.sms
**SMS Settings**: Instructions and schema for defining SMS settings
SMS settings are defined under the sms key, as an object supporting the following properties:
app_settings.json .sms
| property | default | description |
|---|---|---|
| outgoing_service | medic-gateway | Defines the service to use to send SMS messages. Currently supports “medic-gateway”, “africas-talking” or “rapidpro”. For more information read the documentation on “africas-talking” configuration and “rapidpro” configuration. |
| duplicate_limit | 5 | The number of identical sms message allowed to be sent to the same recipient. |
Code sample
The definition takes the typical form below:
"sms": {
"outgoing_service": "medic-gateway",
"duplicate_limit": "2"
}Duplicate SMS messages handling
Every time a service (API or Sentinel) creates an SMS, we cache the recipient, and the message content, along with the current timestamp.
When more than duplicate_limit messages have been created for the same pair of recipient+content, within the cache time limit, we mark the new message with a “duplicate” status. Such messages are never sent.
The cache is cleared 30 minutes after the last SMS message for a specific pair was generated.
