Create An API Test With The API

Docs > Synthetic Monitoring > Synthetic Monitoring Guides > Create An API Test With The API

Overview

This guide contains examples of configuration files and links to Terraform resources you can use to create API tests, as well as associated synthetics resources such as global variables.

If you’re using the API, see the JSON configuration examples
If you’re using the Python client, see the Python client example
If you’re using Terraform, see the Terraform example

For more information, see Create an API test in the API documentation.

Terraform

API tests

The synthetic test resource, with type set to api, can be used to create and manage your API tests through Terraform.

Private locations

If you need to run your synthetic tests from custom or secured locations, you can use the private location resource to create and manage private locations to run your tests from. Learn more on the private locations page.

Global and local variables

Use the synthetics global variable resource to create and manage synthetics global variables, which are variables that can be securely shared across tests. You can also create test-specific local variables with builtins by defining the config_variable nested schema with type = "text" in your synthetic test resources.
