I am looking to use twitter Ads API for analytics purpose to get impressions details from one of our team Advertising Account.
I followed steps from Twitter API documentation to to signup for developer account , created developer APP, and requested access for Twitter ADS API through form submission. I have also got access for developer account as “Campaign Analyst” to my advertiser account.
I used POSTMAN to test GET Account call using all tokens from my developer account with OAuth 1.0, but I am still getting “UNAUTHORIZED ACCESS” issue.

"errors": [
    {
        "code": "UNAUTHORIZED_ACCESS",
        "message": "This request is not properly authenticated"
    }
],
"request": {
    "params": {}
}

}

Am i missing anything on this? My App Id is: 22639049

my GET call through POSTMAN still throws UNAUTHORIZED_ACCESS and same when using python. ANy suggestions?

twurl -H ads-api.twitter.com “/10/accounts” call just returns html in response which if i opened is error page.

Applications need to be approved to access the Ads API. Have you received an email indicating your application has been approved?

If so, I would recommend using Twurl to verify that your credentials and keys are set up correctly : Getting Started

Thanks for your response. Yes, I did received mail that Application is approved. Also, my request for elevated access is approved as well.

However, my GET call through POSTMAN still throws UNAUTHORIZED_ACCESS and same when using python. ANy suggestions?
I also used this :GitHub - twitterdev/twitter-python-ads-sdk: A Twitter supported and maintained Ads API SDK for Python. script and getting same UNAUTHORIZED_ACCESS error.
