WassengerInstall

Overview

This node interacts with the Wassenger WhatsApp API to perform various operations related to WhatsApp messaging and management. Specifically, for the Labels resource with the Get Labels operation, it retrieves labels associated with a specified WhatsApp number (device). This is useful for organizing and categorizing chats or contacts within WhatsApp through labels.

Practical scenarios include:

• Fetching all labels assigned to a particular WhatsApp number to display or process them in workflows.
• Automating label-based filtering or routing of messages.
• Integrating label data into CRM or support systems for better contact management.

Properties

Output

The node outputs an array of JSON objects representing the labels retrieved for the specified WhatsApp number. Each object typically contains label details such as label name, ID, and possibly metadata depending on the API response.

If the node supports binary data output (not indicated here), it would represent any files or media related to labels, but for this operation, the output is purely JSON.

Example output structure (conceptual):

[
  {
    "id": "label_123",
    "name": "Support",
    "color": "#FF0000"
  },
  {
    "id": "label_456",
    "name": "Sales",
    "color": "#00FF00"
  }
]

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" property relies on dynamic loading of available devices via a method named getDevices.

Troubleshooting

• Common issues:

  • Invalid or missing API key credential will cause authentication failures.
  • Specifying a WhatsApp number that does not exist or is not linked to the account will result in errors or empty results.
  • Network connectivity problems can prevent successful API calls.

• Error messages:

  • Authentication errors: Check that the API key credential is correctly set up and valid.
  • "Device not found" or similar: Verify the WhatsApp number ID is correct and available.
  • API rate limits or service downtime: Retry after some time or check Wassenger service status.
