Integração com NotificaMe Hub API

Actions31

Overview

The NotificaMe Hub node for n8n enables integration with the NotificaMe Hub API, specifically allowing you to send audio messages via WhatsApp. This is useful in scenarios where automated or programmatic delivery of voice notes or audio files to WhatsApp users is required, such as customer support, notifications, or marketing campaigns.

Practical examples:

  • Sending a pre-recorded voice message to customers after they make a purchase.
  • Delivering audio alerts or reminders to users via WhatsApp.
  • Automating follow-up messages in audio format for enhanced engagement.

Properties

Below are the input properties relevant to the "WhatsApp" resource and "Enviar Áudio" (Send Audio) operation:

Display Name Type Description
Token Do Canal String Token do canal do WhatsApp. Required for authenticating requests to the WhatsApp channel.
Número Do Destinatário String Número do destinatário no formato internacional (ex: 5511999999999). The recipient's phone number in international format.
URL Do Áudio String URL pública do arquivo de áudio (MP3, OGG). Publicly accessible URL to the audio file to be sent.

Output

The node outputs a json object containing the response from the NotificaMe Hub API after attempting to send the audio message. The structure typically includes:

{
  "success": true,
  "messageId": "string",
  "status": "sent",
  "details": { /* additional API-specific fields */ }
}
  • success: Indicates if the request was successful.
  • messageId: Unique identifier for the sent message.
  • status: Status of the message (e.g., "sent", "queued").
  • details: Additional information provided by the API.

Note: The exact output fields may vary depending on the API response.

Dependencies

  • External Service: Requires access to the NotificaMe Hub API.
  • API Key: You must provide valid credentials (notificamehubApi) configured in n8n.
  • WhatsApp Channel Token: The "Token Do Canal" property must be set with a valid WhatsApp channel token.
  • Audio File Hosting: The audio file must be hosted at a publicly accessible URL (MP3 or OGG format).

Troubleshooting

Common Issues:

  • Invalid Token Do Canal: If the channel token is incorrect or expired, authentication will fail. Ensure your token is up-to-date.
  • Recipient Number Format: The recipient's number must be in international format (e.g., 5511999999999). Omitting country code or using an invalid format will cause errors.
  • Audio URL Accessibility: The audio file must be accessible from the internet. Private or inaccessible URLs will result in failure to deliver the message.
  • Unsupported Audio Format: Only MP3 and OGG formats are supported. Using other formats may lead to errors.

Common Error Messages:

  • "Authentication failed": Check your WhatsApp channel token and n8n credentials.
  • "Invalid recipient number": Verify the number format.
  • "Audio file not found or unsupported format": Ensure the URL is correct and the file is in MP3 or OGG format.
