How do I find my WeChat AppID and Secret?

Log in to the [WeChat Official Accounts Platform](https://mp.weixin.qq.com/), navigate to [Settings] -> [Development] -> [Basic Configuration] to find your unique AppID and generate your AppSecret.

An OpenID is a unique identifier for a specific user relative to your Official Account. It is required for most user-specific operations like sending messages or retrieving profiles.

Can I send messages to anyone?

Custom messages can only be sent to users who have interacted with your account in the last 48 hours. Template messages can be sent at any time but must follow specific structured formats and use-cases defined by WeChat.
