I am attempting to use TRESTClient/REST Debugger to get the User ID and token from a Joomla website.
The url is as follows:
For the Login API Call Please provide the Username and password in the API request body - https://thesite.com/index.php?app=users&resource=login&option=com_api&format=raw
The request must contain 2 values:
- key-> username, value-> exampleUser
- key-> password, value-> xyz
I am failing to get the correct response. I am able to get results from other resources from the same website, but this I am only getting an empty body.

You need to change the parameter type of the username and password parameter to BODY instead of GET/POST. This will place them into the request body instead of the URL.
