lib.rs

//! A fully generated, opinionated API client library for Zoom.
//!
//! [![docs.rs](https://docs.rs/zoom-api/badge.svg)](https://docs.rs/zoom-api)
//!
//! ## API Details
//!
//! The Zoom API allows developers to access information from Zoom. You can use this API to build private services or public applications on the [Zoom App Marketplace](http://marketplace.zoom.us). To learn how to get your credentials and create private/public applications, read our [Authorization Guide](https://marketplace.zoom.us/docs/guides/authorization/credentials).
//! All endpoints are available via `https` and are located at `api.zoom.us/v2/`.
//!
//! For instance you can list all users on an account via `https://api.zoom.us/v2/users/`.
//!
//! [API Terms of Service](https://zoom.us/docs/en-us/zoom_api_license_and_tou.html)

//!
//! ## Client Details
//!
//! This client is generated from the [Zoom OpenAPI
//! specs](https://marketplace.zoom.us/docs/api-reference/zoom-api/Zoom%20API.oas2.json) based on API spec version `2.0.0`. This way it will remain
//! up to date as features are added. The documentation for the crate is generated
//! along with the code to make this library easy to use.
//!
//!
//! To install the library, add the following to your `Cargo.toml` file.
//!
//! ```toml
//! [dependencies]
//! zoom-api = "0.7.0"
//! ```
//!
//! ## Basic example
//!
//! Typical use will require intializing a `Client`. This requires
//! a user agent string and set of credentials.
//!
//! ```rust
//! use zoom_api::Client;
//!
//! let zoom = Client::new(
//!     String::from("client-id"),
//!     String::from("client-secret"),
//!     String::from("redirect-uri"),
//!     String::from("token"),
//!     String::from("refresh-token")
//! );
//! ```
//!
//! Alternatively, the library can search for most of the variables required for
//! the client in the environment:
//!
//! - `ZOOM_CLIENT_ID`
//! - `ZOOM_CLIENT_SECRET`
//! - `ZOOM_REDIRECT_URI`
//!
//! And then you can create a client from the environment.
//!
//! ```rust
//! use zoom_api::Client;
//!
//! let zoom = Client::new_from_env(
//!     String::from("token"),
//!     String::from("refresh-token")
//! );
//! ```
//!
//! It is okay to pass empty values for `token` and `refresh_token`. In
//! the initial state of the client, you will not know these values.
//!
//! To start off a fresh client and get a `token` and `refresh_token`, use the following.
//!
//! ```rust
//! use zoom_api::Client;
//!
//! async fn do_call() {
//!     let mut zoom = Client::new_from_env("", "");
//!
//!     // Get the URL to request consent from the user.
//!     // You can optionally pass in scopes. If none are provided, then the
//!     // resulting URL will not have any scopes.
//!     let user_consent_url = zoom.user_consent_url(&["some-scope".to_string()]);
//!
//!     // In your redirect URL capture the code sent and our state.
//!     // Send it along to the request for the token.
//!     let code = "thing-from-redirect-url";
//!     let state = "state-from-redirect-url";
//!     let mut access_token = zoom.get_access_token(code, state).await.unwrap();
//!
//!     // You can additionally refresh the access token with the following.
//!     // You must have a refresh token to be able to call this function.
//!     access_token = zoom.refresh_access_token().await.unwrap();
//! }
//! ```
