approxy is a custom proxy service that presents a webhook for the NGtrend SMS aggregator and then translates the request into one that Apollo understands.

NGtrend usually makes a HTTP POST request to the chosen endpoint with a form with the parameters: msg for the contents of the text message and tel for the sender phone number. They also expect an xml-encoded response as the reply.

Apollo on the other hand would take HTTP GET parameters: sender for the sender, text for the contents of the text message and secret for the custom messaging secret used to authenticate valid requests.

Usage: approxy [-p <port>] -u <url> -s <secret>

Options:
  -p, --port        listening port (default: 3030)
  -u, --url         base url for Apollo service
  -s, --secret      messaging secret
  --help            display usage information
