Conclusion
Again, workflows are useful tools to setup process that occurs before or after the publication of a content. They can be as simple as the content approval process and can be much more complex and combined to the object states they can be very powerful.
We have seen in this tutorial how to setup a workflow and link it to a trigger and we applied it to a content approval process. We have then been through an example of a workflow that automatically post a status update to a Twitter account. Additionally, because of some technical restriction from Twitter, we have also developed a little CLI script which acts as a helper with Twitter’s OAuth.
With these examples, you should now be able to develop your own workflow events for your website needs.
