Requirements

• RapidSMS, version 0.14.0 or later

  (pip install ‘rapidsms>=0.14.0’)

• Django, version 1.4 or later.

Usage

Create an application at tropo.com. Its type should be “Web API”.

Add rtropo to your Python path and set up the Tropo backend in your Django settings file.

The required settings for your Tropo backend in INSTALLED_BACKENDS are:

ENGINE

“rtropo.outgoing.TropoBackend”

config

A dictionary with the rest of your settings for this backend. Required settings inside config are:

messaging_token

Your messaging token from Tropo (a long hex string)

number

The phone number your Tropo app is using. Must start with “+” and the country code.

For example:

INSTALLED_BACKENDS = {
    "my-tropo-backend": {
        "ENGINE": "rtropo.outgoing.TropoBackend",
        'config': {
            # Your Tropo application's outbound token for messaging (required)
            'messaging_token': 'YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY',
            # Your Tropo application's voice/messaging phone number, starting
            # with "+" and the country code (required)
            'number': '+1-###-###-####',
        },
    },
}

At this point you should be able to send outgoing messages, but more setup is needed to receiving incoming messages.

Set up your URLconf to send incoming http requests from tropo to rtropo.views.message_received, passing the backend_name parameter, whose value must be the same as the backend name you used in INSTALLED_BACKENDS.

For example:

from django.conf.urls.defaults import *
from rtropo import views

urlpatterns = patterns('',
    url(r"^tropo/$",
        views.message_received,
        kwargs={'backend_name': 'my-tropo-backend'},
        name='tropo'),
)

You can use any URL. If you want to add some (slight) protection against someone other than Tropo passing you messages pretending to be Tropo, you might make your URL long and random, e.g.:

from django.conf.urls.defaults import *
from rtropo import views

urlpatterns = patterns('',
    url(r"^534bd769-3e2e-42bd-8337-2099d9f38858/$",
        views.message_received,
        kwargs={'backend_name': 'my-tropo-backend'},
        name='tropo'),
)

Configure your Tropo application at tropo.com so its SMS/Messaging URL will invoke the Django URL that you just configured. E.g.:

https://yourserver.example.com/534bd769-3e2e-42bd-8337-2099d9f38858/
