Boundry with FastAPI

Create the client during application startup and close it during lifespan shutdown.

Install

This guide uses the official boundry-sdk package. Its generated source is public on GitHub.

Shell
pip install boundry-sdk

Add the server-side helper

Store BOUNDRY_API_KEY in the framework’s secret or server environment. Never include a project key in browser code.

app/email.py
python
import os
from boundry import Boundry

client = Boundry(api_key=os.environ["BOUNDRY_API_KEY"])

def send_welcome_email(to: str):
    return client.emails.send({
        "from": "Acme <hello@acme.com>",
        "to": to,
        "subject": "Welcome to Acme",
        "html": "<p>It works.</p>",
    })

Production checklist

  • Send only from a domain verified in this regional project.
  • Move user-facing sends to the framework’s job system when available.
  • Reuse an idempotency key if you retry after an uncertain response.
