In this tutorial on the Zaengle blog Jesse Schutt shows you how to use a Laravel application as an "intermediary" between several services and tie them together so a single action could kick off a series of events.

One of our clients recently came to us with the following workflow they'd like the Zaengle team to implement for them: They wanted to compose a blog entry in their CMS. Upon publishing of the entry, they wanted the content of the blog entry to be emailed to a filtered group of their customer database (stored in Marketo). Finally, they wanted to be able to track email metrics from within their customer database.

[...] After brainstorming with the team and client, we decided that since there were at least 3 different systems in play (CMS, Customer Database, & Mail Processor), we needed to write a custom application that would bring all of them together.

He then walks you through the solution they came up with, showing how it makes use of webhooks, API requests and work with their own database. He talks briefly about some of the benefits of the setup and how they arranged the testing of the data flow between the pieces of the system.
