In our last Python Flask blog post, we walked through building a simple application to take in a Threat Stack webhook and archive the alert to AWS S3. In this post, we’ll dive into Python exception handling and how to do it in a secure manner.

The code in the last post was written to be as simple and readable as possible. However, what happens if something goes wrong in our application? There’s no error or exception handling. If something goes wrong — for example, we hit a bug or receive bad data — there’s nothing we can do about it in the application. Instead of returning a parseable JSON response, the app will just spit a backtrace embedded in an HTML document back. The entity sending the request to our service is then left trying to figure out what may have gone wrong.

Many of our customers are building useful services using our webhook feature — but unfortunately, others are not. Often we hear that no one on their team is proficient enough to write a service that can ingest a webhook payload and do something with the data. That leaves them either hoping to get cycles from their development team (unlikely) or continuing to do without.

But what if you could write your own web services? How many routine tasks that involve taking data from system A and inputting it into system B could you automate? 

Learning to code well enough can be a major skill in your tool chest and a major asset for optimizing security processes in your organization.

So in this post, I’m going to walk you through a tutorial that will get you started on the road to writing your own web services using Python Flask.
