Elasticsearch APIs use key-based authentication. You must create an API key and use the encoded value in the request header. For example:
curl -X GET "${ES_URL}/_cat/indices?v=true" \
-H "Authorization: ApiKey ${API_KEY}"
For more information about where to find API keys for the Elasticsearch endpoint (${ES_URL}) for a project, go to Get started with Elasticsearch Serverless.
The compact and aligned text (CAT) APIs aim are intended only for human consumption using the Kibana console or command line. They are not intended for use by applications. For application consumption, it's recommend to use a corresponding JSON API.
All the cat commands accept a query string parameter help to see all the headers and info they provide, and the /_cat command alone lists all the available commands.
Get the cluster's index aliases, including filter and routing information. This API does not return data stream aliases.
IMPORTANT: CAT APIs are only intended for human consumption using the command line or the Kibana console. They are not intended for use by applications. For application consumption, use the aliases API.
A comma-separated list of aliases to retrieve. Supports wildcards (*). To retrieve all aliases, omit this parameter or use * or _all.
List of columns to appear in the response. Supports simple wildcards.
List of columns that determine how the table should be sorted.
Sorting defaults to ascending and can be changed by setting :asc
or :desc as a suffix to the column name.
The type of index that wildcard patterns can match.
If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams.
It supports comma-separated values, such as open,hidden.
Supported values include:
all: Match any data stream or index, including hidden ones.open: Match open, non-hidden indices. Also matches any non-hidden data stream.closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.none: Wildcard expressions are not accepted.Values are all, open, closed, hidden, or none.
The period to wait for a connection to the master node.
If the master node is not available before the timeout expires, the request fails and returns an error.
To indicated that the request should never timeout, you can set it to -1.
Values are -1 or 0.

]The connector and sync jobs APIs provide a convenient way to create and manage Elastic connectors and sync jobs in an internal index.
Connectors are Elasticsearch integrations for syncing content from third-party data sources, which can be deployed on Elastic Cloud or hosted on your own infrastructure.
This API provides an alternative to relying solely on Kibana UI for connector and sync job management. The API comes with a set of validations and assertions to ensure that the state representation in the internal index remains valid.
This API requires the manage_connector privilege or, for read-only endpoints, the monitor_connector privilege.
Activates the valid draft filtering for a connector.

An index template can be composed of multiple component templates.
To use a component template, specify it in an index template’s composed_of list.
Component templates are only applied to new data streams and indices as part of a matching index template.
Settings and mappings specified directly in the index template or the create index request override any settings or mappings specified in a component template.
Component templates are only used during index creation. For data streams, this includes data stream creation and the creation of a stream’s backing indices. Changes to component templates do not affect existing indices, including a stream’s backing indices.
You can use C-style /* *\/ block comments in component templates.
You can include comments anywhere in the request body except before the opening curly bracket.
Applying component templates
You cannot directly apply a component template to a data stream or index.
To be applied, a component template must be included in an index template's composed_of list.
Name of the component template to create.
Elasticsearch includes the following built-in component templates: logs-mappings; logs-settings; metrics-mappings; metrics-settings;synthetics-mapping; synthetics-settings.
Elastic Agent uses these templates to configure backing indices for its data streams.
If you use Elastic Agent and want to overwrite one of these templates, set the version for your replacement template higher than the current version.
If you don’t use Elastic Agent and want to disable all built-in component and index templates, set stack.templates.enabled to false using the cluster update settings API.
If true, this request cannot replace or update existing component templates.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.

}The analyze API performs analysis on a text string and returns the resulting tokens.
Generating excessive amount of tokens may cause a node to run out of memory.
The index.analyze.max_token_count setting enables you to limit the number of tokens that can be produced.
If more than this limit of tokens gets generated, an error occurs.
The _analyze endpoint without a specified index will always use 10000 as its limit.

}You can use the create index API to add a new index to an Elasticsearch cluster. When creating an index, you can specify the following:
Wait for active shards
By default, index creation will only return a response to the client when the primary copies of each shard have been started, or the request times out.
The index creation response will indicate what happened.
For example, acknowledged indicates whether the index was successfully created in the cluster, while shards_acknowledged indicates whether the requisite number of shard copies were started for each shard in the index before timing out.
Note that it is still possible for either acknowledged or shards_acknowledged to be false, but for the index creation to be successful.
These values simply indicate whether the operation completed before the timeout.
If acknowledged is false, the request timed out before the cluster state was updated with the newly created index, but it probably will be created sometime soon.
If shards_acknowledged is false, then the request timed out before the requisite number of shards were started (by default just the primaries), even if the cluster state was successfully updated to reflect the newly created index (that is to say, acknowledged is true).
You can change the default of only waiting for the primary shards to start through the index setting index.write.wait_for_active_shards.
Note that changing this setting will also affect the wait_for_active_shards value on all subsequent write operations.
Name of the index you wish to create. Index names must meet the following criteria:

}Deleting an index deletes its documents, shards, and metadata. It does not delete related Kibana components, such as data views, visualizations, or dashboards.

--header "Authorization: $API_KEY"Index templates define settings, mappings, and aliases that can be applied automatically to new indices.
Elasticsearch applies templates to new indices based on an wildcard pattern that matches the index name. Index templates are applied during data stream or index creation. For data streams, these settings and mappings are applied when the stream's backing indices are created. Settings and mappings specified in a create index API request override any settings or mappings specified in an index template. Changes to index templates do not affect existing indices, including the existing backing indices of a data stream.
You can use C-style /* *\/ block comments in index templates.
You can include comments anywhere in the request body, except before the opening curly bracket.
Multiple matching templates
If multiple index templates match the name of a new index or data stream, the template with the highest priority is used.
Multiple templates with overlapping index patterns at the same priority are not allowed and an error will be thrown when attempting to create a template matching an existing index template at identical priorities.
Composing aliases, mappings, and settings
When multiple component templates are specified in the composed_of field for an index template, they are merged in the order specified, meaning that later component templates override earlier component templates.
Any mappings, settings, or aliases from the parent index template are merged in next.
Finally, any configuration on the index request itself is merged.
Mapping definitions are merged recursively, which means that later mapping components can introduce new field mappings and update the mapping configuration.
If a field mapping is already contained in an earlier component, its definition will be completely overwritten by the later one.
This recursive merging strategy applies not only to field mappings, but also root options like dynamic_templates and meta.
If an earlier component contains a dynamic_templates block, then by default new dynamic_templates entries are appended onto the end.
If an entry already exists with the same key, then it is overwritten by the new definition.
Index or template name
If true, this request cannot replace or update existing index templates.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
Values are -1 or 0.
User defined reason for creating/updating the index template
An ordered list of component template names. Component templates are merged in the order specified, meaning that the last component template specified has the highest precedence.
Priority to determine index template precedence when a new data stream or index is created. The index template with the highest priority is chosen. If no priority is specified the template is treated as though it is of priority 0 (lowest priority). This number is not automatically generated by Elasticsearch.
This setting overrides the value of the action.auto_create_index cluster setting.
If set to true in a template, then indices can be automatically created using that template even if auto-creation of indices is disabled via actions.auto_create_index.
If set to false, then indices or data streams matching the template must always be explicitly created, and may never be automatically created.
The configuration option ignore_missing_component_templates can be used when an index template references a component template that might not exist
Marks this index template as deprecated. When creating or updating a non-deprecated index template that uses deprecated components, Elasticsearch will emit a deprecation warning.

}Index templates define settings, mappings, and aliases that can be applied automatically to new indices.
Elasticsearch applies templates to new indices based on an wildcard pattern that matches the index name. Index templates are applied during data stream or index creation. For data streams, these settings and mappings are applied when the stream's backing indices are created. Settings and mappings specified in a create index API request override any settings or mappings specified in an index template. Changes to index templates do not affect existing indices, including the existing backing indices of a data stream.
You can use C-style /* *\/ block comments in index templates.
You can include comments anywhere in the request body, except before the opening curly bracket.
Multiple matching templates
If multiple index templates match the name of a new index or data stream, the template with the highest priority is used.
Multiple templates with overlapping index patterns at the same priority are not allowed and an error will be thrown when attempting to create a template matching an existing index template at identical priorities.
Composing aliases, mappings, and settings
When multiple component templates are specified in the composed_of field for an index template, they are merged in the order specified, meaning that later component templates override earlier component templates.
Any mappings, settings, or aliases from the parent index template are merged in next.
Finally, any configuration on the index request itself is merged.
Mapping definitions are merged recursively, which means that later mapping components can introduce new field mappings and update the mapping configuration.
If a field mapping is already contained in an earlier component, its definition will be completely overwritten by the later one.
This recursive merging strategy applies not only to field mappings, but also root options like dynamic_templates and meta.
If an earlier component contains a dynamic_templates block, then by default new dynamic_templates entries are appended onto the end.
If an entry already exists with the same key, then it is overwritten by the new definition.
Index or template name
If true, this request cannot replace or update existing index templates.
Period to wait for a connection to the master node. If no response is received before the timeout expires, the request fails and returns an error.
Values are -1 or 0.
User defined reason for creating/updating the index template
An ordered list of component template names. Component templates are merged in the order specified, meaning that the last component template specified has the highest precedence.
Priority to determine index template precedence when a new data stream or index is created. The index template with the highest priority is chosen. If no priority is specified the template is treated as though it is of priority 0 (lowest priority). This number is not automatically generated by Elasticsearch.
This setting overrides the value of the action.auto_create_index cluster setting.
If set to true in a template, then indices can be automatically created using that template even if auto-creation of indices is disabled via actions.auto_create_index.
If set to false, then indices or data streams matching the template must always be explicitly created, and may never be automatically created.
The configuration option ignore_missing_component_templates can be used when an index template references a component template that might not exist
Marks this index template as deprecated. When creating or updating a non-deprecated index template that uses deprecated components, Elasticsearch will emit a deprecation warning.

--header "Authorization: $API_KEY"Add new fields to an existing data stream or index. You can also use this API to change the search settings of existing fields and add new properties to existing object fields. For data streams, these changes are applied to all backing indices by default.
Add multi-fields to an existing field
Multi-fields let you index the same field in different ways. You can use this API to update the fields mapping parameter and enable multi-fields for an existing field. WARNING: If an index (or data stream) contains documents when you add a multi-field, those documents will not have values for the new multi-field. You can populate the new multi-field with the update by query API.
Change supported mapping parameters for an existing field
The documentation for each mapping parameter indicates whether you can update it for an existing field using this API.
For example, you can use the update mapping API to update the ignore_above parameter.
Change the mapping of an existing field
Except for supported mapping parameters, you can't change the mapping or field type of an existing field. Changing an existing field could invalidate data that's already indexed.
If you need to change the mapping of a field in a data stream's backing indices, refer to documentation about modifying data streams. If you need to change the mapping of a field in other indices, create a new index with the correct mapping and reindex your data into that index.
Rename a field
Renaming a field would invalidate data already indexed under the old field name. Instead, add an alias field to create an alternate field name.
A comma-separated list of index names the mapping should be added to (supports wildcards); use _all or omit to add the mapping on all indices.
If false, the request returns an error if any wildcard expression, index alias, or _all value targets only missing or closed indices.
