Usage

Getting started

The quickest way to get started is to first get a set of API keys here and run the following code snippet:

public_key  = 'YOUR_PUBLIC_KEY'
private_key = 'YOUR_PRIVATE_KEY'
ilovepdf = Ilovepdf::Ilovepdf.new(public_key, private_key)
# Create a task with the tool you want to use:
task = ilovepdf.new_task :compress
# Add the files you want to upload...
file1 = task.add_file 'my_disk/my_example1.pdf'
file2 = task.add_file 'my_disk/my_example2.pdf'
file3 = task.add_file_from_url 'http://URL_TO_PDF'
# Once you are done uploading your files:
task.execute
task.download

That's it!

For a more in-depth usage, refer to the sample codes in this repository.

Documentation

HTTP API Calls

All PDF tools have the following methods that contact with the iLovePDF API:

Method Description Notes
add_file(file) Uploads a file to iLovepdf servers Returns boolean
add_file_from_url(url) Uploads a file to iLovepdf servers using a URL Returns boolean
delete_file(file) Deletes a file from ilovepdf Returns boolean
download(filepath) Downloads the processed file Returns boolean; No need to specify a filepath
status Retrieves the current status of the task being processed Returns Ilovepdf::Response
execute Sends a request to Ilovepdf to begin processing the PDFs Returns Ilovepdf::Response
delete! Deletes the task Returns Ilovepdf::Response

Example:

imagepdf_task = Ilovepdf::Tool::Imagepdf.new(public_key, secret_key)
http_response = imagepdf_task.execute
puts http_response.body
if imagepdf_task.download
  puts "Your file was downloaded successfully!"
end

Methods common to all tools

Method Description Notes
enable_file_encryption(boolean, key) The key will be used to decrypt the files before processing and re-encrypt them after processing If no key provided, a random key is assigned (default: false)
assign_meta_value(key, value) More info
ignore_errors More info (default: true)
ignore_password More info (default: true)
try_pdf_repair When a PDF to process fails we try to repair it automatically (default: true)
packaged_filename This allows you to specify the filename of the compressed file in case there is more than 1 file to be downloaded
output_filename The final name of the processed file

Methods to query after performing the execute API method:

  • result: It has stored the last Ilovepdf::Response

Methods to query after performing the download API method:

  • download_info: Returns a struct with the following info
    • :output_filename
    • :output_file
    • :output_filetype

Tool attributes

All tools have specific attributes you can access and modify. If you need want to know which params are available for a specific tool via the code, you can by looking at the API_PARAMS of that particular tool. For example for the Image to PDF tool:

puts Ilovepdf::Tool::Imagepdf::API_PARAMS
# => [:orientation, :margin, :pagesize]

To instantiate a Compress tool task directly do:

compress_task = Ilovepdf::Tool::Compress.new(public_key, secret_key)

Handling errors

Whenever there is an API Error in one of the endpoints, you can try to capture it the following way:

begin
  compress_task = Ilovepdf::Tool::Compress.new(public_key, secret_key)
  compress_task.execute # Oops, this raises an error! I forgot to upload a file!
  compress_taks.download
rescue Ilovepdf::ApiError => e
  # Let's check what went wrong with the API call:
  puts e.http_response.body
end

For a more complete example of error handling check samples/try_catch_errors.rb
