Add headers params to environment

[danny-dainton]

Hey @caudurieau

Is this what you’re trying to do?

Setting headers for entire collection/folder

As of 7.0.9 - You should be able to now do this in your Pre-request Scripts. You can use the following syntax: pm.request.headers.add({key: 'header_name', value: 'header_value' }) pm.request.headers.upsert({key: 'header_name', value: 'header_value' }) pm.request.headers.remove('header_name') EDIT: Fork this collection to see how it works directly in Postman: https://www.postman.com/postman/workspace/postman-answers/collection/9215231-ef055751-7385-45b4-a6f9-91bbd1c47fa5?ctx=documentation

Using the pm.request.headers.add({key: 'header_name', value: 'header_value' }) function in the Pre-Request Script at the Collection or Folder level, you would be able to programmatically set a header in one place that would be applied to multiple requests.
