Prepare Alipay

1. Create an application in the console of the Alipay Open Platform and note its APPID. See Find the APPID.
2. Generate an RSA2 key pair as the Alipay documentation describes. You get appPrivateKey.txt and appPublicKey.txt.
3. Upload the certificate to the application and download three files: alipayRootCert.crt, appCertPublicKey.crt, and alipayCertPublicKey.crt.

Store the certificates in Casdoor

1. On the Certs page of the Casdoor admin console, add a certificate named App Cert:

   Casdoor	Wert
   Type	Payment (x509)
   Certificate	Inhalt von appCertPublicKey.crt
   Private key	Inhalt von appPrivateKey.txt

   

2. Add a certificate named Root Cert:

   Casdoor	Wert
   Type	Payment (x509)
   Certificate	Inhalt von alipayCertPublicKey.crt
   Private key	Inhalt von alipayRootCert.crt

   

Add the provider in Casdoor

1. Go to Identity > Providers and add a provider with the following values:

   Casdoor	Wert
   Category	Zahlung
   Type	Alipay (Zahlung)
   Client ID	APPID from step 1.1
   Cert	App Cert from step 1.2
   Root Cert	Root Cert from step 1.2

   

2. Save the provider.

Add the provider to a product

Add the provider to the Payment providers of the product and save it.

Info

Alipay supports only Chinese yuan (CNY). Set the currency of the product to CNY. Casdoor rejects a product with Alipay in another currency when you save it.
