Overview
This node integrates with the WeChat Official Account API to send customer service messages, specifically allowing sending image messages to users. It is useful in scenarios where a business or service wants to interact with their WeChat followers by sending images directly through the official account’s customer service messaging interface. For example, a company can use this node to send product photos, promotional images, or visual support materials to individual users who have interacted with their WeChat account.

Output
