Increasingly more, improvement groups are adopting an API-first approach to software program improvement, wherein APIs are the constructing blocks of software program and every thing else is constructed round them. That is in distinction to code-first, the place the complete software — together with the API, UI, and different elements — is deliberate out collectively on the similar time.
In response to Postman’s 2024 State of the API report, 74% of respondents adopted the API-first method in 2024, in comparison with 66% final 12 months. “APIs are now not an afterthought however the basis of improvement, with between 26 and 50 APIs powering the common software,” Postman wrote within the report.
The advantages of this technique embrace quicker API manufacturing and quicker restoration from failures. This 12 months, 63% of respondents had been in a position to produce an API inside one week (up from 47% final 12 months). Moreover, organizations following this method can sometimes get well from API failures in beneath an hour.
“By prioritizing API design, governance, and safety, groups can unlock new alternatives, ship APIs quicker, and guarantee their APIs are protected and optimized for the longer term,” Postman stated.
Whereas there are various advantages to API-first, it doesn’t fully eradicate the challenges API builders face, reminiscent of poor documentation and lack of correct collaboration.
Thirty-nine p.c of respondents declare inconsistent documentation is the largest roadblock to API improvement. Forty-four p.c learn by supply code to know their APIs, however over half collaborate with individuals who don’t perceive the code, like product managers, high quality assurance, and designers. Forty-three p.c additionally battle with getting info from different builders who could also be working asynchronously in several time zones.
The report additionally discovered that one third of respondents are utilizing a number of gateways for his or her APIs, signaling that “the normal single-gateway mannequin is changing into out of date.”
One other optimistic discovering is that 62% of respondents are producing revenue from their APIs, and 33% report that APIs make up over 50% of their whole income.
“APIs are now not simply technical enablers—they’re revenue-generating merchandise … This alerts the rise of the API-as-a-product mannequin, the place APIs are designed, developed, and marketed as strategic property,” the report said.
And eventually AI is leading to elevated API utilization as nicely, with AI-related visitors on Postman’s platform growing by 73% within the final 12 months. Corporations at the moment are having to create APIs not only for people, however for interfacing with AI programs as nicely.
“The age of AI is powered by APIs. The fast adoption of chatbots like ChatGPT has confirmed that AI bots are going to advance the state of human-computer interplay. Till now, we have now primarily been designing APIs for people, however designing APIs for machines will grow to be an more and more necessary space… and AI alone gained’t enhance productiveness—you want high quality APIs to remain forward in fashionable software program,” the report concluded.
For its survey, Postman surveyed greater than 5,600 builders and API professionals, and made observations based mostly on the exercise of the 35 million+ customers on its platform.
