Overview
The Wapisimo node's "Send Message" operation allows you to send WhatsApp messages via the Wapisimo API. This is useful for automating notifications, alerts, or direct communications to users through WhatsApp from your n8n workflows. Common scenarios include sending order confirmations, appointment reminders, or customer support messages.
Practical Examples
- Automatically notify customers when their order status changes.
- Send personalized reminders to clients about upcoming appointments.
- Alert team members of critical system events via WhatsApp.
Properties
| Name | Type | Meaning |
|---|---|---|
| Phone ID | String | The ID of the WhatsApp account to use for sending the message. |
| To | String | The recipient's phone number (the destination for the WhatsApp message). |
| Message | String | The content of the WhatsApp message to be sent. |
Output
The node returns the response from the Wapisimo API in the output's json field. The structure of this response depends on the Wapisimo API but typically includes information such as:
{
"status": "success",
"messageId": "abc123",
"to": "+1234567890",
"message": "Your message text here"
}
If an error occurs and "Continue On Fail" is enabled, the output will look like:
{
"error": "Error message describing what went wrong"
}
