The request URL is a string representing the URL of the request. The URL syntax for the Customer API looks like:

`https://[hostname][api version][customer/core][object][parameter(s)]`

Where:

- `Hostname` is the URL for the Flow application. This looks like `<workspace>.appfireflow.com` where `<workspace>`is unique for each customer workspace. Find this workspace identifier in the URL you use to access Flow.
- `API version` refers to the version of the API being accessed. For all Customer API endpoints, this should be `v3`.
- `/customer/core` is always the same.
- `Object` is the resource in the Flow API from which you want to extract data. Examples are **users**, **commits**, and **targets**. See our [API references](https://appfire.atlassian.net/wiki/spaces/FD/pages/1802600473) for the complete list.
- `Parameter(s)` are the filters you use to extract a specific result, such as an Id, or a query parameter to restrict the result to a specific set of data. Parameter passing follows the widely used **?key=value&pattern**.

> ℹ️ API endpoints for the Flow metrics APIs follow slightly different syntax patterns. Refer to the [API references](https://appfire.atlassian.net/wiki/spaces/FD/pages/1802600473) for each endpoint for more details.
