Using the CallReply mode

The most common and simple pattern for using a Connector in CallReply mode is:

1. Using the Config Editor, add a Connector in CallReply mode to your workspace. See Creating a Connector. Very few Connectors support this mode.
2. Set the mode (CallReply) and other connection parameters for this Connector in the Connection tab; required parameters are marked with an asterisk (*). Some Connectors require you to configure a Parser as well in the Parser tab.
3. Set up the Output Attribute Map; see [Output Attribute mapping](outputattributemapping.html#outputattributemapping "Output Attribute mapping is the process that accomplishes the moving of data from the Work entry in the AssemblyLine to the output destination in the connected system. Output Attribute maps are shown in the Attribute Maps window of the Connector, when brought up in the Connector Editor, with an arrow pointing from the Connector to an entity referred to as "[Target]". They are also shown in the Schema window, under Output Attribute map.").
4. Set up the Input Attribute Map; see [Input Attribute mapping](inputattributemapping.html#inputattributemapping "Input Attribute mapping is the process that accomplishes the moving of data from the input source to the Work entry in the AssemblyLine. Input Attribute maps are shown in the Attribute Maps window of the Connector, with an arrow pointing to the Connector from an entity referred to as "[Source]". They are also shown in the Schema window, under Input Attribute map.").

Keep in mind that Attributes from the Output Map are supplied to the connected system as input parameters; and Attributes mapped through the Input Attribute map contain the reply from the connected system.
