hi @nirshani, We had implemented Twilio SMS at our end and during the process realized that we were unable to accomplish sending sms/whatsapp message directly using custom action as twilio uses basic authentication with content type as url encoded.The combination of which is currently not available/...

@iamromioghosh - The custom action authentication didn't seem to work for us for Content Type as url encoded though the test was successful and so we had to resort to Adobe IO to do the API calls.

HI @d_G_n111 , Were you able to overcome this error that you were encountering. We are also facing a similar error and your inputs if any would be of great help.
