- Needs network access to
https://waapi.app/api/v1. - The node uses the WaAPI REST API to send messages.
Troubleshooting
- Invalid Chat Id: If the chat ID format is incorrect or the chat does not exist, the API may return an error. Ensure the chat ID follows the correct pattern and the recipient is valid.
- Missing or Invalid API Key: Authentication errors occur if the API key is missing or invalid. Verify that the API key credential is correctly configured.
- Message Sending Failures: Network issues or API rate limits might cause failures. Check connectivity and API usage quotas.
- Mentions Not Working: Mentions only work in group chats and require the mentioned contacts to be included both in the message text and the mentions array.
- Reply To Message Id Format: Incorrect formatting of the reply message ID can cause errors. Follow the specified format exactly.
