izapp - WhatsAppInstall

Overview

This node integrates with a WhatsApp-based customer relationship platform, enabling various operations related to contacts, protocols, messages, groups, marketing campaigns, and more. Specifically, the "Protocolo - Mensagem - Listar" operation retrieves all messages associated with a given service protocol number. This is useful for scenarios where you want to fetch the conversation history or message log tied to a particular customer support or service protocol.

Practical examples include:

• Retrieving all messages exchanged under a specific support ticket to analyze communication.
• Displaying message history in dashboards or reports.
• Automating follow-up actions based on message content or status within a protocol.

Properties

Output

The node outputs JSON data containing the list of messages linked to the specified protocol number. Each item in the output array represents a message with details such as sender, timestamp, content, and possibly message status or metadata depending on the platform's API response.

If the node supports binary data output (not explicitly shown here), it would typically represent media attachments or images related to messages.

Dependencies

• Requires an API key credential for authenticating with the external WhatsApp-based customer relationship platform.
• The node depends on internal action modules that handle API calls for each operation.
• Proper configuration of the API credentials in n8n is necessary for successful execution.

Troubleshooting

• Missing or invalid protocol ID: Ensure the "ID Do Protocolo" property is provided and correctly formatted; otherwise, the API call may fail or return no data.
• Authentication errors: Verify that the API key credential is valid and has sufficient permissions.
• Empty message list: If no messages are returned, confirm that the protocol number exists and has associated messages.
• API rate limits or connectivity issues: Network problems or API throttling can cause failures; check logs and retry accordingly.
