Interfaces and Responses

What are Communication Apps?
Communication Apps react to events triggered by Salla. Each event delivers a specific context object to your App Function, and your function is expected to return a structured response.

For App Functions fundamentals (execution types, Resp utility, runtime constraints, testing), see the App Functions reference.

Available events

The events your function receives are controlled by the Supported Features you declared in the Partner Portal.

Event	Fires when	Controlled by Supported Feature
`communication.sms.send`	Salla needs to send an SMS to a customer	Local SMS and/or International SMS
`communication.email.send`	Salla needs to send an email to a customer	Email
`communication.whatsapp.send`	Salla needs to send a WhatsApp message to a customer	WhatsApp
