//! Gets the broadcaster’s list of active goals. Use this to get the current progress of each goal.
//! [`get-creator-goals`](https://dev.twitch.tv/docs/api/reference#get-creator-goals)
//!
//! # Accessing the endpoint
//!
//! ## Request: [GetCreatorGoalsRequest]
//!
//! To use this endpoint, construct a [`GetCreatorGoalsRequest`] with the [`GetCreatorGoalsRequest::builder()`] method.
//!
//! ```rust
//! use twitch_api2::helix::goals::get_creator_goals;
//! let request = get_creator_goals::GetCreatorGoalsRequest::builder()
//!     .broadcaster_id("4321".to_string())
//!     .build();
//! ```
//!
//! ## Response: [CreatorGoal](types::TwitchCategory)
//!
//! Send the request to receive the response with [`HelixClient::req_get()`](helix::HelixClient::req_get).
//!
//! ```rust, no_run
//! use twitch_api2::helix::{self, goals::get_creator_goals};
//! # use twitch_api2::client;
//! # #[tokio::main]
//! # async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync + 'static>> {
//! # let client: helix::HelixClient<'static, client::DummyHttpClient> = helix::HelixClient::default();
//! # let token = twitch_oauth2::AccessToken::new("validtoken".to_string());
//! # let token = twitch_oauth2::UserToken::from_existing(&client, token, None, None).await?;
//! let request = get_creator_goals::GetCreatorGoalsRequest::builder()
//!     .broadcaster_id("4321".to_string())
//!     .build();
//! let response: Vec<get_creator_goals::CreatorGoal> = client.req_get(request, &token).await?.data;
//! # Ok(())
//! # }
//! ```
//!
//! You can also get the [`http::Request`] with [`request.create_request(&token, &client_id)`](helix::RequestGet::create_request)
//! and parse the [`http::Response`] with [`GetCreatorGoalsRequest::parse_response(None, &request.get_uri(), response)`](GetCreatorGoalsRequest::parse_response)
