Stytch Rust Library

The Stytch Rust library makes it easy to use the Stytch user infrastructure API in server-side Rust applications.

It pairs well with the Stytch Web SDK or your own custom authentication flow.

The minimum supported Rust version (MSRV) of this library is Rust 1.70.


Use cargo add stytch to add this to your Cargo.toml:

stytch = "2.0.0"


You can find your API credentials in the Stytch Dashboard.

This client library supports all of Stytch's live products:




Example B2C usage

Create an API client:

let client = stytch::consumer::client::Client::new(

Send a magic link by email:

use stytch::consumer::magic_links_email::LoginOrCreateRequest;

let resp = client.magic_links.email.login_or_create(LoginOrCreateRequest{
    email: String::from("sandbox@stytch.com"),
    login_magic_link_url: Some(String::from("https://example.com/authenticate")),
    signup_magic_link_url: Some(String::from("https://example.com/authenticate")),

Authenticate the token from the magic link:

use stytch::consumer::magic_links::AuthenticateRequest;

let resp = client.magic_links.authenticate(AuthenticateRequest {
    token: String::from("DOYoip3rvIMMW5lgItikFK-Ak1CfMsgjuiCyI7uuU94="),

Example B2B usage

Create an API client:

let client = stytch::b2b::client::Client::new(
    project_id: "project-live-c60c0abe-c25a-4472-a9ed-320c6667d317",
    secret: "secret-live-80JASucyk7z_G8Z-7dVwZVGXL5NT_qGAQ2I=",

Create an organization

use stytch::b2b::organizations::CreateRequest;

let resp = client.organizations.create(CreateRequest{
    organization_name: String::from("Acme Co"),
    organization_slug: Some(String::from("acme-co")),
    email_allowed_domains: Some(vec![String::from("acme.co")]),

Log the first user into the organization

use stytch::b2b::magic_links_email::LoginOrSignupRequest;

let resp = client.magic_links.email.login_or_signup(LoginOrSignupRequest{
  organization_id: String::from("organization-id-from-create-response-..."),
  email_address: String::from("admin@acme.co"),

Handling Errors

The error type for all Result values is stytch::Error. If the error is from the Stytch API, this will be the stytch::Error::Response variant, which always includes an error_type field you can use to identify it:

let resp = client.magic_links.authenticate(AuthenticateRequest{
    token: String::from("not-a-token!"),

match resp {
    Err(stytch::Error::Response(err)) => {
        if &err.error_type == "invalid_token" {
            println!("Whoops! Try again?");
        } else {
            println!("Unexpected error type: {}", err.error_type);
    Err(err) => println!("Other error: {:?}", err),
    Ok(resp) => println!("Unexpected success: {:?}", resp),

Learn more about errors in the docs.

Cargo Features

  • reqwest-rustls-tls: Enable reqwest's rustls-tls feature for the rustls implementation.
  • reqwest-native-tls: Enable reqwest's native-tls feature for the native TLS implementation. (This is enabled by default.)
