Introduction

LinkedIn is the world's largest professional network on the internet. You can leverage LinkedIn to find the right job, connect with professionals within and outside of your career line and learn skills needed to transition into another career path, or become outstanding in your chosen career. LinkedIn can be accessed from any device with an internet connection. Optimizing Your LinkedIn profile can help you connect with opportunities all over the globe. Users can share their professional experience & skills, organize events, write articles, create learning content, search for jobs, post videos and photos, and more on LinkedIn.

With LinkedIn, business owners can grow their business through various means such as finding the right professional for a role, running marketing campaigns, content creation, etc. Job seekers can also tap into the network to connect with companies and hiring managers.

There are more than 830 million users in over 200 countries on LinkedIn. The platform also has over 57 million companies listed, with more than 15 million jobs listed.

Getting started with LinkedIn Jobs API

Proxycurl by Nubela makes tools for software engineers to build data-driven applications. You can think of Proxycurl as AWS for data-driven applications. It allows you to pull rich data about people and companies. With Proxycurl, you don't need to worry about scaling a web scrapping and data-science team for you to power your product with big data. Proxycurl offers a variety of endpoints: Person Profile API, Company Profile API, Work Email Lookup API, Employee Listing API, Reverse Email Lookup API, and Job API. Dwarf Forms, LinkDB, and Disposable Email Checker are other products by Proxycurl.

Proxycurl API is a set of tools designed to serve as plumbing for fresh and processed data in your application. It sits as a fully-managed layer between your application and raw data so that you can focus on building the actual application.

With Proxycurl API, you can:

  • Lookup people
  • Lookup companies
  • Enrich people's profiles
  • Enrich company profiles
  • Lookup contact information on people and companies
  • Check if an email address is of a disposable nature

Among the many Proxycurl APIs is the LinkedIn Jobs API that we shall be diving into in this article.

Proxycurl's LinkedIn Jobs API has two endpoints that you can use to list jobs and get a job profile:

Using these endpoints, you can collate a comprehensive list of jobs on LinkedIn, as well as get structured data of a job profile. The API response is usually in JSON format.

Uses of LinkedIn Jobs API

  • Build data-driven application: Proxycurl Jobs API enables developers to build and scale data-driven applications. Perhaps, you are a product-oriented person looking to build an application where job seekers can search for companies that have open positions and are hiring, this API empowers you to do this in real-time. You can make up to 300 API calls per minute.

  • Build and scale fast with ease. Build a working application in minutes. No worries about putting up a data science or web scrapping team. You need not crawl tens or even hundreds of job boards to gather job vacancies, rather, you will leverage Proxycurl Jobs API to get vacancies directly from hiring companies on LinkedIn.

  • Leverage on Data to perform specific tasks inside your application.

  • Get structured data of a LinkedIn job profile. Proxycurl Jobs API offers you structured data like apply_url, employment_type, industry job_description, seniority, location etc.

How to get access to LinkedIn Job API

Sign-up

On successful signup, you get this:

sign up successful

You have successfully created an account with Proxycurl and you have been credited with 10 credits to make API requests.

  • Next is to get you to the dashboard. Provide your email then click next to receive a magic link.

  • A magic link is sent to your mail for you to sign in with. This link takes you directly to your dashboard

  • Retrieve your API key from your dashboard. You are not authorized to make API request without your API key (Bearer token)

api key

You may add your card to begin topping up to avoid running out of credit.

  • Navigate the documentation to get the Jobs endpoint. This endpoint is what you make requests to.

Now that you have access to the Job API and also have an API key, you can now fetch jobs.

Fetching Jobs from the API.

Let's fetch jobs from the Job listing endpoint using JavaScript. You can do this in any language of your choice. I pick JavaScript because I love it and I'm most familiar with it 😉 🥰.

const api_endpoint = `https://nubela.co/proxycurl/api/v2/linkedin/company/job?search_id=${search_id}`
const api_key = 'YOUR_API_KEY'

fetch(api_endpoint, {
  method: 'GET',
  headers: {
    'Authorization': 'Bearer + api_key'
  }
})
.then(res => res.json())
.then(data => console.log(data))

The Job listing endpoint requires the search_id parameter to make a request. This is the only required parameter. You can get the search_id of a LinkedIn company via the Company Profile API.

We successfully made a request. Our response looks like this:

The endpoint returns an object having inside an array of job. The job array have objects containing company, company_url, job_title, job_url, list_date, and location. Other keys in the response are next_page_no, next_page_api_url, previous_page_no, and previous_page_api_url for navigating across pages.

The Jobs API costs 1 credit per successful request.

Let's also send a request to the Job Profile Endpoint to get structured data of a LinkedIn Job Profile.

const api_endpoint = `https://nubela.co/proxycurl/api/linkedin/job?url=${url}`
const api_key = 'YOUR_API_KEY'

fetch(api_endpoint, {
  method: 'GET',
  headers: {
    'Authorization': 'Bearer + api_key'
  }
})
.then(res => res.json())
.then(data => console.log(data))

Enter fullscreen mode Exit fullscreen mode

url is a required parameter for our request. This is the URL of the LinkedIn job profile to target.

The response looks like this:

    "apply_url": null,
    "company": {
        "logo": "https://media-exp1.licdn.com/dms/image/C4D0BAQHiNSL4Or29cg/company-logo_400_400/0/1519856215226?e=1661385600\u0026v=beta\u0026t=rUecQpduLPDavL3JswjLsJAUNgSu1Q2l3JS5sGp8nHk",

Limitation of LinkedIn Jobs API

Rate limit

Proxycurl allows you to make up to 300 requests per minute. You can make 1500 requests every 5 minutes.

When there is a high load of requests, Proxycurl might reduce rate limits for all accounts, this is to ensure that the services remain accessible for all users.

429 error code is returned when you are rate limited and when Proxycurl is capacity limited. 429 errors should be handled appropriately with exponential back-off applied.

Timeouts and API response time

Proxycurl API endpoints take an average of 2 seconds to complete. Concurrent requests to the API service are encouraged for maximizing throughput.
A timeout of 60 seconds is recommended.

Credits

Each valid request on Proxycurl requires at least 1 credit to be processed. Credit is deducted only if the request was successful

Proxycurl defines a successful request as a request that returns either a 200 or 404 HTTP status code. The latter is considered a successful request because resources were committed for the search but the profile was not valid

Conclusion

Leverage Proxycurl's LinkedIn Job API to get access to jobs posted by companies on LinkedIn. With this, you can build and scale data-driven applications within a short time.
