This provider is an alternative to GpsGate SMS Proxy. It will accept incoming SMS over HTTP, and send outgoing SMS using an HTTP GET request. In this way you can easily make an integration to existing web services that provide SMS.

Outgoing SMS from GpsGate

GpsGate sends an SMS using the following HTTP GET request

Where "URL" is the url you specified when adding the "Message Provider" in step 7. above.

If the request to send an SMS fails the HTTP error code should be set. GpsGate will in that case try again every 15 minutes, and give up after 8 hours.
