FastAPI Integration

Reloop can be easily integrated into any FastAPI application.

Installation

Install the official Python SDK:

pip install reloop-python

Setup Environment Variables

Add your API key to your environment:

export RELOOP_API_KEY="re_your_api_key_here"

Sending an Email

Here is a simple FastAPI route that sends an email:

import os
from fastapi import FastAPI, HTTPException
from reloop import Reloop

app = FastAPI()
reloop = Reloop(api_key=os.environ.get("RELOOP_API_KEY"))

@app.post("/send-email")
async def send_email():
    try:
        response = reloop.emails.send(
            sender="onboarding@reloop.dev",
            to="delivered@resend.dev",
            subject="Hello from FastAPI",
            html="<p>Congrats on sending your first email via Reloop from FastAPI!</p>"
        )
        return response
    except Exception as e:
        raise HTTPException(status_code=500, detail=str(e))
