Usage

Initialize the Client

All usage starts by calling the import command and initializing the client by passing your API key as a parameter to the constructor.

Api2PdfClient a2pClient = new Api2PdfClient("your-api-key");

Once you initialize the client, you can make calls like so:

Api2PdfResponse response = a2pClient.wkhtmlToPdfFromHtml('<p>test</p>', true, 'test.pdf');
String PdfUrl = response.getPdf();

Result Format

An ApiResult object is returned from every API call. If a call is unsuccessful then an exception will be thrown with a message containing the result of failure.

Additional attributes include the total data usage in, out, and the cost for the API call, typically very small fractions of a penny.

LibreOffice

LibreOffice supports the conversion to PDF from the following file formats:

• doc / docx
• xls / xlsx
• ppt / pptx
• gif

Merge PDFs from list of URLs to existing PDFs

String[] urls = new List<String>();
urls.add('http://www.orimi.com/pdf-test.pdf');
urls.add('http://www.orimi.com/pdf-test.pdf');
Api2PdfResponse pdfResponse = a2pClient.mergePdf(urls, true, 'test.pdf');
String pdfUrl = pdfResponse.getPdf();
