Overview

This node interacts with the Wassenger WhatsApp API to perform various operations related to WhatsApp groups. Specifically, the "Get Group" operation under the "Groups" resource retrieves detailed information about a specific WhatsApp group associated with a selected WhatsApp number.

Common scenarios where this node is beneficial:

Fetching metadata or details of a particular WhatsApp group for monitoring or reporting.
Integrating WhatsApp group data into CRM or customer support systems.
Automating workflows that depend on group information, such as member management or message broadcasting.

Practical example:

A user wants to retrieve the details of a customer support group linked to a specific WhatsApp number to display group info in their dashboard or trigger further automation based on group attributes.

Properties

Name	Meaning
WhatsApp Number	The ID of the WhatsApp number to use (e.g., a phone number registered with WhatsApp). This is required and selectable from available devices.
Group ID	The ID of the WhatsApp group to retrieve information about. Examples include IDs like `447362053576-1500000000` or `447362053576-1500000000@g.us`. This is required and depends on the selected WhatsApp number.

Output

The node outputs JSON data representing the details of the specified WhatsApp group. This typically includes group metadata such as:

Group ID
Group name
Participants list
Group description
Other relevant group attributes provided by the Wassenger API

No binary data output is indicated for this operation.

Dependencies

Requires an active connection to the Wassenger WhatsApp API.
Needs an API key credential configured in n8n for authentication with the Wassenger service.
The node dynamically loads options for WhatsApp numbers and groups via internal methods, which rely on the API.

Troubleshooting

Common issues:
- Invalid or missing WhatsApp number or group ID may cause errors.
- API authentication failures if the API key is incorrect or expired.
- Network connectivity problems preventing access to the Wassenger API.
Error messages and resolutions:
- "Group not found" — Verify the Group ID is correct and belongs to the selected WhatsApp number.
- "Authentication failed" — Check that the API key credential is valid and properly configured.
- "Failed to load options" — Ensure the WhatsApp number has been correctly set and the API is reachable.
