@blueblueskies I updated the gist you mentioned to add support for JWT. I made use of the JAVA library java-jwt and added support for SHA256withRSA. Example for PROC GROOVY: https://gist.github.com/FriedEgg/79ad315afa1b315e8ac3#file-sha256withrsa-jwt4sas-sas Github Repository for my fork of JAVA-JWT: https://github.com/FriedEgg/java-jwt and the JAR: https://github.com/FriedEgg/java-jwt/releases/download/java-jwt-2.1.2/java-jwt-2.1.1-SNAPSHOT.jar filename jwt '/path/to/java-jwt-2.1.2-SNAPSHOT.jar';
filename cp temp;
proc groovy classpath=cp;
add classpath=jwt;
