Overview
This node enables sending WhatsApp messages through the Wuzapi service, optimized for AI workflows. It supports multiple message types including text, images, documents, audio, video, locations, contacts, stickers, buttons, lists, and polls. The "Send Sticker" operation specifically allows sending stickers to a specified phone number using different input formats (binary data, base64 string, or URL).
Common scenarios include automating customer support chats, broadcasting multimedia content, sending interactive messages with buttons or lists, and integrating AI-generated responses with rich media on WhatsApp.
Example use case: Automatically send a custom sticker as part of a chatbot response to enhance user engagement.

Dependencies

Binary property "X" not foundwill be thrown. - Invalid Phone Number Format: The phone number must be in international format without the "+" prefix. Including "@" in the phone number is allowed only if it already contains the full JID.
- Missing Required Fields: For base64 or URL sticker sources, the corresponding fields must be provided and valid.
- Unknown Operation Error: If the operation parameter is set incorrectly, the node will throw an
Unknown operationerror. - API Request Failures: Network issues or invalid credentials can cause request failures. Check API key validity and network connectivity.
To resolve errors, verify input parameters, ensure correct binary property names, and confirm API credentials are properly configured.
