Django + Webhooks Made Easy

The full documentation is at https://dj-webhooks.readthedocs.org.

Requirements

  • Python 2.7.x or 3.3.2 or higher
  • django>=1.5.5
  • django-jsonfield>=0.9.12
  • django-model-utils>=2.0.2
  • django-rq>=0.6.1
  • webhooks>=0.3.1

Quickstart

Install dj-webhooks:

pip install dj-webhooks

Configure some webhook events:

# settings.py
WEBHOOK_EVENTS = (
    "purchase.paid",
    "purchase.refunded",
    "purchase.fulfilled"
)

Add some webhook targets:

from django.contrib.auth import get_user_model
User = get_user_model()
user = User.objects.get(username="pydanny")

from webhooks.models import Webhook
WebhookTarget.objects.create(
    owner=user,
    event="purchase.paid",
    target_url="https://mystorefront.com/webhooks/",
    identifier="User or system defined string",
    header_content_type=Webhook.CONTENT_TYPE_JSON,
)

Then use it in a project:

from django.contrib.auth import get_user_model
User = get_user_model()
user = User.objects.get(username="pydanny")

from djwebhooks.decorators import hook

from myproject.models import Purchase

# Event argument helps identify the webhook target
@hook(event="purchase.paid")
def send_purchase_confirmation(purchase, owner, identifier):
    return {
        "order_num": purchase.order_num,
        "date": purchase.confirm_date,
        "line_items": [x.sku for x in purchase.lineitem_set.filter(inventory__gt=0)]
    }

for purchase in Purchase.objects.filter(status="paid"):
    send_purchase_confirmation(
        purchase=purchase,
        owner=user,
        identifier="User or system defined string"
    )

Storing Redis delivery logs

Note: The only difference between this and the previous example is the use of the redislog_hook.

from django.contrib.auth import get_user_model
User = get_user_model()
user = User.objects.get(username="pydanny")

from djwebhooks.decorators import redislog_hook

from myproject.models import Purchase

# Event argument helps identify the webhook target
@redislog_hook(event="purchase.paid")
def send_purchase_confirmation(purchase, owner, identifier):
    return {
        "order_num": purchase.order_num,
        "date": purchase.confirm_date,
        "line_items": [x.sku for x in purchase.lineitem_set.filter(inventory__gt=0)]
    }

for purchase in Purchase.objects.filter(status="paid"):
    send_purchase_confirmation(
        purchase=purchase,
        owner=user,
        identifier="User or system defined string"
    )

In a queue using django-rq

Warning: In practice I’ve found it’s much more realistic to use the ORM or Redislib webhooks and define seperate asynchronous jobs then to rely on the djwebhooks.redisq_hook decorator. Therefore, this functionality is deprecated.

Features

  • Synchronous webhooks
  • Delivery tracking via Django ORM.
  • Options for asynchronous webhooks.

Planned Features

  • Delivery tracking via Redis and other write-fast datastores.
