I have been working in SAAS solutions for many years now and it is interesting to see how technologies are evolving & applications / web APIs are connecting to each other to get seamless & quick end to end integration between systems & organizations.

Webhook – A lightweight HTTP pattern providing a simple pub/sub model for wiring together Web APIs and SaaS services. It’s been an year that this new concept been introduced in my product (thanks to our great Architect) and I see lot of benefits with it.

  • Now our product can send notifications to the subscribed customers for the predefined events that happens in the product.
  • It’s also used to show the changes between two major statuses in our workflow system
  • We also thought about using it to build reporting data warehouse instead of building warehouse using the typical approach of ETL/batch jobs.

So there may be many such usecases that one can think about to see whether this can fit. The first use case i.e. sending notification with data on an event is a very natural usecase that many products can use this. More examples …

  • File has changed in Dropbox
  • Code change has been committed in GitHub
  • Payment has been initiated in PayPal
  • Card has been created in Trello
  • Post P1 bug to a slack group
