.
## Authentication
Add these headers to authenticate requests:
- `x-algolia-application-id`. Your Algolia application ID.
- `x-algolia-api-key`. An API key with the necessary permissions to make the
request.
The required access control list (ACL) to make a request is listed in each endpoint's reference.
You can find your application ID and API key in the [Algolia
dashboard](https://dashboard.algolia.com/account/api-keys).
## Request format
Depending on the endpoint, request bodies are either JSON objects or arrays
of JSON objects.
## Parameters
Parameters are passed as query parameters for GET and DELETE requests,
and in the request body for POST and PUT requests.
Query parameters must be
[URL-encoded](https://developer.mozilla.org/en-US/docs/Glossary/Percent-encoding).
Non-ASCII characters must be UTF-8 encoded.
Plus characters (`+`) are interpreted as spaces.
Arrays as query parameters must be one of:
- A comma-separated string: `attributesToRetrieve=title,description`
- A URL-encoded JSON array:
`attributesToRetrieve=%5B%22title%22,%22description%22%D`
## Response status and errors
The Search API returns JSON responses.
Since JSON doesn't guarantee any specific ordering, don't rely on the order
of attributes in the API response.
Successful responses return `2xx` statuses. Client errors return `4xx`
statuses. Server errors return `5xx` statuses.
Error responses have a `message` property with more information.
## Version
The current version of the Search API is version 1, indicated by the `/1/`
in each endpoint's URL.

Manage your indices and index settings.
Indices are copies of your data that are stored on Algolia's servers.
They're optimal data structures for fast search and are made up of records
and settings.

- name: Records
description: >
Add, update, and delete records from your indices.
Records are individual items in your index.
When they match a search query, they're returned as search results, in the
order determined by your ranking.
Records are schemaless JSON objects.
When adding or updating many records, check the [indexing rate
limits](https://support.algolia.com/hc/articles/4406975251089-Is-there-a-rate-limit-for-indexing-on-Algolia).

Rules are _if-then_ statements that you can use to curate search results.
Rules have _conditions_ that can trigger _consequences_.
Consequences are changes to the search results, such as changing the order
of search results or boosting a facet.
This can be useful for tuning specific queries or for merchandising.

Which indexing operation to perform:
- `addObject`: adds records to an index.
Equivalent to the "Add a new record (with auto-generated object ID)" operation.
- `updateObject`: adds or replaces records in an index.
Equivalent to the "Add or replace a record" operation.
- `partialUpdateObject`: adds or updates attributes within records.
Equivalent to the "Add or update attributes" operation with the `createIfNoExists` parameter set to true.
(If a record with the specified `objectID` doesn't exist in the specified index, this action creates adds the record to the index)
- `partialUpdateObjectNoCreate`: same as `partialUpdateObject`, but with
`createIfNoExists` set to false.
(A record isn't added to the index if its `objectID` doesn't exist)
- `deleteObject`: delete records from an index.
Equivalent to the "Delete a record" operation.
- `delete`. Delete an index. Equivalent to the "Delete an index"
operation.
- `clear`: delete all records from an index. Equivalent to the "Delete
all records from an index operation".
