Five Golden Rules of Web API Development


Every software developer knows that web API deployment is less prone to an unresolved web. But if it is constructed properly, it shows the best results. To assist users in making full use of web API, we have come up with five golden Web API development rules.

Five golden rules of Web API Development

Here are the five rules to built optimal web APIs.

  1. Documentation:

The remarkably most accessible part is documenting the API methods by themselves—for instance, responses and requests and descriptions of each element in both. The other option is to write something by yourself that contemplates your API functions and endpoints and makes consistent documentation for you. Ultimately, there is an expanding amount of software tools that simplify and facilitate producing documentation.

But what distinguishes excellent documentation from adequate documentation is incorporating usage examples and, ideally, tutorials. It is what helps the peoples to know your API and where to begin. It aligns them and allows your API into their mind.

Once you complete your documentation, be sure to authenticate that it makes sense to users other than yourself. Then, share it with other developers in your team, give them no direction other than evincing them to the documentation, and tell them to build something fundamental or follow a tutorial in about 15 minutes. If they can’t have essential incorporation with your API in 15 minutes, you have more work to perform.

  1. Consistency and Stability:

If you have ever utilized Facebook’s web API Deployment, you will know how frequently they deplore and rewrite their APIs entirely. There is not a developer-friendly perspective no matter how much you respect their product and hacker culture. Their success story is that they got a billion users, not because their API is excellent. But you probably do not have the luxuriousness of such a massive market share and user base. So you will require a much less volatile API, maintaining old versions administering and supported for a considerable period.

For instance, plan something much ahead of that and version your API from the outset, clearly integrating a version number into the URL (http://myapisite.com/api/widgets/v1) or

(http://myapisite.com/api/widgets?version=1) so that users can rely on version 1. Then, they can update to any ensuing version when they are ready to do so.

An ideal URL scheme will include the leading versions in the URL. Therefore, any modifications to the supported data types or output format should knock up to a new main version. Typically, it is acceptable to maintain the same version if all you are performing is to add nodes or keys to your output but to be on the safer side, knock a version any time the output modifies.

In addition to that being steady over time, APIs required to be internally consistent. For example, multiple APIs modify parameter methods or the name of posting data based on the endpoint utilized. Instead, you should maintain standard parameters entirely within your API and use shared or inheritance architecture to recycle the same naming conventions and data consistently throughout your API. Lastly, you must record and publish a change log to reveal the contrast between your API versions so that people know exactly how to update.

  1. Flexibility:

GIGO (Garbage in, Garbage out) is a famous mantra to most programmers. As applied to web API deployment design, this guiding concept attempts a reasonable approach to request authentication. Sound effortless, right? Yes, no problem. But everything needs to be balanced as it is impossible to predict how people will wish to employ your service. Furthermore, not every client platform has a good platform and outstanding JSON support, a perfect OAuth library. Therefore, it is ideal to have a few tolerance or feasibility concerning your output and input constraints.

For instance, numerous APIs will support many output formats, such as XML, YAML, JSON, et al., but only help identify the URL’s design by itself. In the spirit of being feasible, you could also be identified in the URL (for example: /api.v1/widgets.json), or support a query string variable like ?format=JSON you might also view and acknowledge an accept: application/JSON HTTP header and so on.

And while we are at it, then why not permit for the format identified to be case-insensitive. Could the user identify? Format=json s well? That is an excellent example of a way to reduce unnecessary stress for the user of your API.

  1. Security:

Security is indeed one of the most crucial things to be constructed into your web API deployment service, but multiple developers make it hard to use. Thereforeyou should be offering all the usable examples of how to authorize and authenticate when accessing your API; undoubtedly, it is the API provider’s responsibility. It should not be a problematic issue that an end-user spends plenty of time working on it. Make it your aim that they either do not have to write any code or require less than 5 minutes to write the code.

The most preferred one for most of the APIs is a simple token-based authentication, where the taken is random assortment given to the user, and they can change it at any point if it has been robbed. Permit the token to be passed in through HTTP and POST header. For instance, the users must send an SHA-1 token as a header format such as ‘Authorization: da39a3ee5e6b4b0d3255bfef95601890afd8079’ or as a POST variable.

  1. Ease of adoption:

It is the most crucial rule in the bunch and constructs on all the others. As it is mentioned in the documentation step, attempt this with new users to your API. And ensure that they can get up and run with at least fundamental execution of your API, irrespective of just following a tutorial, within a few time. !5 minutes would be an optimal goal. To facilitate and ease up the adoption of your API, here are some recommendation

  • Ensure people can use your API and that it works smoothly the very first and every time.
  • Without doing any fancy authentication, maintain it in a simple form.
  • Offer language-specific libraries to connect with your service.
  • Simplify any essential signup
  • Offer excellent support


Web API deployment has always proven challenging to use. Of course, it might be due to multiple reasons like lack of documentation, poor design, unresolved rugs, and in the same cases, all of the above. But with the above information, it would be helpful to maintain your web API precisely so you can offer excellent security.
