Bird Python SDK

The official Python SDK for the Bird email platform.

📚 Documentation: https://bird.com/docs/sdks/python

Status: in development. The PyPI distribution name is messagebird-sdk; the import package is bird.

Requires Python 3.10+.

Install

pip install messagebird-sdk      # or: uv add messagebird-sdk

This SDK is generated from Bird's public OpenAPI bundle inside Bird's internal monorepo, which is the single source of truth; this repository tracks tagged releases. Generation runs in the monorepo, so make generate won't work from a clone here — see CONTRIBUTING.md.

Quickstart

from bird import APIError, Bird

with Bird() as client:
    try:
        message = client.email.send(
            from_={"email": "onboarding@messagebird.dev", "name": "Bird"},
            to=["delivered@messagebird.dev"],
            subject="Hello from Bird",
            html="<p>My first Bird email.</p>",
        )
        print(message.id, message.status)
    except APIError as err:
        print("send failed:", err)

api_key and base_url fall back to the BIRD_API_KEY / BIRD_BASE_URL environment variables, so Bird() with no arguments works when they are set. Use the client as a context manager (with Bird(...) as client:) to close the underlying HTTP connection pool.

Email

# Send
message = client.email.send(from_="hi@acme.com", to=["c@x.com"], subject="Hi", text="hello")

# Fetch
message = client.email.get("em_01krd…")

# List — iterating the page auto-paginates across cursors
for message in client.email.list(status="delivered"):
    print(message.id, message.status)

Client-wide email defaults

Defaults fill any unset send field; a per-send value always wins.

client = Bird(
    api_key="bk_eu1_...",
    email_defaults={"from_": "noreply@acme.com", "reply_to": ["support@acme.com"]},
)
client.email.send(to=["c@x.com"], subject="Receipt", text="…")  # uses noreply@acme.com

WhatsApp

Templates are currently the only supported content type, so every send must include one; Bird selects the sender number from the template's category.

# Send
message = client.whatsapp.send(
    to="+31612345678",
    template="bird_otp",
    language="en",
    components=[{"type": "body", "parameters": [{"type": "text", "text": "123456"}]}],
)

# Fetch
message = client.whatsapp.get("wam_01krd…")

# List — iterating the page auto-paginates across cursors
for message in client.whatsapp.list(status=["delivered"]):
    print(message.id, message.status)

Realtime

Every Realtime call is scoped to one Realtime app and authenticated with that app's own key and secret — separate from your Bird API key — configured once on the client. Calling a Realtime method without them raises BirdError before any request is sent.

client = Bird(api_key="bk_eu1_...", realtime_key="rk_...", realtime_secret="rs_...")

# Publish one event to up to 100 channels
client.realtime.publish(
    "rap_01krd…",
    event="order-updated",
    channels=["orders", "orders-42"],
    data={"id": 42, "status": "shipped"},
    exclude_connection_id="81721.1907241",  # don't echo back to the client that acted
)

# Publish up to 10 events at once — each targets a single channel
client.realtime.publish_batch(
    "rap_01krd…",
    events=[
        {"event": "order-created", "channel": "orders", "data": {"id": 1}},
        {"event": "order-updated", "channel": "orders", "data": {"id": 2}},
    ],
)

# Live channel state — a snapshot, not a paginated collection
for channel in client.realtime.channels.list("rap_01krd…", prefix="presence-").data:
    print(channel.name)

channel = client.realtime.channels.get("rap_01krd…", "presence-lobby", include=["member_count"])
members = client.realtime.channels.members("rap_01krd…", "presence-lobby")

# Close every connection authenticated as this member
client.realtime.members.disconnect("rap_01krd…", "member:42")

Webhooks

from bird import Bird, WebhookVerificationError

client = Bird(api_key="bk_eu1_...", webhook_secret="whsec_...")

# In your web handler — pass the RAW request body (bytes) and the request headers
try:
    event = client.webhooks.unwrap(request.body, request.headers)
except WebhookVerificationError:
    return Response(status=400)

if event.root.type == "email.delivered":
    print("delivered:", event.root.data.message_id)

Endpoint management (registering/listing webhook endpoints) is not in this release; it returns once the delivery substrate stabilises.

Errors

Every failure raises a typed exception rooted at BirdError. APIError covers anything that goes wrong issuing a request — including transport failures — so a single except APIError is enough; APIStatusError carries the HTTP status_code.

from bird import APIStatusError, RateLimitError, ValidationError

try:
    client.email.send(
        from_={"email": "onboarding@messagebird.dev", "name": "Bird"},
        to=["delivered@messagebird.dev"],
        subject="Hello from Bird",
        text="My first Bird email.",
    )
except RateLimitError as err:
    print("rate limited; retry after", err.retry_after)
except ValidationError as err:
    print(err.status_code, err.details)
except APIStatusError as err:
    print(err.status_code, err.code, err.request_id)

Transient failures (timeouts, 429, 5xx) retry automatically with jittered backoff that honors Retry-After; a mutation reuses one idempotency key across attempts, so a retried write never double-applies.

Raw response

Reach the status, headers, and request_id alongside the parsed model:

raw = client.email.with_raw_response.send(from_="hi@acme.com", to=["c@x.com"], subject="Hi", text="…")
print(raw.status_code, raw.request_id)
message = raw.parse()

Async

AsyncBird mirrors Bird method-for-method — await each call and async for over a list:

import asyncio
from bird import AsyncBird

async def main() -> None:
    async with AsyncBird(api_key="bk_eu1_...") as client:
        await client.email.send(from_="hi@acme.com", to=["c@x.com"], subject="Hi", text="hello")
        async for message in client.email.list(status="delivered"):
            print(message.id)

asyncio.run(main())

Configuration

client.with_options(...) derives a new client (reusing the connection pool); every method also takes a trailing options for per-call timeout / max_retries / idempotency_key / extra_headers.

Escape hatch

Any endpoint outside the typed surface is reachable through the verb methods, with the same auth, retries, and idempotency:

from bird import EmailMessage

message = client.get("/v1/email/messages/em_01krd...", cast_to=EmailMessage)
client.post("/v1/some/new/endpoint", body={"key": "value"})

Design

The wire models are generated from the OpenAPI spec into bird._generated; this package is the hand-written idiomatic layer on top.
