How do you set the same headers for all requests in a Postman Collection?

Answer»

Postman COLLECTIONS allow using pre-request scripts at the individual request level and the collection level. We can add any SCRIPT that applies to all requests in the collection in the pre-request scripts. We can do it by following the below steps:

  • Right-click on the collection, NAVIGATE to the pre-request tab.
  • Add the below lines of code in the script to add a request header for all the requests present in the collection.
pm.request.headers.add({ KEY: 'TestHeader', value: 'testValue'});
  • Click on Update for saving the script.
  • Execute the request in the collection and check if the headers are added to the request in the Postman console.
