Illustrated in the image below is a Calculator step with the code that is used to generate a JWT Token. The value for the “payload” field can be any payload.
You can copy and paste the below code in your Calculator step:
let inputRecord=input.record;
let payload = {
}
let privateKey = fs.readFileSync('private.key')
inputRecord.jwt = utils.jwtSign(payload,privateKey, {"algorithm": "RS256"});
inputRecord.payload = payload;
return inputRecord;
