![]() ![]() Once the server validates that the correct username and password have been provided, the user is granted access to the application.Īnother context to think about API calls in is when you go to book a flight. Examples of API callsĬircling back to the example above, the submission of a user’s log-in credentials via an app prompts an API call for the server to provide access. The request is assessed and forwarded to an external program, which then passes back data to give the user a response. Once an API is set up and ready for use, a developer adds an endpoint to the URL that allows requests to be made to the API for more information. Like telephones, API calls enable APIs to talk to one another and exchange information. Once you click “Enter,” the information shared is sent to the API. ![]() If you’ve ever downloaded an application - whether it’s to learn a new language or manage your bank accounts - you’ve likely been asked or prompted to fill in personal information like your email address and password after the download is complete. One of the most critical elements behind this exchange of data and functionality is API calls. Alongside these results, the survey indicates that 68% of developers expect to increase API use in 2022.Īmid the growing conversation around APIs and their use, questions have naturally popped up about the parameters and protocols working behind the scenes of APIs. In a 2022 survey of 2,200 developers, 74% said they are using APIs for internal applications, 49% are working on third-party APIs, and 44% are working on partner-facing APIs. With the benefits APIs bring to the table and digital transformation across all industries, it’s natural that the adoption of APIs has risen over the years. To put this into perspective, research showed that firms using APIs over a four-year period experienced 12.7% more market capital growth compared to those who did not use APIs. Rather than starting from scratch, developers can leverage resources already at their disposal to drive cost-effective and efficient product innovation. Designed to simplify software development, APIs enable developers to use other technologies and data as building blocks in their applications. The wave of API adoptionĪpplication program interfaces, or APIs, are defined as a set of procedures and tools for building software applications. To further explain what an API call is, let’s start with the basics of APIs. ![]() ![]() The functionality of application programming interfaces (APIs) is built upon several layers - one of which includes requests made to APIs to retrieve a service or data, or what’s otherwise known as an API call. ![]()
