For the configuration rules for payment authorization directory, please click [Detail] for reference. Supplementary note:

1. A maximum of 5 authorization directories are allowed. If you need to set multiple sub-directories, you may set the parent directory directly.

For example, if you need to configure https://pay.weixin.qq.com/wiki/ and https://pay.weixin.qq.com/app/ simultaneously, you may directly input https://pay.weixin.qq.com/.

1. The directory is case-sensitive, and it has to start with http or https, and end with "/". 3. The authorization directory cannot be in the IP format.

For example: https://8.8.8.8/test. 4. Assuming that https://www.weixin.com/pay.php is the address of the merchant's last page, the authorization directory needs to be https://www.weixin.com/.

It takes effect in 5-10 minutes after the payment authorization directory is configured.
