Issue with Hitman

What is the issue?
When I try to run any API on Hitman, try pe click karne k baad processing hoti rehti hai…not giving any results.

What was the expected behaviour according to you?
It must have submitted my request and generated the request ID. Cross verified it on postman and it worked correctly.

Steps to replicate?
Try to run send SMS via flow docs.msg91.com

Just gave it a try and it looks perfect at my end.
Got the response { “message”: “5e1e93cad6fc054d8e759a5b”, “type”: “success” } for the endpoint: Hitman

Can we connect for an online session to check the same at your end?
