The official account directly evokes WeChat payment
1. Explanation of the payment authorization directory:
1-1. The address of the page where the merchant finally requests to pull up the WeChat payment cash register is called the "payment directory", for example: https://www.weixin.com/pay.php.
1-2. The merchant’s actual payment directory must be consistent with the one set on the WeChat Pay merchant platform, otherwise it will report an error “The URL of the current page is not registered:” 2.
Log in to the WeChat Pay merchant platform (pay.weixin.qq.com) –> Product Center –> Development Configuration, usually takes effect within 5 minutes after setting.
3. Description of payment authorization directory verification rules:
3-1. If the payment authorization directory is set as a top-level domain name (for example: https://www.weixin.com/), then only the top-level domain name will be verified, and the suffix will not be verified;
3 -2. If the payment authorization directory is set to a multi-level directory, full matching will be performed. For example, if the payment authorization directory is set to https://www.weixin.com/abc/123/, the actual request page directory cannot be https:/ /www.weixin.com/abc/, also cannot be https://www.weixin.com/abc/123/pay/, must be https://www.weixin.com/abc/123/
4. Web page authorization When domain name
is developed for JSAPI payment, the user’s openid is required in the unified order interface, and to obtain openid, you need to set the domain name for obtaining openid on the public platform. Only the domain name that has been set is a valid domain name for obtaining openid, otherwise will fail to fetch. In Official Account Settings - Function Settings - Web Page Authorized Domain Name Settings. Note the download and location of the certificate.
