add aws signature to the postman script using pm.sendRequest

Question

I would like to use a postman pre-fetch script to refresh my app secret from an api protected by aws signature. I am able to make a basic authentication like this. However I need an aws signature authentication


var url = "https://some.endpoint"
var auth = {
  type: 'basic',
  basic: [
    { key: "username", value: "postman" },
    { key: "password", value: "secrets" }
  ]
};

var request = {
    url: url,
    method: "GET",
    auth: auth
}

pm.sendRequest(request, function (err, res) {
    const json = res.json() // Get JSON value from the response body 
    console.log(json)
});

hi just create a normal postman request that work properly and then copy that request to a variable by adding the below line in test script

 pm.environment.set("awsrequest", pm.request)

Now you can use the awsrequest variable to send use in pm.sendRequest

 pm.sendRequest(pm.environment.get("awsrequest"))

add aws signature to the postman script using pm.sendRequest
