Overview

This node interacts with the Wassenger WhatsApp API to manage WhatsApp groups. Specifically, the "Get Pending Members" operation under the "Groups" resource retrieves the list of members who have requested to join a specified WhatsApp group but are not yet approved.

This operation is useful in scenarios where you want to automate or monitor group membership requests, for example:

Automatically reviewing and approving pending group members.
Sending notifications or logging pending member requests.
Integrating group membership management into broader workflows such as CRM or customer support systems.

Properties

Name	Meaning
WhatsApp Number	The ID of the WhatsApp number (device) from which to query the group. This identifies the WhatsApp account used.
Group ID	The ID of the WhatsApp group for which to retrieve pending members. Examples: `447362053576-1500000000` or `447362053576-1500000000@g.us`.

Output

The output is a JSON object containing the data returned by the Wassenger API for the pending members of the specified group. This typically includes details about each pending member such as their contact information and request status.

The node does not output binary data.

Dependencies

Requires an API key credential for authenticating with the Wassenger WhatsApp API.
The node depends on the Wassenger service being accessible and properly configured.
The "WhatsApp Number" and "Group ID" must be valid and correspond to existing entities in the Wassenger system.

Troubleshooting

Invalid WhatsApp Number or Group ID: If the provided device or group ID is incorrect or does not exist, the API call will fail. Verify that these IDs are correct and loaded properly via the node's dropdown options.
Authentication Errors: Ensure the API key credential is correctly set up and has sufficient permissions.
Network Issues: Connectivity problems with the Wassenger API endpoint can cause failures; check network access and API availability.
Empty Pending Members List: If no pending members exist, the output may be empty or contain an empty array. This is expected behavior.
