ApplinX REST API Response from XML to JSON

Product/components used and version/fix level:

Applinx 10.15

Detailed explanation of the problem:

I am unable to find the option where the REST API response is JSON, I have created a new Path Procedure and procedure group and copy REST URL to clipboard and check to see output in XML only.
I kind of did the same steps again but could not see a difference that gets response in JSON.

Please note that I am using Microsoft Edge to check the REST API output

Can you please point me to the place where I can see the option, that makes difference in REST API response from XML to JSON.

How to expose procedure as REST API that can return the output as JSON ?

I am able to expose procedure as rest API that can return the output as XML.

Error messages / full error message screenshot / log file:

when using headers Content-Type: applincation/json → HTTP 500 error.
When using Edge to see the response of URL, it works but the response is in XML.

Hello,

Please refer to the section “Executing a Procedure” under Using the ApplinX REST API

In case you are still getting errors invoking the procedure as JSON, please open a support call

Thanks,
Idan
