This field is deprecated. Use the restriction policies API to manage permissions. | | | description [*required*] | string | Description of the global variable. | | | id | string | Unique identifier of the global variable. | | | is_fido | boolean | Determines if the global variable is a FIDO variable. | | | is_totp | boolean | Determines if the global variable is a TOTP/MFA variable. | | | name [*required*] | string | Name of the global variable. Unique across Synthetic global variables. | | | parse_test_options | object | Parser options to use for retrieving a Synthetic global variable from a Synthetic test. Used in conjunction with `parse_test_public_id`. | | parse_test_options | field | string | When type is `http_header`, name of the header to use to extract the value. | | parse_test_options | localVariableName | string | When type is `local_variable`, name of the local variable to use to extract the value. | | parse_test_options | parser | object | Details of the parser to use for the global variable. | | parser | type [*required*] | enum | Type of parser for a Synthetic global variable from a synthetics test. Allowed enum values: `raw,json_path,regex,x_path` | | parser | value | string | Regex or JSON path used for the parser. Not used with type `raw`. | | parse_test_options | type [*required*] | enum | Type of value to extract from a test for a Synthetic global variable. Allowed enum values: `http_body,http_header,http_status_code,local_variable` | | | parse_test_public_id | string | A Synthetic test ID to use as a test to generate the variable value. | | | tags [*required*] | [string] | Tags of the global variable. | | | value [*required*] | object | Value of the global variable. | | value | options | object | Options for the Global Variable for MFA. | | options | totp_parameters | object | Parameters for the TOTP/MFA variable | | totp_parameters | digits | int32 | Number of digits for the OTP code. | | totp_parameters | refresh_interval | int32 | Interval for which to refresh the token (in seconds). | | value | secure | boolean | Determines if the value of the variable is hidden. | | value | value | string | Value of the global variable. When reading a global variable, the value will not be present if the variable is hidden with the `secure` property. | {% /tab %} {% tab title="Example" %} ```json { "attributes": { "restricted_roles": [ "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" ] }, "description": "Example description", "id": "string", "is_fido": false, "is_totp": false, "name": "MY_VARIABLE", "parse_test_options": { "field": "content-type", "localVariableName": "LOCAL_VARIABLE", "parser": { "type": "raw", "value": "string" }, "type": "http_body" }, "parse_test_public_id": "abc-def-123", "tags": [ "team:front", "test:workflow-1" ], "value": { "options": { "totp_parameters": { "digits": 6, "refresh_interval": 30 } }, "secure": false, "value": "example-value" } } ``` {% /tab %} {% /tab %} {% tab title="403" %} Forbidden {% tab title="Model" %} Error response object. | Field | Type | Description | | ------------------------ | -------- | ------------------------------------ | | errors [*required*] | [string] | Array of errors returned by the API. | {% /tab %} {% tab title="Example" %} ```json { "errors": [ "Bad Request" ] } ``` {% /tab %} {% /tab %} {% tab title="404" %} Not found {% tab title="Model" %} Error response object. | Field | Type | Description | | ------------------------ | -------- | ------------------------------------ | | errors [*required*] | [string] | Array of errors returned by the API. | {% /tab %} {% tab title="Example" %} ```json { "errors": [ "Bad Request" ] } ``` {% /tab %} {% /tab %} {% tab title="429" %} Too many requests {% tab title="Model" %} Error response object. | Field | Type | Description | | ------------------------ | -------- | ------------------------------------ | | errors [*required*] | [string] | Array of errors returned by the API. | {% /tab %} {% tab title="Example" %} ```json { "errors": [ "Bad Request" ] } ``` {% /tab %} {% /tab %} ### Code Example ##### \# Path parameters export variable_id="CHANGE_ME" \# Curl command curl -X GET "https://api.datadoghq.com/api/v1/synthetics/variables/${variable_id}" \ -H "Accept: application/json" \ -H "DD-API-KEY: ${DD_API_KEY}" \ -H "DD-APPLICATION-KEY: ${DD_APP_KEY}" ##### ```python """ Get a global variable returns "OK" response """ from datadog_api_client import ApiClient, Configuration from datadog_api_client.v1.api.synthetics_api import SyntheticsApi configuration = Configuration() with ApiClient(configuration) as api_client: api_instance = SyntheticsApi(api_client) response = api_instance.get_global_variable( variable_id="variable_id", ) print(response) ``` #### Instructions First [install the library and its dependencies](https://docs.datadoghq.com/api/latest.md?code-lang=python) and then save the example to `example.py` and run following commands: DD_SITE="datadoghq.com" DD_API_KEY="" DD_APP_KEY="" python3 "example.py" ##### ```ruby # Get a global variable returns "OK" response require "datadog_api_client" api_instance = DatadogAPIClient::V1::SyntheticsAPI.new p api_instance.get_global_variable("variable_id") ``` #### Instructions First [install the library and its dependencies](https://docs.datadoghq.com/api/latest.md?code-lang=ruby) and then save the example to `example.rb` and run following commands: DD_SITE="datadoghq.com" DD_API_KEY="" DD_APP_KEY="" rb "example.rb" ##### ```go // Get a global variable returns "OK" response package main import ( "context" "encoding/json" "fmt" "os" "github.com/DataDog/datadog-api-client-go/v2/api/datadog" "github.com/DataDog/datadog-api-client-go/v2/api/datadogV1" ) func main() { ctx := datadog.NewDefaultContext(context.Background()) configuration := datadog.NewConfiguration() apiClient := datadog.NewAPIClient(configuration) api := datadogV1.NewSyntheticsApi(apiClient) resp, r, err := api.GetGlobalVariable(ctx, "variable_id") if err != nil { fmt.Fprintf(os.Stderr, "Error when calling `SyntheticsApi.GetGlobalVariable`: %v\n", err) fmt.Fprintf(os.Stderr, "Full HTTP response: %v\n", r) } responseContent, _ := json.MarshalIndent(resp, "", " ") fmt.Fprintf(os.Stdout, "Response from `SyntheticsApi.GetGlobalVariable`:\n%s\n", responseContent) } ``` #### Instructions First [install the library and its dependencies](https://docs.datadoghq.com/api/latest.md?code-lang=go) and then save the example to `main.go` and run following commands: DD_SITE="datadoghq.com" DD_API_KEY="" DD_APP_KEY="" go run "main.go" ##### ```java // Get a global variable returns "OK" response import com.datadog.api.client.ApiClient;
