I have tried calling the Call-Out API with the body parameters, but I keep getting the same error every time.
I have attached my code snippet and the response for reference. I also tried using the deviceId (the relevant line is commented in the code), but the issue persists.
This is my code

This is response

Also checked in the documentation for this API but it is saying try with deviceId and tried with the deviceId then it will gives error for deviceId parameter value is inval.
My goal is to call the API using the from and to numbers. Could you please review and let me know why this gives me error this ?
Thanks.
