Hi @Jarinek  I think you have to set -pv in front of the new value: nifi set-param -u http://localhost:8088 -pcid 85b8b5bf-0177-1000-3881-8ddd8d31fed8 -pn sample.URL -pv newvalue This one worked on my local NiFi. Remark: Haven't seen that you found it yourself. Great! ... View more

@GMAN  Here is my try to help you further. flow   Look at the picture of the InvokeHTTP. InvokeHTTP From my experience most options can mostly be left to default values. Your Json-body should be fine and will be send with the request. Remarks: - Authenticaton/Authorization: You have to try the two possibilities I know. For the second you have to add custom-property "Authorization" with the plus symbol on the right above. - Accept: Concerns the response format not sure wether you will need this.   Maybe you can first build your request in Postman and after successfull execution then click to "code" -> "HTTP". There you can see the details needed for the request.   In the "Settings" of the InvokeHTTP you can autoterminate the "original" flowfile. For "Retry" you can use the shown processor with default values. All "Failure" or "No retry" go to some error-handling. With "Response" you can go further in your flow.   Hope this helps you to come forward. ... View more
