Any help or insight into where things are going wrong would be appriciated

  • Hi @Zeak, in the settings you have a different url as test. The settings URL starts with platform and te thest url starts with api. Why? Dec 18, 2017 at 12:29

As per Clickatell api documentation the api url to send sms is https://platform.clickatell.com/messages/http/send?apiKey=xxxxxxxxxxxxxxxx==&to=xxxxxxxxxxx&content=Test+message+text

Please cross check in clickatell the api key under SMS Integration tab(it should be of 24 chars with '==' at the end).
