Request logo assets from the Alipay+ CDN server

Alipay+ allows you to request logo assets from the Alipay+ CDN server. With such information, you need to display Alipay+ as a payment method correctly, including:

display Alipay+ as a payment method only when the .png asset exists
display Alipay+ with the logo in the .png asset

Construct the CDN URL

To request the logo asset, you need to construct a CDN URL as follows:

Production environment: https://resource.alipayplus.com/prod/<acquirerId>/sha256(<referenceMerchantId>)/<productCode>/<paymentCurrency>/<userRegion>/<logoPattern>/alipayplus.png
Sandbox environment: https://developers.alipayplus.com/cdn/sandbox/<acquirerId>/sha256(<referenceMerchantId>)/<productCode>/<paymentCurrency>/<userRegion>/<logoPattern>/alipayplus.png

Note: All parameters in the CDN URL are required. See the following table for details about how to specify values for the parameters.

The following table lists the request parameters in the CDN URL:
