We can use the Pega OOTB Code-Pega-PDF.View activity along with Java code to achieve this.
- In your activity which is calling API on click of button, add 3 more steps after you fetch base64 string.
- Set 2 Params.
- PDFName = "MyPDF"
- PDFB64 = Base64 String of PDF received from API
- Call below Java code to convert Base64 code to ByteArray
- Call Code-Pega-PDF.View Activity.
Code to Convert Base64 to Byte Array:
String fileb64 = tools.getParamValue("PDFB64").toString(); //Set value from Param
byte[] byteArray = new com.pega.pegarules.pub.util.Base64Util().decodeToByteArray(fileb64);
tools.putParamValue("PDFDocument",byteArray);
