Overview
The WhatsApp "Send Message" operation in this Wasapi integration node allows users to send text messages via the Wasapi API. This node is useful for automating outbound WhatsApp communications such as customer notifications, alerts, or marketing messages. For example, a business could use it to automatically send order confirmations or appointment reminders to customers.
Properties
| Name | Meaning |
|---|---|
| Message | The text content of the message you want to send. |
| Phone Wasapi Name or ID | Select the phone number associated with your Wasapi account from a list or specify its ID via expression. |
| WhatsApp ID | The recipient's phone number including country code but without the "+" sign (e.g., 573203294920). |
Output
The node outputs JSON data representing the response from the Wasapi API after attempting to send the message. This typically includes information about the message status, any errors, and metadata related to the sent message. There is no indication that binary data is output by this node.
Dependencies
- Requires an active Wasapi API account with valid credentials configured in n8n.
- Needs the Wasapi API key credential set up in n8n to authenticate requests.
- The node uses Wasapi’s REST API endpoint at
https://api-ws.wasapi.io/api/v1.
Troubleshooting
- Common issues:
- Invalid or missing API credentials will cause authentication failures.
- Incorrectly formatted WhatsApp IDs (missing country code or including "+") may result in message delivery errors.
- Selecting a phone number not linked to your Wasapi account can cause request failures.
- Error messages:
- Authentication errors usually indicate invalid API keys; verify and update credentials.
- Validation errors on the WhatsApp ID suggest formatting issues; ensure the number is numeric and includes country code without "+".
- Network or API downtime errors require checking Wasapi service status or network connectivity.
