Overview

This node interacts with the Go WhatsApp Web MultiDevice API to check contact information for a user based on their phone number. It is useful in scenarios where you need to verify or retrieve details about a WhatsApp contact, such as confirming if a phone number is registered on WhatsApp or fetching related user information.

Use Case Examples

  1. Checking if a phone number is a valid WhatsApp contact before sending a message.
  2. Retrieving contact details for a user phone number to display in a CRM system.

Properties

Name Meaning
Device ID Optional device ID override that takes priority over the credential device ID if set.
User Phone Phone number to get info for; leave empty to get info for the authenticated user's own phone number.

Output

JSON

  • contactStatus - Status or result of the contact check operation
  • contactDetails - Details about the contact if available, such as name, profile info, or registration status

Dependencies

  • Requires an API key credential for Go WhatsApp Web MultiDevice API authentication.

Troubleshooting

  • Ensure the device ID is correctly set or overridden if needed; otherwise, the default credential device ID is used.
  • If the phone number is invalid or not registered on WhatsApp, the node may return an error or empty contact details.
  • Common errors include network issues or authentication failures with the Go WhatsApp API; verify credentials and connectivity.
