Some examples of APIs used regularly include the following:
Using Google Maps on a website's "Contact" page to show a company's office location is one of the most common uses of APIs. Also, several mobile applications use the Google Maps API for various reasons. For example, all food delivery applications such as SkipTheDishes or Uber Eats use the Google Maps API to help their drivers find delivery locations and also use the same API to show the customer the driver's route and how far they are from their house. The whole Uber platform is in essence built from API calls rather than custom code. The Google Maps API is a key component of the Uber application used to help drivers and riders find and connect through the Uber app.
Embedding YouTube videos or social media posts on a website is done with the use of web APIs. Providers like Facebook or Twitter provide a free and open API to developers to add to a website to access Facebook's or Twitter's data and services.
Companies like Amazon, Shopify, Spotify, and other private corporations share their APIs with partners so that their partners can access their data and generate revenue for both parties. An example of this is Google Flights. Google accesses the APIs of several different airlines and then makes this information available to users in the Google Flights portal and allowing them to search and find the best itinerary and price across several different airlines, for their next flight.
There are many benefits of using APIs for both developers and businesses.
The primary benefit of an API is that it allows a company (their development team) to access information or software capabilities from another source, and provide greater value to its customers without an additional investment of time, money, and resources. As mentioned earlier in this post, a good example would be the Google Maps API which is a key component for businesses like Uber, or food delivery applications such as SkipTheDishes or DoorDash. By using Google's "Google Map API", these businesses save on development costs (as they don't need to develop a brand-new state-of-the-art mapping system for their apps). They also provide their customers with the benefit of using one of the best mapping applications available, an application their customers are most likely already very familiar with.
As discussed earlier, in addition to the benefits that APIs offer businesses through the software development process (for their developers), they also present an opportunity for businesses to leverage their data and internal tools and solutions into new revenue streams and business opportunities. Companies like Google or Amazon generate revenue by selling access to some or all of their APIs.
Many companies also monetize their APIs in different ways, such as encouraging customer loyalty or using the APIs as marketing tools to become integral to their customers' business, driving awareness for their brand, or exploring new business opportunities. Good examples of this are Google Maps (an API which is mostly offered at no charge from Google), or Slack's basic API which allows companies to integrate Slack's messaging tool into other applications they use. By doing this, Slack becomes integral to this company's business and eventually can upsell them a different (for a fee) API option.
There are tens of thousands of APIs available for use today, each providing access to prebuilt functionality businesses and development teams can use to provide better customer experiences faster than trying to build that functionality in-house from scratch. Alternatively, businesses can also develop APIs and offer them to their clients for free (for marketing/sales purposes), or for a fee. Either way, APIs are an important part of modern software development as they provide important opportunities and innovative ways for companies and development teams to improve their offering and grow their business. Based on this, it's only fair to assume that the potential and opportunities of APIs will only continue to grow in the future.
