Abstract

The invention provides a service calling method and system, which relate to the field of information interaction. The method includes: the financial self-service terminal receives the transaction request input by the user; calls the corresponding transaction message template according to the transaction type in the transaction request; the financial self-service terminal obtains the corresponding transaction information according to the transaction message template; generates the corresponding transaction message according to the transaction information message, and send the transaction message to the server; receive the return message sent by the server, and obtain the control information from the return message according to the transaction message template; execute the transaction request according to the control information. According to the transaction message template, the acquisition of transaction information is realized, and a transaction message is generated and sent to the server. The return message obtained by the financial self-service terminal from the server reads the control information in the return message according to the transaction message template. When new application functions are needed, the new application can be quickly used by adding a transaction message template and reading and sending instructions according to the transaction message template.
