Ruby on Rails Barcode Integration: Background Jobs and Attachment Strategy

Rails barcode workflows are usually cleaner when the request creates a job record, a background worker renders the asset, and the result is attached or streamed only after validation passes. This avoids tying controller latency to image generation and document packaging.

response = Faraday.get("https://api.barcode-generators.com/v1/generate", {data: payload, type: "code128", format: "svg"}) do |req|
  req.headers["Authorization"] = "Bearer YOUR_API_KEY"
end
File.write("label.svg", response.body)
