+# Put mapping
+Introduced 1.0
+{: .label .label-purple }
+
+The put mapping API operation lets you add new mappings and fields to an index.
+
+## Example
+
+```json
+PUT /sample-index/_mapping
+{
+  "properties": {
+    "age": {
+      "type": "integer"
+    },
+    "occupation":{
+      "type": "text"
+    }
+  }
+}
+```
+
+
+## Path and HTTP methods
+
+```
+PUT /<target-index>/_mapping
+PUT /_mapping
+```
+
+## URL parameters
+
+All put mapping parameters are optional.
+
+Parameter | Data Type | Description
+:--- | :--- | :---
+&lt;target-index&gt; | Data Type | The index to add the mapping to. If you do not specify this parameter, OpenSearch adds the mapping to all indices within the cluster.
+allow_no_indices | Boolean | Whether to ignore wildcards that don’t match any indices. Default is `true`.
+expand_wildcards | String | Expands wildcard expressions to different indices. Combine multiple values with commas. Available values are `all` (match all indices), `open` (match open indices), `closed` (match closed indices), `hidden` (match hidden indices), and `none` (do not accept wildcard expressions), which must be used with `open`, `closed`, or both. Default is `open`.
+ignore_unavailable | Boolean | If true, OpenSearch does not include missing or closed indices in the response.
+master_timeout | Time | How long to wait for a connection to the master node. Default is `30s`.
+timeout | Time | How long to wait for the response to return. Default is `30s`.
+write_index_only | Boolean | Whether OpenSearch should add the mapping only to the write index.
+
+## Request body
+
+The request body must contain the `properties` object, which has all of the mappings that you want to add.
+
+```json
+{
+  "properties":{
+    "color":{
+      "type": "text"
+    },
+    "year":{
+      "type": "integer"
+    }
+  }
+}
+```
+
+## Response
+
+```json
+{
+    "acknowledged": true
+}
+```
