I'm testing bunch of API calls using POSTMAN. Instead of adding authorization header to each request, can I make it as a part of POSTMAN environment? So, I don't have to pass it with every request.

I have a posted simpler solution here which works for all cases stackoverflow.com/a/78736661/22860226JTX– JTX2024-07-11 16:18:48 +00:00Commented Jul 11, 2024 at 16:18

Yes, you can do this through Postman by assigning your header as an environment variable, let's say authorization, as follow:
then set you environment variable with its value as follow:

^ Agree with above comment, I came here looking for how to add a header to every request without having to edit each request manually. I have 58 requests in the suite I'm currently working on, and a new requirement that each one send an Authorzation header that wasn't present before.

This requires two steps. I tried this approach which is a single step for headers for all existing and new requests in a collection stackoverflow.com/a/78736661/22860226
In contemporary releases of Postman, you can just set your auth on the collection (or folder), and have every request inherit it (which I believe new requests do by default).

How do you add this after the collection has already been created? I dont find a way to edit the collection and add auth. It only appears to exist when you first create a collection.

Updated with screenshots showing how to do this in the Postman UI

Also, this, if you want to set custom Auth header(s), instead of the normal, selectable ones: postman.com/postman/workspace/postman-answers/collection/…
postman usually remembers your key-value pairs you send in header. So there is no need to add headers each request. Anyway you can configure a "Preset" with your auth token.

dang
yea but what if you need different preset to each environment
Not sure if this is what you're looking for, but we use a link-based API that requires auth headers on each request. If you go to Postman > Preferences > General and enable Retain headers when clicking on links, Postman will pass through your auth headers to the child links.
Hope that helps!

A much simpler way is to use API Key auth type for a collection.
It works for existing as well as new collections.
It lets you specify custom key and value which can be used as header as well as query params.

If you can't wait here is a work around I just made:
- Export your collection (data format v2.1)
- Open firefox , dev tools, scratch pad
- Paste the code below
- Replace the header information with your header
- Replace the var a with your contents of the exported .json file
- Run the script
- The copy(b) command will put the new data with in your clipboard
- In postman, click import > Paste Raw Text > Import > as a copy.
- Verify your requests have your header, and run it :)
var myHeader = {
"key": "X-Client-DN",
"value": "{{Postman-DN}}",
"description": "The User's DN Interacting with the system."
};
function addHeader(obj, header) {
if (obj.hasOwnProperty('request')) {
obj.request.header.push(myHeader)
}
if (obj.hasOwnProperty('item')) {
obj.item.forEach(function(element) {
element = addHeader(element, header);
});
}
return obj;
}
var a = {
"item": [{}, {
"request": {
"header": []
}
}, {
"item": [{
"request": {
"header": []
}
}]
}]
}
var b = addHeader(a, myHeader);
console.log(JSON.stringify(b, null, 2))
// Might have to run copy manually on console
//copy(b);
