Axum Integration

Integrate Reloop into your Rust application using the Axum web framework.

Installation

Add the official Rust SDK and standard tokio dependencies to your Cargo.toml:

[dependencies]
axum = "0.7"
tokio = { version = "1", features = ["full"] }
reloop-rust = "0.1"

Sending an Email

use axum::{routing::post, Json, Router};
use reloop_rust::{ReloopClient, SendEmailParams};
use std::env;

#[tokio::main]
async fn main() {
    let app = Router::new().route("/send-email", post(send_email));
    let listener = tokio::net::TcpListener::bind("127.0.0.1:3000").await.unwrap();
    axum::serve(listener, app).await.unwrap();
}

async fn send_email() -> Result<Json<serde_json::Value>, (axum::http::StatusCode, String)> {
    let api_key = env::var("RELOOP_API_KEY").map_err(|_| {
        (axum::http::StatusCode::INTERNAL_SERVER_ERROR, "Missing API Key".to_string())
    })?;
    
    let client = ReloopClient::new(api_key);
    
    let params = SendEmailParams {
        from: "onboarding@reloop.dev".to_string(),
        to: vec!["delivered@resend.dev".to_string()],
        subject: "Hello from Axum".to_string(),
        html: "<p>Congrats on sending your first email via Reloop from Rust Axum!</p>".to_string(),
    };

    match client.emails.send(params).await {
        Ok(res) => Ok(Json(res)),
        Err(e) => Err((axum::http::StatusCode::INTERNAL_SERVER_ERROR, e.to_string())),
    }
}
