Hi,

I am new to Postman, I want to print a response header value, in tests, if it exists.
For example if there is a RequstID header key and it has a value, I need a test to Say PASS when RequestID exists and prints its value in test result after PASS

Hey @singhsharad :wave:

Welcome to the Postman Community! :postman:

You can use this to print all headers to the Postman console:

let headers = pm.response.headers.all();
console.log(headers)

I’m not sure what exactly you would like your test to look like or check for but here’s an example of using a specific header:

let headers = pm.response.headers.all();

let filteredHeader = headers.filter(header => header.key === "Date");

pm.test(`Response has the Date header - Header Value: ${filteredHeader[0].value}`, function () {
    pm.expect(filteredHeader[0].key).to.eql('Date');
    pm.expect(filteredHeader[0].value).to.be.a('string');
});
