Micropython ESP8266 Twilio 401 UNAUTHORIZED

I'm running MicroPython on an ESP8266. The code should send an SMS HTTP POST request to Twilio's restAPI. I tried to get it working with urequests. but I keep getting a 401 UNAUTHORIZED response. Please some advise. The code:

import urequests

def send_sms():
    twilio_account_sid = "{AcctSID}"
    twilio_auth_token = "{AuthToken}"
    from_phn_nbr = "+{FromPhoneNbr}"
    to_phn_nbr = "+{ToPhoneNbr"))

    twilio_proto = "https://"
    twilio_host = "api.twilio.com"
    twilio_path = "/2010-04-01/Accounts/{AcctSID}/Messages"
    twilio_url = twilio_proto + twilio_host + twilio_path
    twilio_data = "'From': '{from_phn_nbr}', \
                  'To': '{to_phn_nbr}', \
                   'Body': 'Hai'"

    twilio_headers = {
        'Authorization': 'Basic {AcctSID}:{AuthToken}',
        'Content-Type': 'application/x-www-form-urlencoded',
        'WWW - Authenticate': 'Basic realm = "Twilio API'
    }

    try:
        resp = urequests.post(url=twilio_url, 
                                  data=twilio_data, 
                                  headers=twilio_headers)
        print(resp.status_code, resp.reason)

    except Exception as exc:
        print("\nException occured.")
        sys.print_exceptin(exc)

Using Postman:

  • Fill in tab Auth

enter image description here

  • Go to tab Headers
  • Copy 'Authorization' value

enter image description here

Past 'Authorization' value into your code like this:

twilio_headers = {
'Authorization': 'Basic QUMxMmZhNzFlYzU5MzZkNzYyMDYzNWM2Njg1NzNlZWNkNDo2OTBiY2Q5OTA2MDc3NmIzYmQ0NzgwOGE5ZTc2NmM5Yg==',
'Content-Type': 'application/x-www-form-urlencoded',
'WWW-Authenticate': 'Basic realm = Twilio API'

}

Twilio developer evangelist here.

I don't know the urequests library, but when using HTTP basic authentication it is not enough to simply concatenate the username, a colon, and a password. You need to base 64 encode that concatenated string too.

That's all I can think of from your implementation. Let me know if it helps.
