rerout-django 0.1.0

Official Django integration for the Rerout branded-link API.

rerout-django

Official Django integration for the Rerout API.

Wraps the base rerout SDK with Django-native ergonomics: a settings-driven, cached API client and a signed-webhook receiver view that fans events out as Django signals.

Install

pip install rerout-django
# or
uv add rerout-django
# or
poetry add rerout-django

Requires Python 3.10+ and Django 4.2 or 5.x. Installs the rerout base SDK as a dependency.

Setup

Add the app to INSTALLED_APPS and configure it via a single REROUT settings dict:

# settings.py
INSTALLED_APPS = [
    # ...
    "rerout_django",
]

REROUT = {
    "API_KEY": env("REROUT_API_KEY"),            # required for the client
    "WEBHOOK_SECRET": env("REROUT_WEBHOOK_SECRET"),  # required for webhooks
    # Optional:
    # "BASE_URL": "https://api.staging.rerout.co",
    # "TIMEOUT": 30.0,
    # "SIGNATURE_TOLERANCE_SECONDS": 300,
}

Usage

The API client

get_rerout_client() returns a process-wide, lazily constructed, cached rerout.Rerout instance built from your REROUT settings. It wraps a thread-safe httpx.Client, so sharing the one instance across requests is both safe and recommended.

from rerout import CreateLinkInput
from rerout_django import get_rerout_client

def create_promo(request):
    client = get_rerout_client()
    link = client.links.create(
        CreateLinkInput(target_url="https://example.com/q4-sale", code="q4")
    )
    return JsonResponse({"short_url": link.short_url})

Every method on the client raises rerout.ReroutError on failure — see the base SDK README for the full surface (links, project, qr) and error handling.

reset_rerout_client() drops and closes the cached client; the next get_rerout_client() call rebuilds it. This is mostly useful in tests that swap REROUT settings between cases.

Receiving webhooks

WebhookView is a CSRF-exempt view that verifies the X-Rerout-Signature header, parses the JSON body, and dispatches Django signals. Mount the bundled URLConf:

# urls.py
from django.urls import include, path

urlpatterns = [
    path("rerout/", include("rerout_django.urls")),
]

That serves the endpoint at /rerout/webhook/ (URL name rerout_webhook). Prefer a different path? Wire the view directly instead:

from rerout_django import WebhookView

urlpatterns = [
    path("hooks/rerout/", WebhookView.as_view()),
]

The view responds:

Status	Meaning
200	Signature valid, body parsed, signals dispatched.
401	Signature missing, malformed, or invalid.
400	Signature valid but the body is not a JSON object.

Signature verification uses the base SDK's verify_rerout_signature with a configurable timestamp tolerance (REROUT["SIGNATURE_TOLERANCE_SECONDS"], default 300; set 0 to disable the staleness check).

Reacting to events with signals

Subscribe to the signals in rerout_django.signals — do not subclass WebhookView. Every verified delivery fires rerout_webhook_received; events with a recognised type also fire a dedicated signal.

from django.dispatch import receiver
from rerout_django import rerout_link_clicked, rerout_webhook_received

@receiver(rerout_link_clicked)
def on_click(sender, event, payload, request, **kwargs):
    print(payload["code"], "was clicked")

@receiver(rerout_webhook_received)
def log_everything(sender, event, payload, request, **kwargs):
    print("received", event)

Every signal is sent with these keyword arguments:

Argument	Description
sender	The WebhookView class.
event	The event type string (e.g. "link.clicked").
payload	The full parsed JSON body, as a dict.
request	The HttpRequest that delivered the webhook.

Available signals:

Signal	Event type
rerout_webhook_received	every event
rerout_link_created	link.created
rerout_link_updated	link.updated
rerout_link_deleted	link.deleted
rerout_link_clicked	link.clicked
rerout_qr_scanned	qr.scanned

Error handling

Configuration problems raise django.core.exceptions.ImproperlyConfigured:

• get_rerout_client() — when REROUT["API_KEY"] is missing or blank.
• WebhookView — when REROUT["WEBHOOK_SECRET"] is missing or blank.

API call failures raise rerout.ReroutError (with a stable code, an HTTP status, and convenience flags is_rate_limited / is_server_error) — see the base SDK for details.
