//! Adds a word or phrase to the broadcaster’s list of blocked terms. These are the terms that broadcasters don’t want used in their chat room.
//! [`add-blocked-term`](https://dev.twitch.tv/docs/api/reference#add-blocked-term)
//!
//! # Accessing the endpoint
//!
//! ## Request: [AddBlockedTermRequest]
//!
//! To use this endpoint, construct a [`AddBlockedTermRequest`] with the [`AddBlockedTermRequest::builder()`] method.
//!
//! ```rust
//! use twitch_api2::helix::moderation::add_blocked_term;
//! let request = add_blocked_term::AddBlockedTermRequest::builder()
//!     .broadcaster_id("1234")
//!     .moderator_id("5678")
//!     .build();
//! ```
//!
//! ## Body: [AddBlockedTermBody]
//!
//! We also need to provide a body to the request containing what we want to change.
//!
//! ```
//! # use twitch_api2::helix::moderation::add_blocked_term;
//! let body = add_blocked_term::AddBlockedTermBody::new("A phrase I'm not fond of".to_string());
//! ```
//!
//! ## Response: [BlockedTerm]
//!
//!
//! Send the request to receive the response with [`HelixClient::req_post()`](helix::HelixClient::req_post).
//!
//!
//! ```rust, no_run
//! use twitch_api2::helix::{self, moderation::add_blocked_term};
//! # 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 = add_blocked_term::AddBlockedTermRequest::builder()
//!     .broadcaster_id("1234")
//!     .moderator_id("5678")
//!     .build();
//! let body = add_blocked_term::AddBlockedTermBody::new("A phrase I'm not fond of".to_string());
//! let response: &helix::moderation::BlockedTerm = client.req_post(request, body, &token).await?.data.first().unwrap();
//! # 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 [`AddBlockedTermRequest::parse_response(None, &request.get_uri(), response)`](AddBlockedTermRequest::parse_response)
