Appointment reminder — WhatsApp

SETUP: add a “whatsapp” credential in Admin → Credentials, then Test sends for real — the node is pre-wired with ${credential.…} references. Until then this demo saves and verifies but the send will report the missing credential. Reminds the customer a day ahead via the WhatsApp Business API.

What’s inside

3 nodes — every type links to its full reference page.

Step	Node	Type
Upcoming appointment	Inject	`input.inject`
Send reminder	WhatsApp	`output.whatsapp`
Sent	Console	`utility.console`

Import it

Studio → Import — paste the JSON below (or the URL /docs/templates/appointment-reminder-whatsapp.json).

Or ask the AI Copilot with the JSON pasted after the phrase:

import this workflow json into a new workflow named "Appointment reminder — WhatsApp"

Any credentials the nodes need are ${credential.…} references — add them once in Admin → Credentials and the template picks them up. Nothing secret ships in a template.
