.registrations

**Registrations**: Defining SMS workflows with schedules, registration, and patient reports.

The registrations key contains actions that need to be performed for incoming reports of the specified form.

`app_settings.json .registrations[]`

property	description	required
`form`	Form ID that should trigger the schedule.	yes
`events`	An array of event object definitions of what should happen when this form is received.	yes
`event[].name`	Name of the event that has happened. The only supported event is `on_create` which happens when a form is received.	yes
`event[].trigger`	What should happen after the named event. `assign_schedule` will assign the schedule named in `params` to this report. Similarly `clear_schedule` will permanently clear all messages for a patient or place that are part of schedules listed in the `params` field. The full set of trigger configuration directives are described here.	yes
`event[].params`	Any useful information for the event. In our case, it holds the name of the schedule to be triggered.	no
`event[].bool_expr`	A JavaScript expression that will be cast to boolean to qualify execution of the event. Leaving blank will default to always true. CouchDB document fields can be accessed using `doc.key.subkey`. Regular expressions can be tested using `pattern.test(value)` e.g. /^[0-9]+$/.test(doc.fields.last_menstrual_period). In our example above, we’re making sure the form has an LMP date.	no
`validations`	A set of validations to perform on incoming reports. More information about validation rules can be found here.	no
`validations.join_responses`	A boolean specifying whether validation messages should be combined into one message.	no
`validations.list[]`	An array of validation rules a report should pass to be considered valid.	no
`validations.list[].property`	Report field for which this validation rule will be applied.	no
`validations.list[].rule`	Validation condition to be applied to the property field. More information about rules can be found here.	no
`validations.list[].translation_key`	Translation key for the message reply to be sent if a report fails this rule.	no
`messages`	An array of automated responses to incoming reports.	no
`messages[].translation_key`	Translation key for the message text associated with this event.	no
`messages[].event_type`	An event that will trigger sending of this message. Typical values are: `report_accepted` when the report has been successfully validated and `registration_not_found` when the shortcode (patient ID or place ID) supplied in the report doesn’t match any shortcode issued by Medic.	no
`messages[].recipient`	Who the message should be sent to. Use `reporting_unit` for the sender of the report, `clinic` for clinic contact, and `parent` for the parent contact. See SMS Recipients	no
