Please let me know if I am missing anything here

Did you try changing application/json to text/plain in your parameters?

You need to format the body as application/x-www-form-urlencoded.

Change the Content-Type to Custom - application/x-www-form-urlencoded

and pass the body like: 

"To=%2BPhoneNumber&From=%2BPhoneNumber&Body=Hi%20Dear"

Also, make sure that you have verified the number you are using in "To" from Twilio Console. 

Technically, it accepts both multipart/form-data and application/x-www-form-urlencoded.

From the docs:

Twilio's APIs expect the content type of API requests to be either application/x-www-form-urlencoded or multipart/form-data. It is important to note that although Twilio returns responses in JSON format, the API requests themselves should be formatted as either www-urlencoded or multiparty form data.

yeah - it's there in the docs. But multipart/form-data didn't worked for me as well and hence I tried application/x-www-form-urlencoded which eventually worked. Later, I also found multiple posts on stack overflow stating that it only accepts application/x-www-form-urlencoded.

Hi..It worked with multipart/form-data as well. The way I was passing data was wrong initially .

the correct way is as below:
