Parameter

Mandatory

Type

Description

name

Yes

String

Parameter name.

  • If the parameter is located in Headers or Parameters, the value can contain letters, digits, periods (.), hyphens (-), and underscores (_), and must start with a letter. The value is case-insensitive.

  • If the parameter is located in Body, it is named application/json, application/xml, or application/text. However, the key-value pair in Body is used as the parameter name and parameter value. For example, if the parameter name is application/json and the parameter value is {"table":"apic01","id":"1"}, the backend uses table:apic01 and id:1 as input parameters.

  • Note: The parameter name must be unique. Otherwise, the parameters will be overwritten. When the parameters in Headers and Parameters are duplicate, the parameters will be overwritten. When the key-value pairs in Parameters and Body are duplicate, the parameters will be overwritten.
