KarFlows can deliver through multiple channels.

​
Supported channel IDs

​
Fallback delivery

Fallback mode tries channels in order and stops when one is accepted with a message ID.
Recommended for order alerts, booking confirmations, and OTP cost control. If a channel is not configured or ready, KarFlows records the failed attempt and continues to the next channel.

​
Send to all

All mode sends to every selected channel.
Recommended only when the message must arrive in multiple places. Each successful channel can be charged separately.

​
WhatsApp QR sender selection

If the customer has more than one QR device, pass whatsappFrom.
KarFlows validates that the sender belongs to the same customer account.

​
Meta sender selection

Meta sending uses the customer’s connected WhatsApp Business account. If a template is required, include the template data requested by your KarFlows Meta API setup. Outside Meta’s customer-service conversation window, provide metaTemplateName, metaTemplateLanguage, and any required metaTemplateParams.

​
SMS acceptance

SMS succeeds in routing when the delivery network accepts it and returns a message ID. Final delivery is asynchronous, so a later failed delivery report does not restart fallback.
