We have used POSTMAN to confirm a REST API call works to PingID PingOne. When using the REST API within Splunk, we see the connection occur, but compared to POSTMAN which returned a full response, the Splunk response was to return an empty JSON response.
We also tried a different REST API from Splunk to another server and confirmed the installation was correct.
We performed a CURL on the Splunk server and received a full JSON response.
Has anyone experienced this and/or provide suggestions for debugging?
