@bhardwajaditya please add logging that shows exactly what is in the call we make to twilio.

• Include all the parameters...... twilio team has suggested that they are only getting the to and from fields.
• Since we use the twilio library method client.messages.create() it could be possible that the library is not accepting our extra params. Is there a logging function upon POST that we can use to see exactly what it is sending.

@bhardwajaditya Looking again at the twilio docs it seems that they are showing a way to log what the twilio library is doing by using the .then() part?

client.messages
.create({
contentSid: 'HX...XXX',
from: 'MG...XXX',
contentVariables: JSON.stringify({
1: 'Name'
}),
to: 'whatsapp:+18551234567'
})
.then(message => console.log(message.sid));

FYI - in regard to the twilio nodejs library, the rep sent me this link for modifications: https://github.com/twilio/twilio-node/blob/main/advanced-examples/custom-http-client.md
