SMS Gateway Configuration

Hello everyone,
I want to send sms reminders to ANC patients and I configured SMS gateway using Twilio as below

But when i send sms the server shows the following errors
is there anything I’m missing? i also tried configuring withOneSignal but it still fails

Hi @Resten_Madzalo

Please avoid showing authentication / sensitive info as this is a public forum. However, from what I see in the Key value pair, you’ve added the word “Basic” but are you sure that needs to be added instead of starting from “QUNIN…”?

The server uses basic authentication

I understand but does that require that you add the word itself?
