How can I see these specific response headers?

Question

I am using Twitch's API to gather data for a web app I'm developing.

Per the documentation,

However, when I make the request in Postman, I don't see it.

They are in the header response section (I didn't screenshot the remaining half of the responses).

Am I looking in the wrong place?

I've looked in the Headers Response section of the API request I made. Additionally, I looked in the Headers Requests section in the console too.

Answer 1

The Headers Tab in Postman is request(input) headers not the response(output) headers data. It is located in the output area.

You can see (or assign) the response headers at Test tab.

Also curl 's -v option can see the headers from tesminal.

curl --location 'http://localhost:5000/user' \
-v \
--header 'Content-Type: application/json' \
--data '{
    "username": "username",
    "password": "1234"
}'

Result

You can see or assign to variable at Test Tab's by script

headers = pm.response.headers.all();
jsonHeader = JSON.stringify(headers);
console.log(jsonHeader)

headers.forEach(function(header){
    if(header.key == "Ratelimit-Reset"){
        pm.globals.set("Ratelimit-Reset", header.value)
        console.log(header.value)
        return;
    }    
})

you can assign global variable for specific key/value

Demo Server (emulate your Twitch's API server) by Python Flask.

app = Flask(__name__)

@app.route("/user", methods=["POST"])
def post_test():
    content_type = request.headers.get('Content-Type')
    if (content_type == 'application/json'):
        resp = Response(request.get_json())
        resp.headers['x-amzn-Requestid'] = '20122de8-3fd9-4439-b7f8-5c76a9dcf77e'
        resp.headers['x-amzn-Remapped-Content-Length'] = '6dd53770-ffa0-4f5f-95e6-b2fabe98c483'
        resp.headers['x-amz-apigw-id'] = 'e2994bb8-22c2-4ac5-b936-b541ac1bf99b'
        resp.headers['x-amzn-Rmapped-Date'] = '2023-08-17 16:45:43 UTC'
        resp.headers['x-Count'] = '1234'
        resp.headers['Ratelimit-Limit'] = '150'
        resp.headers['Ratelimit-Remaining'] = '98'
        resp.headers['Ratelimit-Reset'] = '1692306166'
        return resp, 201
    else:
        return 'Content-Type not supported!'

if __name__ == "__main__":
    app.run(debug=True)
