An API is an abbreviation that stands for Application Programming Interface. An API makes it possible to provide other systems and software with an 'entrance' to the system. With this entrance, different systems can communicate and exchange data with each other.
To explain an API simply, we often make the comparison with a plug and a power strip. A power strip can be seen as the system or software. The plug can be seen as the API in this case. If the plug fits into the power strip, they can communicate with each other. However, worldwide there are different types of power strips, which means they do not always fit together. The API documentation tells you which power strips the plug actually fits into.
How does an API connection work?
If two systems need to communicate with each other, the system uses an API to address the other system. The necessary data is then exchanged via the API. An API can be developed to be fully flexible. This means there are practically no limits to how open you want to set the door.
Webservice remote API
If two systems need to 'speak' to each other via the internet, this often happens via a web service. Web services are remote APIs. Usually, this API can be requested via a specific URL that then returns an XML or JSON format. An example of a web service is https://json.buienradar.nl/. Through the link, you will find a JSON description of the weather in the Netherlands. Based on this, you can develop an application that reads the weather via this API and displays it graphically in your own application.
Difference between SOAP and REST APIs
Standards in web services come in all shapes and sizes, but nowadays the most commonly used types are SOAP and REST connections.
SOAP API
SOAP is a connection in which you strictly define how your connection looks. This provides structure and control. The disadvantage of this is that the connection is heavier than a REST connection. You draw up a kind of contract on how the connection should be used. Technically speaking, reading a SOAP connection can be quite a challenge. Fortunately, there are many good helper tools.
REST API
A REST connection is much lighter because you don't use a "contract" for it. The disadvantage of a REST connection is that some complex connections are therefore more complicated to develop than with SOAP. After all, there is less structure.
Nubos is your partner for API connections
Developing and using an API is always a technical matter. Depending on the complexity of the project, an expert is therefore necessary.
At Nubos, we specialize in creating API connections between existing back-office software, such as CRM systems, accounting packages, and our customers' platforms. With years of experience in building connections, most software APIs hold no secrets for us. We tailor all our API connections to ensure the necessary information reaches the right place.
