Increasingly, improvement groups are adopting an API-first strategy to software program improvement, wherein APIs are the constructing blocks of software program and every little thing else is constructed round them. That is in distinction to code-first, the place the total utility — together with the API, UI, and different parts — is deliberate out collectively on the similar time.
In keeping with Postman’s 2024 State of the API report, 74% of respondents adopted the API-first strategy in 2024, in comparison with 66% final 12 months. “APIs are not an afterthought however the basis of improvement, with between 26 and 50 APIs powering the typical utility,” 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 have been in a position to produce an API inside one week (up from 47% final 12 months). Moreover, organizations following this strategy can usually get better from API failures in underneath 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 lots of advantages to API-first, it doesn’t completely eradicate the challenges API builders face, reminiscent of poor documentation and lack of correct collaboration.
Thirty-nine % of respondents declare inconsistent documentation is the largest roadblock to API improvement. Forty-four % learn by means of 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 % additionally wrestle with getting info from different builders who could also be working asynchronously in numerous 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a number of gateways for his or her APIs, signaling that “the standard single-gateway mannequin is turning into out of date.”
One other constructive discovering is that 62% of respondents are producing revenue from their APIs, and 33% report that APIs make up over 50% of their complete income.
“APIs are not simply technical enablers—they’re revenue-generating merchandise … This indicators the rise of the API-as-a-product mannequin, the place APIs are designed, developed, and marketed as strategic belongings,” the report acknowledged.
And at last AI is leading to elevated API utilization as properly, with AI-related visitors on Postman’s platform rising by 73% within the final 12 months. Firms at the moment are having to create APIs not only for people, however for interfacing with AI techniques as properly.
“The age of AI is powered by APIs. The speedy adoption of chatbots like ChatGPT has confirmed that AI bots are going to advance the state of human-computer interplay. Till now, we now have primarily been designing APIs for people, however designing APIs for machines will change into an more and more essential space… and AI alone gained’t increase productiveness—you want high quality APIs to remain forward in trendy software program,” the report concluded.
For its survey, Postman surveyed greater than 5,600 builders and API professionals, and made observations primarily based on the exercise of the 35 million+ customers on its platform.
