A presentation at API World in in San Jose, CA, USA by Shy Ruparel
My App Broke And it’s all the API’s fault
Shy Ruparel Developer Evangelist | Contentful @ShyRuparel He/Him
Don’t let a CMS get in the way of shipping software. Contentful provides a content infrastructure that enables teams to power content in any digital product.
Let’s talk about Software Engineering
Regardless of what you make Something is gonna break
Stuff breaks
Use APIs Writes APIs
How do we Minimize risk?
If you can change an API In a way that breaks your codebase
And you can’t make that change programmatically
Let’s take a look at Databases
DON’T FUCK IT UP Critical to business Store user data In Sync with Codebase Outages translate to $$ lost
Production should be Non-Trivial to change
Fun Fact: SQL is 44 years old
Database Migrations No more developers manually alternating a DB Schema alterations as code Version Control for Migrations Repeatable and Testable
Cool. Can we talk about APIs again?
Can we learn anything from Continuous Integration?
Simple CI Pipeline Build Test Deploy
WHAT CI DOES • Forces testing and checks on changes • Automates deployment • Cancelable • Repeatable
Saves Time Creates Trust
Process is key
Ok. Now we can talk about External APIs
Treat APIs like Databases
MAKE PRODUCTION NON-TRIVIAL TO EDIT
WRITE/ENABLE PROGRAMMATIC API MIGRATIONS
API KEYS FOR EVERY BRANCH
Automate your changes via Continuous Integration
TEST YOUR APIS
MAKE CHANGE PART OF DEPLOYMENT
Less Simple CI Pipeline Build - Use Branch API Key - Implement API Configuration Changes Test - Run tests that use that API Deploy - Update Production API Key
Let’s look at a practical Workflow

Utilizing a continuous integration pipeline reduces the risk of failure as code is updated for your application. However, evolutions to a codebase no longer represent all of the changes that a developer could make to an application. Modern development heavily depends on utilizing external APIs to speed up the time it takes to ship code; this creates additional risk of failure as an untested change to a 3rd party system can create unexpected downtime for your application. In this talk Shy Ruparel, developer evangelist at Contentful examines strategies to bring API management into your continuous integration pipeline and outlines how that enables your codebase to integrate, change, and play well with systems outside of your control.
