+++++

+You must have `all` privileges for the *Synthetics* feature in the *{observability}* section of the
+<<kibana-feature-privileges,{kib} feature privileges>>.
+
+
+[[parameters-add-request-body]]
+==== Request body
+
+The request body can contain either a single parameter object or an array of parameter objects. The parameter object schema includes the following attributes:
+
+`key`::
+(Required, string) The key of the parameter.
+
+`value`::
+(Required, string) The value associated with the parameter.
+
+`description`::
+(Optional, string) A description of the parameter.
+
+`tags`::
+(Optional, array of strings) An array of tags to categorize the parameter.
+
+`share_across_spaces`::
+(Optional, boolean) Whether the parameter should be shared across spaces.
+
+When adding a single parameter, provide a single object. When adding multiple parameters, provide an array of parameter objects.
+
+[[parameters-add-example]]
+==== Example
+
+Here are examples of POST requests to add parameters, either as a single parameter or as an array of parameters:
+
+To add a single parameter:
+
+[source,sh]
+--------------------------------------------------
+POST /api/synthetics/params
+{
+  "key": "your-key-name",
+  "value": "your-parameter-value",
+  "description": "Param to use in browser monitor",
+  "tags": ["authentication", "security"],
+  "share_across_spaces": true
+}
+--------------------------------------------------
+
+To add multiple parameters:
+
+[source,sh]
+--------------------------------------------------
+POST /api/synthetics/params
+[
+  {
+    "key": "param1",
+    "value": "value1"
+  },
+  {
+    "key": "param2",
+    "value": "value2"
+  }
+]
+--------------------------------------------------
+
+The API returns a response based on the request. If you added a single parameter, it will return a single parameter object. If you added multiple parameters, it will return an array of parameter objects.
+
+[[parameters-add-response-example]]
+==== Response Example
+
+The API response includes the created parameter(s) as JSON objects, where each parameter object has the following attributes:
+
+- `id` (string): The unique identifier of the parameter.
+- `key` (string): The key of the parameter.
+- `value` (string): The value associated with the parameter.
+- `description` (string, optional): The description of the parameter.
+- `tags` (array of strings, optional): An array of tags associated with the parameter.
+- `share_across_spaces` (boolean, optional): Indicates whether the parameter is shared across spaces.
+
+Here's an example response for a single added parameter:
+
+[source,json]
+--------------------------------------------------
+{
+  "id": "unique-parameter-id",
+  "key": "your-key-name",
+  "value": "your-param-value",
+  "description": "Param to use in browser monitor",
+  "tags": ["authentication", "security"],
+  "share_across_spaces": true
+}
+--------------------------------------------------
+
+And here's an example response for adding multiple parameters:
+
+[source,json]
+--------------------------------------------------
+[
+  {
+    "id": "param1-id",
+    "key": "param1",
+    "value": "value1"
+  },
+  {
+    "id": "param2-id",
+    "key": "param2",
+    "value": "value2"
+  }
