What is an API?<\/h2>\r\n\r\n\r\n\r\n
API = Application Programming Interface<\/h3>\r\n\r\n\r\n\r\n
It is an interface that allows applications to communicate between themselves. There are different types of APIs:<\/p>\r\n\r\n\r\n\r\n
\r\n
Operating system APIs allows software to interact with devices or IoT, to recognise gestures (touch screen, etc).<\/li>\r\n\r\n\r\n\r\n
Programming language APIs allow developers to use predefined functions, so they don’t have to reinvent the wheel.<\/li>\r\n\r\n\r\n\r\n
Infrastructures APIs allow developers to change the available resources to run an application via the cloud (virtual machines, servers, network architecture, etc.) : Amazon Web Services, Google Cloud Platform, Microsoft Azure, etc.<\/li>\r\n\r\n\r\n\r\n
Web APIs allow querying services provided by web platforms. From Google Maps backgrounds to Facebook’s Social Graph and passing through tweet monitoring, this is the fastest growing category of API. For example, Airbnb uses the Google Maps API to turn the addresses of rental properties into geotags.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
The REST API<\/h3>\r\n\r\n\r\n\r\n
Today, introducing photos with two clicks, tweeting, or saving five terabytes in the cloud are simple operations that no one is surprised by anymore. This ease is made possible by REST APIs. But what exactly are they? How and why were they created?<\/p>\r\n\r\n\r\n\r\n
Before the year 2000, there were no standards on how to conceive an API or how to use it. Its integration required the use of protocols such as SOAP, which was complicated to implement, unwieldy and difficult to debug. But this will change in 2000, when the real potential of Web APIs was recognized: a group of experts, led by Roy Fielding, invented REST and changed the API landscape forever.<\/p>\r\n\r\n\r\n\r\n
The stated objective is to simply create a standard, allowing the communication and the exchange of data between two servers, anywhere in the world. They therefore designed a set of principles of property and restrictions called REST, a resource-oriented architecture:<\/p>\r\n\r\n\r\n\r\n
The caching of the resource representation<\/li>\r\n\r\n\r\n\r\n
The use of the HTTP protocol and its methods.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
The rules are many and universal. Through the correct application of these rules, the API is forced to simplify, and significantly facilitates the integration work.<\/p>\r\n\r\n\r\n\r\n
API in the energy sector<\/h3>\r\n\r\n\r\n\r\n
The energy sector needs to adapt to the new requirements from customers and stakeholders.<\/p>\r\n\r\n\r\n\r\n
\r\n
“94% of energy suppliers report that reacting quickly to operations is a challenge.”<\/li>\r\n\r\n\r\n\r\n
“36% of consumers are ready to pay more for sustainable energy.”<\/li>\r\n\r\n\r\n\r\n
“Energy consumers opt for digital interaction in 8 out of 10 interactions.”<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
“Companies should opt for an agile IT development to answer these challenges effectively. The API can be used for this purpose and increase the pace of digital transformation in the energy sector.”

Technological integration<\/h3>\r\n\r\n\r\n\r\n
The API allows the transmission of collected data. This data can be integrated into a company’s application or can be analyzed to generate an overview.<\/p>\r\n\r\n\r\n\r\n
The API can use the data generated by IoT, which is increasingly present in this sector. The value of IoT in the energy sector is expected to grow over 35 billion dollars by 2025.<\/p>\r\n\r\n\r\n\r\n<\/figure>\r\n\r\n\r\n\r\n

The following are some examples of APIs in the energy sector:<\/p>\r\n\r\n\r\n\r\n
\r\n
SMAPPEE<\/strong>: This API allows the collection and monitoring of solar, gas and water energies used with the API. In addition, events and cost analyses of devices can be collected using their API.<\/li>\r\n\r\n\r\n\r\n
GENABILITY<\/strong>: This API gives information on electricity prices, such as taxes and seasonal rates.<\/li>\r\n\r\n\r\n\r\n
SCHNEIDER<\/strong>: The Schneider Facility Experts Data API supervises and tracks equipment and building data. The API can supervise and set alerts for events such as overheating of cables, loss of voltage, and equipment failure.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
