2)How to handle Conditional Workflow in Postman?

Condition flow is used to give a subsequent request flow based on the condition. It’s basically an if-else condition, if this condition is met then execute this API, if not then execute this API.

The pre-request or test script can utilize the postman.setNextRequest argument. The runner defaults to linear execution and proceeds to the next request if postman.setNextRequest is absent.

Execute This
Execute That
postman.setNextRequest("Req Name");
terminates execution

Refer below code for more understanding.

var customer = JSON.parse(responseBody);

if ( === undefined) {
  // No customer was returned, so don't run the rest of the collection
else {
  // Save the customer ID to a Postman environment variable

  // The "Edit Customer" request uses the "cust_id" variable
  postman.setNextRequest('Edit Customer');
