WhatsApi

Connect with WhatApp HTTP API

Actions29

Overview

This node integrates with a WhatsApp HTTP API to manage sessions. Specifically, the "Add Session" operation under the "Sessions" resource allows users to add or register a new WhatsApp session by providing a phone number. This is useful for automating WhatsApp interactions where establishing or managing sessions programmatically is required.

Practical examples include:

Automatically registering a new WhatsApp session when onboarding a user.
Managing multiple WhatsApp sessions in bulk via workflows.
Integrating WhatsApp messaging capabilities into broader automation processes.

Properties

No binary data output is indicated.

Dependencies

Requires connection to a WhatsApp HTTP API endpoint.
Needs an API authentication token or key configured in the node credentials.
The base URL for the API and authentication credentials must be set up in the node configuration.

Troubleshooting

Common issues:
- Invalid or missing phone number: Ensure the phone number is correctly formatted and provided.
- Authentication errors: Verify that the API key or token is valid and has necessary permissions.
- Network connectivity problems: Confirm that the API endpoint URL is reachable from the n8n instance.
Error messages:
- Authentication failures usually indicate invalid credentials; recheck API keys.
- Validation errors on the phone number suggest incorrect formatting or missing required fields.
- Timeout or connection errors imply network issues or incorrect API URLs.

Resolving these generally involves verifying input values, credentials, and network settings.
