Interact with Evolution API

Actions64

Overview

This node interacts with the "Evolution API" to send invitation links to WhatsApp groups. Specifically, for the "Grupo" resource and the "Enviar Link De Convite" operation, it sends a group invite link along with a custom message to specified phone numbers.

Common scenarios where this node is useful include:

  • Automating the distribution of WhatsApp group invite links to multiple contacts.
  • Sending personalized invitation messages to users to join specific groups.
  • Managing group invitations programmatically as part of marketing or community engagement workflows.

For example, a business could use this node to automatically send an invite link to new customers or subscribers, encouraging them to join a support or announcement group on WhatsApp.

Properties

Name Meaning
Nome Da Instância The name of the instance that will send the invitation.
ID Do Grupo The unique identifier (JID) of the WhatsApp group to which the invite link will be sent.
Mensagem Do Convite The message text sent along with the invite link. Default is "Segue o link do grupo".
Destinatários Comma-separated list of recipient phone numbers in international format (e.g., 5511999999999).

Output

The node outputs a JSON array containing the result of the invitation sending operation. Each item in the output corresponds to the response from the API after attempting to send the invite link to the specified recipients.

The exact structure of the JSON output depends on the API response but generally includes confirmation of sent invites or error details if any occurred.

No binary data output is indicated.

Dependencies

  • Requires an API key credential for authenticating with the Evolution API.
  • The node uses the base URL https://doc.evolution-api.com/api-reference for API requests.
  • Proper configuration of the API credential within n8n is necessary for successful execution.

Troubleshooting

  • Operation Not Supported Error: If the node throws an error stating the operation is not supported, verify that the resource and operation names are correctly set to "groups-api" and "send-invite-link" respectively.
  • Invalid Phone Numbers: Ensure that the "Destinatários" field contains valid phone numbers separated by commas without spaces, formatted in international format.
  • Missing Required Fields: All properties marked as required must be provided; otherwise, the node will fail.
  • API Authentication Errors: Check that the API key credential is correctly configured and has the necessary permissions.
