How do I send a flow to a user in a chat?

Once the flow is PUBLISHED (Meta Status = PUBLISHED), you can send it using a Flow message from your automation or API. In SMSGatewayCenter’s Workflow Builder, use the Send Flow message node: select the published flow, set the button text (e.g. “Book now”), and optionally header/body/footer. When the user receives the message and taps the button, the flow opens inside WhatsApp.
