How Do You Build an API?

Application programming interface (API) is the interaction or communication process of programs, internally or externally. In simpler terms, think of API as the waiter in a restaurant. You’re the customer (a program or system) ordering food, but your order (data) needs to get to the kitchen (the other program or system). This is when the waiter (API) comes into play. The waiter, or API, is the messenger that will take your order (data) to the kitchen, and then bring your order back to the table. This example shows exactly how the communication process works with APIs. 

With API, it is not only easy to develop a computer program with the help of a programmer, as they can make changes to certain areas of your website, but it also eliminates the risk of rewriting an entire computer program.

How does software communicate with internal and external software through API?

  1. Data Sources: Programmers store their data in the form of databases.  to a text file, text can either update the data sources manually or through API based on their level of access (read or write-only). 
  2. Format of Request Sent: API Request is sent with – GET, POST, PUT, AND DELETE methodologies.  An API rule completes the processing or operation of API requests. You just have to specify whether you’re going to use dynamic or explicit actions, which will make it easier for external programs to understand and process the request sent. All the request parameters are mentioned in API Request Documentation, and these will be used in the response document. 
  3. Response: After a request is made, a response in return should follow. API needs to send a response back to the software from where the request was received. The responses may include a status code like “500,” which is a standard error code.  The message “Internal Server Error” is a common response. This particular code indicates that the server encountered an unexpected condition that prevented it from being able to complete or fulfill a request. The error is then usually returned to by the server if there isn’t another suitable or appropriate error code.  

What to Consider While Building an API

Access

While building an API it must be clear to whom access is given. Programmers can always restrict the usage of API or put limitations by API Keys, JSON Web Token, or any other such options.  

Documenting

Every API needs some form of documentation, so the programmers can know how API is used. The documentation should include the request, format, and the type of data inputs and responses.  

Role

Authentication is required in API. Access to certain internal parts of API is allowed; however, external access is not allowed.  Developers are unable to create route-based permission; that means unauthorized people aren’t allowed to access it.  

Analytics

Analytics helps you to trace the errors faced by users. Also, developers can track how often API is used. With this, you can check every request and response, as well as failed ones. This allows programmers to  limit or restrict the usage of API and trace it as well. This, ultimately, improves productivity and reduces unwanted, redundant API calls done via the program. 

Limiting usage

It is great to provide access to people externally, but at the same time, it is necessary to control the usage. Developers can limit users to save the app from crashing from multiple requests. Thus, limiting usage is also an inevitable part of API. 

Speed control

Speed of the web is mostly dependent on the type of users/target audience you have as well the type of webpage. With the help of API, developers can manage the responsive speed according to the requirement. Flashing news websites will require more speed than others where as a typical lifestyle blog website won’t necessarily require as much speed. However, studies show that the average time it should take a website to load is three seconds or less; if you have an e-commerce site, your site needs to load in two seconds or less. The faster a website loads, the longer users will stay on your website. 

Advantages of API

There are many advantages of opting for API, and this can really help your webpage or app perform better. If there are good reasons to build API, why not implement API programming? So, let’s go through the advantages.  

  • A good API solution helps to increase productivity of the program.  
  • Every developer program provides customer satisfaction.  
  • Marketing scopes are improved. 
  • API is a cost-effective solution because it is the safest and fastest way to communicate between software. 
  • New and innovative ideas can be developed in API and scope of innovation can be created. 
  • Any issues or errors can be resolved by collecting data from analytics in API.API helps in creating new income opportunities.
