consult (Cashier Payment)

POST /v1/payments/consult

Use the consult API to initiate a payment consultation request to Alipay. This request is returned to the merchant with information on the different payment methods and its corresponding amount, country, currency, rules, and configuration.

The consult API enables merchants to:

  • Provide consumers with multiple payment methods without bearing any additional costs caused by a change in these payment methods, or managing the logic of selecting and sorting these payment methods.
  • Automate the selection and sorting of multiple payment methods.


A message consists of a header and body. The following sections are focused on the body structure. For the header structure, see:

Note: Set the data type of each field (except array) as String. This means that you must use double quotation marks (" ") to enclose the field value. Examples:

  • If the data type of a field is Integer and its value is 20, set it as "20".
  • If the data type of a field is Boolean and its value is true, set it as "true".
