Wappfy

Interact with WhatsApp through Wappfy API

Overview

This node enables interaction with WhatsApp contacts through the Wappfy API, specifically allowing you to unblock a contact. Unblocking a contact removes any previous block status, enabling communication again. This is useful in scenarios where you have previously blocked a contact and want to restore messaging capabilities without manually doing so in the WhatsApp app.

Practical example:

  • You accidentally blocked a contact and want to programmatically unblock them to resume conversations.
  • Automate unblocking contacts based on external triggers or workflows, such as customer support systems or CRM integrations.

Properties

Name Meaning
Contact ID The unique identifier or phone number of the contact to unblock

Output

The node outputs JSON data representing the response from the Wappfy API after attempting to unblock the specified contact. The structure typically includes confirmation of the unblock action or details about the contact's updated status.

If multiple items are processed, the output is an array of JSON objects corresponding to each input item.

No binary data output is involved in this operation.

Dependencies

  • Requires an active Wappfy API credential with a valid API key and instance name configured in n8n.
  • The node makes HTTP requests to the Wappfy API endpoints.
  • Network access to the Wappfy API base URL is necessary.

Troubleshooting

  • Common issues:

    • Invalid or missing Contact ID: Ensure the Contact ID or phone number is correctly provided and formatted.
    • Authentication errors: Verify that the API key credential is correctly set up and has sufficient permissions.
    • Network connectivity problems: Confirm that the n8n instance can reach the Wappfy API endpoint.
  • Error messages:

    • Errors returned by the API will be included in the node output if "Continue On Fail" is enabled. Otherwise, the node execution will stop with an error message.
    • Typical errors include "Contact not found," "Unauthorized," or "Invalid session." Check credentials and input parameters accordingly.
