uv add beaco   # or: pip install beaco

import os

from beaco import Beaco

beaco = Beaco(os.environ["BEACO_API_KEY"])
event = beaco.events.publish(
    "user.welcome",
    [{"channels": ["email"], "email": "user@example.com"}],
    inline={"subject": "Welcome", "html": "<h1>Welcome, Alice</h1>"},
)
# Optional sender: inline={..., "from_local": "orders", "from_name": "Winwell Orders",
#                          "reply_to": "support@example.com"}

template = beaco.templates.create("welcome", "email", "Hi {{ name }}")
beaco.templates.upsert_by_name("welcome", "<h1>Hi {{ name }}</h1>")
notification = beaco.notifications.retrieve("ntf_123")
scheduled = beaco.scheduled_events.create(
    "renewal.reminder",
    [{"channels": ["email"], "email": "user@example.com"}],
    "2026-10-02T09:00:00Z",
)
suppression = beaco.suppressions.create("email", "blocked@example.com")

Attachments

Attach files to an email event with attachments. Beaco never stores them: the email provider downloads each url when sending, so the URL must stay reachable until delivery succeeds, including retries. size_bytes is the size you declare; up to 10 files and 30 MB in total.

beaco.events.publish(
    "invoice.issued",
    [{"channels": ["email"], "email": "user@example.com"}],
    inline={"subject": "Your invoice", "html": "<p>Invoice attached.</p>"},
    attachments=[
        {"filename": "invoice.pdf", "url": "https://files.example.com/a.pdf", "size_bytes": 48213}
    ],
)

Invalid attachments raise ValueError before any request is made. URLs must be publicly reachable: private and internal addresses are refused.

Requires Python 3.9 or newer. This package is server-only: never expose a project API key in browser code.
