Accessing the OLX Public API Using JavaScript

The OLX public API allows developers to access a variety of data from OLX, including listings, users, and categories. In this blog post, we will learn how to access the OLX public API using JavaScript.

Getting Access to the API

Before we start accessing the OLX public API, we need to obtain an API key. To get an API key, we need to create an account on developer.olx.pl, and then follow the instructions listed on this page.

After we have obtained an API key, we can start accessing the OLX public API.

Connecting to the API

To connect to the OLX public API using JavaScript, we need to make an HTTP request to the API endpoint. We can use the fetch() function to make the request.

Here is an example code that shows how to connect to the categories API endpoint:

const API_KEY = "YOUR_API_KEY";
const API_BASE_URL = "https://api.olx.pl/v1";

fetch(API_BASE_URL + "/categories", {
  headers: {
    Authorization: `Bearer ${API_KEY}`
  }
})
  .then(response => response.json())
  .then(categories => console.log(categories));

In this example code, we set the API_KEY variable to our OLX API key, and API_BASE_URL variable to the base URL of the OLX API.

We then use the fetch() function to send an HTTP GET request to the /categories endpoint of the OLX API. We also pass our API key as an Authorization header in the request.

When we receive a response from the API, we convert it to JSON format using the json() method, and then log the categories to the console.

Accessing Listings

Once we have connected to the OLX API, we can start accessing its data. Let's take a look at an example code that shows how to access listings from the API:

const API_KEY = "YOUR_API_KEY";
const API_BASE_URL = "https://api.olx.pl/v1";

fetch(API_BASE_URL + "/offers", {
  headers: {
    Authorization: `Bearer ${API_KEY}`
  }
})
  .then(response => response.json())
  .then(listings => console.log(listings));

In this example code, we send an HTTP GET request to the /offers endpoint of the OLX API, and then log the listings to the console.

Conclusion

In this blog post, we have learned how to access the OLX public API using JavaScript. We learned how to connect to the API, and how to access listings data. You can use these examples as a starting point to build your own OLX API-powered application.
