What is an API-first company?

API-first is the new model of software development in which applications are conceptualized and built as an interconnection of internal and external services through APIs.

An API-first company is an organization that has adopted the API-first development model.

Before API-first, there was code-first.

Code-first is a development model in which applications are built by welding together monolithic pieces of code in cumbersome, and often fragile ways.

Unfortunately, most companies are still code-first companies, and most companies want to become API-first.

Are you an API-first company?

API-first companies answer yes to all the following questions:

  • Do you make APIs available to your customers and partners?
  • Do you know how to organize and discover your APIs?
  • Do you have standardized processes to build APIs?
  • Do your APIs meet regulatory requirements?
  • Do you know the security risk to your API perimeter?

How do you become an API-first company?

Take the following actions to become an API-first company:

  1. Inventory your databases, applications, and services—understand exactly how many APIs you have, and where you lack APIs
  2. Understand your organization's approach to producing APIs—identify where standard processes exist, and where they don't
  3. Define your business domain boundaries and map your organizational structure to those boundaries
  4. Adopt an API platform, and standardize on it
  5. Train your engineering, DevOps, and product management teams on API-first practices

Build your first API-first API!


API-first companies have happier developers.

At API-first companies:

  • Developers don't spend time in meetings
  • Developers don't spend time debugging someone else's code
  • Developers don't get paged in the middle of the night
