Hi
We are trying to Build a Form with user phone as one of the field, which on submission has to send SMS to user phone.

We are not able to trigger the External API, as it it keep saying the authentication failure.
External API works fine when we use Postman. Please advice how can we get external API  to get triggered  curl -L 'https://whatsapp.smart24x7.com/api/Whatsapp/SendTextMessage' -H 'clientId: AAAA' -H 'clientSecret: BBBB' -H 'Host: whatsapp.smart24x7.com' -H 'Content-Type: application/json' -d '{ "recipientPhoneNumber": "919811XXXXXX", "message": "your message here" }'
