//! Adds a specified user to the followers of a specified channel.
//! [`create-custom-rewards`](https://dev.twitch.tv/docs/api/reference#create-custom-rewards)
//!
//! # Accessing the endpoint
//!
//! ## Request: [CreateCustomRewardRequest]
//!
//! To use this endpoint, construct a [`CreateCustomRewardRequest`] with the [`CreateCustomRewardRequest::builder()`] method.
//!
//! ```rust
//! use twitch_api2::helix::points::create_custom_rewards;
//! let request = create_custom_rewards::CreateCustomRewardRequest::builder()
//!     .broadcaster_id("274637212")
//!     .build();
//! ```
//!
//! ## Body: [CreateCustomRewardBody]
//!
//! We also need to provide a body to the request containing what we want to change.
//!
//! ```
//! # use twitch_api2::helix::points::create_custom_rewards;
//! let body = create_custom_rewards::CreateCustomRewardBody::builder()
//!     .cost(500)
//!     .title("hydrate!")
//!     .build();
//! ```
//!
//! ## Response: [CreateCustomRewardResponse]
//!
//!
//! Send the request to receive the response with [`HelixClient::req_post()`](helix::HelixClient::req_post).
//!
//!
//! ```rust, no_run
//! use twitch_api2::helix::{self, points::create_custom_rewards};
//! # 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 = create_custom_rewards::CreateCustomRewardRequest::builder()
//!     .broadcaster_id("274637212")
//!     .build();
//! let body = create_custom_rewards::CreateCustomRewardBody::builder()
//!     .cost(500)
//!     .title("hydrate!")
//!     .build();
//! let response: create_custom_rewards::CreateCustomRewardResponse = client.req_post(request, body, &token).await?.data;
//! # Ok(())
//! # }
//! ```
//!
//! You can also get the [`http::Request`] with [`request.create_request(&token, &client_id)`](helix::RequestPost::create_request)
//! and parse the [`http::Response`] with [`CreateCustomRewardRequest::parse_response(None, &request.get_uri(), response)`](CreateCustomRewardRequest::parse_response)
