Avoid conversion on error in C# with HttpClient

In this guide, we'll show you how to avoid conversion on error using C# and the HttpClient library.

When converting documents to PDF, you might want to prevent conversion if certain errors occur to avoid generating invalid PDFs.

using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Threading.Tasks;

// You can get an API key at https://pdfshift.io
var apiKey = "sk_xxxxxxxxxxxx";

var client = new HttpClient();
client.DefaultRequestHeaders.Add("X-API-Key", apiKey);

var payload = new
{
    source = "https://www.example.com",
    // Prevent conversion on error
    continue_on_error = false
};

var json = System.Text.Json.JsonSerializer.Serialize(payload);
var content = new StringContent(json, System.Text.Encoding.UTF8, "application/json");

var response = await client.PostAsync("https://api.pdfshift.io/v3/convert/pdf", content);

// Handle errors:
if (response.StatusCode >= System.Net.HttpStatusCode.BadRequest)
{
    throw new Exception($"Request failed with status code {response.StatusCode}");
}

var result = await response.Content.ReadAsByteArrayAsync();

System.IO.File.WriteAllBytes("result.pdf", result);

Console.WriteLine("The PDF document was generated and saved to result.pdf");

This allows you to fail fast when conversion issues occur.

For further details on the continue_on_error property and its usage, please refer to our dedicated documentation.
