ckanext-webhooks
Webhooks for your CKAN. For example, as an app developer you want to be notified
when a dataset your app depends on is updated. This extension allows users and
services to register to be notified for common CKAN events, such as:
- Dataset Events - new, update, delete
- Resource Events - new, update, delete
Subscribers provide a callback url when registering for an event, and CKAN will
call that url when the desired event happens.
Installation
Add webhooks to your CKAN plugins:
.. code::
ckan.plugins = ... webhooks
The extension pushes webhook notifications onto the CKAN celery queue, so that
the web app won’t block executions while the webhooks are firing. For this
reason you need to make sure the celery daemon is running:
.. code::
paster --plugin=ckan celeryd -c development.ini
Or if you are using datacats:
.. code:
datacats paster celeryd
Usage
At the moment there is no web interface to create Webhooks. Please make one if
you’re up for it! For now, hooks must be registered through the action API.
For example:
.. code:: python
import ckanapi
ckan = ckanapi.RemoteCKAN('http://some.ckan.org')
#create webhook
hook = ckan.action.webhook_create(topic="dataset/create", address="http://example.com/callback")
#show webhook
ckan.action.webhook_show(id=hook)
#delete webhook
ckan.action.webhook_delete(id=hook)
Supported Topics
- dataset/create
- dataset/update
- dataset/delete
- resource/create
- resource/update
- resource/delete
Authentication
There is a minimal authentication as you may restrict creation of webhooks to users
who are editors or administrators of organisations. You may add a config option
to your CKAN file as below where the value is one of editor, admin, sysadmin or
none, specifying the minimum roles required to be able to interact with webhooks.
# Only let sysadmins create hooks
