How to scrape LinkedIn Ad with C#

Ad Details This tutorial gets it with a short C# program and the LinkedIn Ad API. Each successful call costs 1 credit; errors and not-found answers are free.

1. Get an API key

Sign in to get a key and 100 free credits, no card. Then put the key in an environment variable so it stays out of your code:

export SCRAPEIO_API_KEY="your_key_here"

2. Set up C#

dotnet new console -o scrape && cd scrape

3. Write the code

Save this as Program.cs. Replace PASTE_URL_HERE with a real url.

using System.Text.Json;

var http = new HttpClient();
http.DefaultRequestHeaders.Add("x-api-key", Environment.GetEnvironmentVariable("SCRAPEIO_API_KEY"));
var query = new Dictionary<string, string> { ["url"] = "PASTE_URL_HERE" };
string Url() => "https://scrapeio.com/v1/linkedin/ad" + "?" + string.Join("&", query.Select(p => $"{p.Key}={Uri.EscapeDataString(p.Value)}"));

var json = await http.GetStringAsync(Url());
var data = JsonDocument.Parse(json).RootElement.GetProperty("data");
Console.WriteLine(JsonSerializer.Serialize(data, new JsonSerializerOptions { WriteIndented = true }));

4. Run it

dotnet run

The response has the same envelope on every endpoint: success, cached, credits_used, credits_remaining and data. Shared fields such as handle, followers, plays, likes and created_at have the same names on every platform.

Parameters

Errors and what you pay

Same endpoint in other languages

Python · Node.js · JavaScript · TypeScript · Go · Rust · Java · PHP · Ruby · Kotlin · Swift · R

Prefer no code?

Connect the MCP server to Claude Code, Cursor or Codex and ask in plain English. The agent uses call_endpoint with path /v1/linkedin/ad for you.
