Overview

This node operation checks if a given phone number or JID (Jabber ID) is registered on WhatsApp using the WasenderAPI. It is useful for verifying the existence of a contact on WhatsApp before attempting to send messages or perform other contact-related operations. For example, a user can input a phone number to confirm if it is active on WhatsApp, helping to avoid sending messages to invalid contacts.

Use Case Examples

  1. Verify if a phone number is registered on WhatsApp before sending a message.
  2. Check the WhatsApp status of a contact's JID to validate contact information.

  • jid - The Jabber ID of the contact checked.

Dependencies

Troubleshooting

  • Ensure the session ID or auto-selected session is correctly provided; otherwise, the node will throw an error indicating a missing session.
  • The phone number or JID must be correctly formatted; invalid formats may cause the API request to fail.
  • If the API returns errors like 408, 429, 500, 502, or 503, the node can retry the request based on the retry options configured.
