What is OpenAPI description in github?

What is the difference between API and OpenAPI?

Today I was doing some work with the new OpenAPI 3.

0 standard and I thought about what exactly is the difference between an API description (typically used in backend systems) and an OpenAPI description (typically used in frontend systems).

From a REST architecture perspective the API description provides all the information about the operations available and the response format. It is typically used in backend systems where it is also only available via a web-service (and not in a human readable way on a file system). The OpenAPI specification provides additional info about the operations and parameters provided to the system and how the data is represented. It is typically used in frontend systems (that means web-services that you use on your mobile phone or desktop applications).

If I have the correct understanding of the difference between the two, it looks like you could go even further and differentiate the OpenAPI from the API. So this would mean that you would have the following (very simplified) descriptions of an API and an OpenAPI: /user/:id/post. POST. In this case the OpenAPI specification should be considered the real API and the API description is only a representation of the real API. If you look at the examples from OpenAPI, you can see that they actually do not specify what is the response code of the operation. You should only see the documentation for that from the backend system (as it will be the real source of truth).

So if you now consider using the OpenAPI specification for your frontend system, the API description would be just a documentation of the operations the backend system provides and what parameters the backend system accepts. Am I right in this understanding? It is a bit more complicated than that. But, I think you are almost there. There are three layers involved:
The API is a set of operations, parameters and responses. These are usually defined in a machine readable format.

The OpenAPI is a "contract" that specifies the operations, parameters and responses. APIs are usually implemented in a machine readable format. They don't include any contract.

APIs can also be "mockable". That is they can be defined as JSON files.

What is an API Blueprint?

API Blueprint is a way of documenting REST APIs.

It is not an end in itself but it provides a way to document and present the API. There are lots of tools to help you make an API Blueprint including some that use the API Blueprint format.

As with many things in life, it takes time to learn and get good at API Blueprint. I suggest that you start by reading the documentation (which is very good) and then look at other examples of API Blueprint to see how they are written. In time you will get used to writing API Blueprint and will feel more confident.

The purpose of this article is to explain what API Blueprint is and some of the basic concepts of how to make a good API Blueprint. I suggest you read all of this article before you start writing your first API Blueprint. I think it is important to read all of it as it will give you some understanding of what is going on. If you understand these things before you start writing you are more likely to make progress and be successful.

I suggest that you do the following: Make sure you have the latest version of API Blueprint (Version 1.0 as of the date of writing this article).

Make a text file called api-blueprint.txt. You can make this file in any text editor you like.

If you don't already have a website for your API then you need to set this up. I suggest that you look at my articles on how to build a simple website for free. I wrote an article on how to set up your development environment. It is important that you have a place to test your API.

The main sections of this article are: ? What do I mean by an API Blueprint? Why do we need an API Blueprint? What does an API Blueprint look like? What is a path? What is an endpoint? What is a resource? How do I make a GET request? What is a response? What are the different sections of an API Blueprint? An API Blueprint is a specification of an API. It provides a way to communicate the details of an API and describe how it operates. The process of making an API Blueprint means that we tell the world what an API is and how it works.
