What are the Key Activities in an API-First Project?

API lifecycle


APIs are the backbone connecting today’s software applications. Companies make money by selling data and services using APIs or publishing APIs for use by mobile and web applications. Today, the API is the product.

An API is a specific software application being developed, tested, and then operated.


It starts with API design. This approach is called API-First, because the API contract is a first-class artifact of software development, thus emphasizing its strategic and architectural importance.

At the core of API design are specifications used by developers and customers to establish communication between software applications. Poor quality APIs risk breaking existing integrations.

Once you have the API contract and the first implementation then you have to test the API. Without API testing you, your partners, and your customers are at risk of losing time, money and credibility. Your company’s reputation and your customers’ experience can be destroyed by an API malfunction.

API Documentation is an entry point for your customers to evaluate, learn, and to start using your API. Unfriendly, incomplete, or even missing API documentation can significantly damage your business.

API testing and operational automation significantly saves you costs and resources. Imagine you can run thousands task over your API in a second.

At the end you have your API up and running, but that’s only the beginning. Now, you have to secure, operate and monitor the API. That’s generally called API management.

At Talend, we provide an API-First Platform that helps to quickly develop, deliver, and operate APIs . You can learn more about each of these specific use cases below.
