How To Make Api Calls

Posted on  by admin

By keeping all the endpoints in globally shared file. While developing a web application, we have to make some APIs calls in order to get or update the data we are using. Usually, the calls are called directly into the code, for example. That is a classic snippet where, by using the well know library axios, we are making an API call directly into the component code.

It may happen that in another file we need to do the exactly same request so we just use the same code. Usually, developers love copy and paste.

What is an API Call?

This a common situation with redundant code. So if something change in the server, we need to update two functions in two files: that is inconvenient. Easily, a correct thing to do is to create a file, called api.js where we store a big object with all the endpoints URLS.

And similarly in the other file. Now if we want to change the url, we can just edit one file.

Anatomy of REST:

But, still, we have some shared code: the axios call. Let’s actually move all the logic behind calling our web server into the shared file. Now we can just call api.posts('posts').getAll() in our code.

REST Client:

We can now even expand solution#2 by creating an API class that will create the basic CRUD endpoints for us.

You can find the code here:. We can now easily create an API instance.

And then create all the correct handles for the posts entity with one line of code. Let’s try if it works! I have a web quote API running at localhost:8080/api/posts.

Let’s try to fetch one by id. We can also try to create/update and delete a post. Now check the server’s logs.

Everything worked as expected. We have successfully create our endpoints for the posts entity. We have seen how we can improve our application’s code by just sharing global data into a global file.

Get that jargon away

We have seen some solution about the problem and how to automatically create APIs call by using a util class.

I hope you like this article, let me know your feedbacks. Thank you for reading. Francesco Saverio Zuppichini. This is WePay’s API reference site, which contains a full index of WePay’s API and how to integrate with it.

Every call must include an access_token, which is unique to each user-application pair.

Some calls require client_id and your client_secret. All responses are shown in JSON. Access to the WePay API is granted when you register your application.

WePay recommends that you integrate in our stage environment before registering for production access. We strongly recommend using one of our SDKs to make API calls.

If you’re using a language that’s not supported by one of our SDKs, you’ll have to learn how to construct an API call yourself.

First, decide which API Endpoint (base URL) you want. Then pass the appropriate access_token as an HTTP header with the following form, where abc123 is the access token:.

Call arguments should be passed as JSON in the body of the request with content-type HTTP header set to application/json.

Make sure to set a valid User-Agent header (our SDKs do this for you).

So tell me now, how does REST look?

The User-Agent can be anything, but keep it informative. For example: “WePay v2 PHP SDK v0.0.9”. If you’re using PHP, you can use PHP’s libcurl functionality to make calls.

For example, below is a call to /v2/user (no required parameters). APIs, short for Application Programming Interfaces, are software-to-software interfaces. Meaning, they allow different applications to talk to each other and exchange information or functionality.

This allows businesses to access another business’s data, piece of code, software, or services in order to extend the functionality of their own products — all while saving time and money.

Now that you understand the benefits, you might be wondering how you can exactly use an API to request and get data from another application.

That’s where API calls come in. An API call is the process of a client application submitting a request to an API and that API retrieving the requested data from the external server or program and delivering it back to the client.

How to Make API calls

Let’s say your app uses Facebook APIs to extract data and functionality from the platform. In that case, when broadcasting a live Facebook video stream, creating a post, or building a custom dashboard for your ads, you are actually making an API call.
