APIs – Solving the Developer Gap
As companies realize the importance of accelerating their digital transformation and software-centric initiatives, they increasingly turn to investment in software development. However, a shortage in software developers combined with tough hiring conditions amidst the “Great Resignation” makes scaling engineering organizations difficult. As a result, many companies are looking for tools – such as APIs – to bridge their developer shortage.

The developer gap has fueled the rapid expansion of the API economy – which is currently growing at over 63% CAGR. APIs – which provide encapsulated pieces of functionality that developers can embed in their apps function like “lego pieces” – save developers critical time when adding common functions to their applications such as charging credit cards, sending messages, or getting geo-location information.

RapidAPI’s The State of Enterprise APIs Survey found that nearly all respondents (98%) believe that APIs are an essential part of their organization’s digital transformation, and 97% agree that successfully executing an API strategy is essential to secure organizations’ future revenue and growth. Its State of APIs Developer Survey found that a majority (68.5%) of developers indicated that they will rely on APIs more in 2022 for all their coding projects.
