Interface Parameter Usage Principles

The NSLB server IP address and port number involved in the request URLs of all interfaces in the following sections vary according to the deployment mode.

SaaS public cloud scenario: The NSLB server IP address is the IP address of the outer NSLB server (providing external access to virtualized services), and the port number is the port number provided for external services (corresponding to aicc-webproxy in NSLB routing rules). The default port number is 28050.
OP integrated deployment and OP independent deployment scenarios: The NSLB server IP address is the IP address of the NSLB server corresponding to the CC-iSales, and the port number is the port number provided for external services (corresponding to aicc-openproxy in NSLB routing rules). The default port number is 28080.

When using the RESTful interfaces provided by the CC-iSales, the third-party business side must follow the usage principles described in Table 1.

**Table 1** Interface parameter usage principle
Type	Description
Mandatory	Mandatory parameters must be contained in interface invoking requests sent from the business side to the CC-iSales in any case.
Optional	Whether to use optional parameters can be determined based on business requirements.
