5 Rules of Web API Design
1. Need a good documentation
Many people hate writing documentation and try using undocumented API. If you want to use your API, it is essential to have good documentation. The first thing users will see how you have presented your API. If you have presented your API well, people are more likely going to use.
There are some software tools that simplify the task of documentation. You can write the endpoints and functions of your API to generate the corresponding documentation. You must include examples and tutorials to make your documentation look presentable. Once you are done with the documentation, make sure you validate it to find whether it makes sense to people.
2. Design API endpoints to be documents and provide extra data.
Many developers used to design APIs that can reflect internal data base model. This is not a good idea. So you have to design a data base model which is normalized and atomic. They should be flexible and efficient. Ensure the database transaction tools control flow and include transaction safety.
Every single request has to be executed in an isolated fashion. One main complaint about REST is that it requires tons of round trips to the server to retrieve the data. You may design an API that can make an extra field optional by default. You must have user request when needed and reduce database hits and bandwidth.
If you have ever used Facebook’s API, you will know how often they rewrite Their APIs. They are successful because they have lots of users not because their API is great. You should never keep your old version running and supporting for a longer period. You need a much less volatile API.

This help people to rely on version 1 and can upgrade to subs equate version. A good URL scheme should include major versions in URL. Addition to this, API needs to be consistent. You must handle common parameters within your API and use shared architecture to reuse data handling throughout your API.
4. They should be flexible
Your API should have some degree of flexibility with regards to output and input constraints. You will find many APIs that support output formats like XML, JSON, and YAML but will support the specifying format in URL itself. As the case of flexibility, you may allow them to be specified in URL itself.
You may read and recognize HTTP header also. Just like there is a variety of output format, you must allow a variety of input format also. You should support standard POST variables and modern applications that support JSON as well.
5. They should be easy to adopt
This is an important rule you must follow. Make sure people can get up and run with the basic implementation of your API. 15 minutes of tutorial must be included for easy following of your API. Make sure your API is simple, and people can use them for the first time and every time.
You should never do any fancy authentication and crazy customer URL scheme. Use the tools that have been implemented and widely accepted, so that developers can learn your API. It is very important to provide language specific libraries that can interface with your service. There are some nice tools available that can generate a library automatically for you. It is very important to provide excellent support to an unsophisticated user. Email support, forums, and bug trackers are a fantastic start.
