PDF Generation API in Ruby
Complete Ruby integration guide for the PDF Generation API. Copy the code below, add your RapidAPI key, and start building.
Prerequisites
- 1.Sign up for a free account on RapidAPI
- 2.Subscribe to the PDF Generation API (free tier available)
- 3.Copy your
X-RapidAPI-Keyfrom the dashboard - 4.Install the dependency:
gem install httparty
Complete Ruby Example
require "httparty"
require "json"
url = "https://pdf-generation-by-helix-api.p.rapidapi.com/from-html"
headers = {
"Content-Type" => "application/json",
"X-RapidAPI-Key" => "YOUR_API_KEY",
"X-RapidAPI-Host" => "pdf-generation-by-helix-api.p.rapidapi.com"
}
body = {"html": "<h1>Hello from Helix-API</h1><p>PDF generation works.</p>"}
response = HTTParty.post(url, headers: headers, body: body.to_json)
data = JSON.parse(response.body)
puts "Status: #{data['status']}"
puts "Result: #{data['data']}"Response Format
All Helix-API endpoints return a consistent JSON envelope:
{
"status": "ok",
"data": { ... },
"meta": {
"request_id": "req_abc123",
"latency_ms": 42
}
}On errors, status becomes "error" and a message field explains what went wrong.
Error Handling
| Status | Meaning | Action |
|---|---|---|
200 | Success | Parse the response body normally |
400 | Bad request | Check your request parameters |
401 | Unauthorized | Verify your X-RapidAPI-Key header |
429 | Rate limited | Wait and retry with exponential backoff |
500 | Server error | Retry after a short delay |
Ruby Best Practices
HTTParty keeps it simple
HTTParty is the most popular Ruby HTTP library. One gem install and you're calling the PDF Generation API in 5 lines.
Rails integration
Wrap the API call in a service object (app/services/helix_api.rb). Use Rails.cache.fetch for caching.
Faraday for advanced use
For middleware support (retries, logging, caching), use Faraday instead. It's the standard for production Ruby API clients.
Handle timeouts
Set a timeout option in your HTTP calls. HTTParty supports timeout: 10 to prevent hanging requests.
