Nifi InvokeHttp Content-Type with GET

[#1]

The web service I'm calling requires the Content-Type header to be set to application/json, but it appears the InvokeHttp processor only sets this header if it is a POST or PUT request. Is there any way to set this header for GET requests?

Have you looked at adding a dynamic property? If you take a look here: https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi.processors.standard.InvokeHTTP/

"Attributes to send" is where you will want this. So in your nifi processor it should look like the image attached, can you try that?

Thanks for the answer. What you posted didn't work, but I did play with and eventually got it. What I had to do was have an UpdateAttribute processor before my InvokeHTTP that sets an attribute called "Content-Type", then in InvokeHTTP, set "attributes to send" to "Content-Type" and it worked.

Thanks!

Do you know how to retrieve the content type from the message properties when using ConsumeJMS?
