Script Callout

The Script Callout policy enables addition of custom JavaScript codes and Python codes that execute within the context of an API proxy flow.

Configuration

This policy can manage the function of Assign Variables, allowing the configuration of multiple context variables in the script, that is, addition or replacement/modification of payload and Context Variables. 

A basic script is available for Javascript and Python in the configuration panel, which acts as a template. Select the JAVASCRIPT/PYTHON option from the Source drop-down to view the sample script.

Sample scripts

Below are sample scripts available in the script editor section.

 // function definition
   function myFunction() {
    message.payload = '<Modified Payload >'; 
    message.contextVariable.'<context variable name>' = '<value of modified context variable>'; 
  }
    // function invocation
    myFunction();

 def myFunction():
          if(message.has_key('payload')):
             message['payload'] ='<modified payload >'
        
          if(message['contextVariable'].has_key('<context variable name>')):
            message['contextVariable']['<context variable name>'] = '<Value of context variable>'
          return message;
